determine the value of x?
Answer:
see explanation
Step-by-step explanation:
Using the rule of exponents
[tex]a^{m}[/tex] ÷ [tex]a^{n}[/tex] = [tex]a^{(m-n)}[/tex], then
[tex]a^{x^2-5x}[/tex] = [tex]a^{6}[/tex], hence
x² - 5x = 6 ( subtract 6 from both sides )
x² - 5x - 6 = 0 ← in standard form
(x - 6)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 1 = 0 ⇒ x = - 1
Answer:
x=6, -1Step-by-step explanation:
Using the rule of exponents:
a^{m} ÷ a^{n} = a^{(m-n)} , then
aˣ² ÷ a^{5x} = a⁶
⇒ a^{x^2 - 5x} = a⁶
⇒ x² - 5x = 6
x² - 5x - 6 = 0
(x - 6)(x + 1) = 0 [middle term splitting]
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6 ║ x + 1 = 0 ⇒ x = -1

Is it possible for two numbers to have a difference of 6, and also a sum of 6?
Answer:
The only possible numbers are 6 and 0.
Step-by-step explanation:
We are given the following information in the question:
Let x and y be the two numbers whose difference is 6 and whose sum is also 6.
We can write it in the form of the equation:
[tex]x - y = 6\\x+y =6\\\\\text{Adding the two equations}\\(x-y) + (x+y) = 12\\2x =12\\x = 6\\\\\text{Putting this value of x in one of the equations}\\6 + y = 6\\y = 0[/tex]
Hence, the only possible numbers are 6 and 0.
It is possible as the numbers are 0 and 6.
Let the numbers be a and b.
Based on the question, the equation to solve the question will be:
a - b = 6 ........ i
a + b = 6 ........ ii
From equation i, a = 6 + b
Put the above into equation ii
a + b = 6
(6 + b) + b = 6
6 + 2b = 6
2b = 6 - 6.
2b = 0
b = 0/2
b = 0
Therefore, the value of a will be:
a = 6-0 = 6.
The numbers are 0 and 6.

Joanie is organizing her closet. She has 3 times as many black shirts as gray shirts, plus 3 new black shirts she just bought. She has 5 times as many white shirts as gray shirts, minus the 1 white shirt she donated. Joanie has 2 times more gray shirts than brown shirts. If she has the same number of black and white shirts, how many gray shirts does Joanie have?
A. 2
B. 1
C. 4
Answer:
Option A. 2
Step-by-step explanation:
To solve this problem we can write equations for each shirt color.
Let's call:
b = black shirts
g = gray shirts
w = white shirts
B = brown shirts
If you have 3 times more black shirts than gray shirts and buy 3 more black shirts then:
[tex]b = 3g +3[/tex] (i)
If you have 5 times more white shirts than gray shirts and gave a white shirt then:
[tex]w = 5g -1[/tex] (ii)
It has 2 times more gray shirts than brown camsas, then:
[tex]g = 2B[/tex] (iii)
It has the same amount of black and white shirts
[tex]b = w[/tex] (iv)
We want to find the number of gray shirts.
Then replace (iv) in (ii)
[tex]b = 5g -1[/tex] (v)
Now substitute (v) into (i) and clear g.
[tex]5g -1 = 3g +3\\\\5g -3g = 3 +1\\\\2g = 4\\\\g = 2[/tex]
Joan has 2 gray shirts
Joanie has 2 gray shirts, option A.
To determine the number of gray shirts Joanie has, we'll set up and solve a system of equations. Let G represent the number of gray shirts and let B, W, and R represent the number of black, white, and brown shirts, respectively.
Given the information:
Joanie has 3 times as many black shirts as gray shirts plus 3 new black shirts: B = 3G + 3.She has 5 times as many white shirts as gray shirts minus 1 white shirt: W = 5G - 1.Joanie has 2 times more gray shirts than brown shirts: G = 2R.She has the same number of black shirts as white shirts: B = W.1. Set the equations for black and white shirts equal:
3G + 3 = 5G - 1
2. Simplify and solve for G:
3 + 1 = 5G - 3G
4 = 2G
G = 2
Thus, Joanie has 2 gray shirts.
A rectangular prism has a length of 9in., a width of 4in., and a height of 1 1/2in. The prism is filled with cubes that have edge lengths of 1/2. How many cubes are needed to fill the rectangular prism?
I NEED HELP ASAP!!
To fill a rectangular prism with dimensions 9in. by 4in. by 1.5in. using half-inch cubes, you need to divide the volume of the prism (54in.^3) by the volume of a cube (0.125in.^3), resulting in 432 cubes needed.
Explanation:To determine how many half-inch cubes are needed to fill the rectangular prism, we must first calculate the volume of the prism and then the volume of a single cube. Next, we divide the volume of the prism by the volume of a cube to find the number of cubes needed.
Calculating the Volume of the Rectangular Prism
The volume of a rectangular prism is found by multiplying its length by its width by its height. Volume of the prism = length × width × height = 9in. × 4in. × 1.5in. = 54in.3.
Calculating the Volume of a Cube
The volume of a cube is found by raising the length of an edge to the third power. Volume of a cube = edge length3 = (0.5in.)3 = 0.125in.3.
Number of Cubes Needed
To find the number of cubes needed to fill the prism, divide the volume of the prism by the volume of a cube. Number of cubes needed = Volume of the prism / Volume of a cube = 54in.3 / 0.125in.3 = 432.
Therefore, 432 half-inch cubes are needed to fill the rectangular prism.

To determine if a set of measurements could be the side lengths of a right triangle, we need to check if the Pythagorean theorem holds true. Option D, with side lengths 54 in, 72 in, and 90 in, satisfies the theorem and represents a right triangle.
Explanation:In a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. This is known as the Pythagorean theorem: a^2 + b^2 = c^2.
So, to determine if a set of measurements could be the side lengths of a right triangle, we need to check if the Pythagorean theorem holds true. Let's check each option:
Option A: (54)^2 + (72)^2 = 2916 + 5184 = 8100. However, the measurement for the third side (108) does not satisfy the theorem, so this is not a right triangle.Option B: (54)^2 + (81)^2 = 2916 + 6561 = 9477. This also does not satisfy the theorem, so this is not a right triangle.Option C: (45)^2 + (72)^2 = 2025 + 5184 = 7209. Again, this does not satisfy the theorem, so this is not a right triangle.Option D: (54)^2 + (72)^2 = 2916 + 5184 = 8100. This time, the measurement for the third side satisfies the theorem (90), so this is a right triangle.Therefore, the correct answer is option D: 54 in, 72 in, 90 in.

Use the GCF of 10 and 15 to cross-cancel and reduce and solve [tex]\frac{5}{15}x\frac{5}{10}[/tex]
Answer:
5
Step-by-step explanation:
Final answer:
Using the GCF of 10 and 15, which is 5, we cross-cancel the fractions 5/15 and 5/10 to reduce them to 1/3 and 1/2 respectively. Multiplying these reduced fractions, we obtain the final answer of 1/6.
Explanation:
To solve the fraction 5/15 × 5/10, we first identify the Greatest Common Factor (GCF) of the numerators and denominators. The GCF of 10 and 15 is 5. Using this GCF, we cross-cancel to reduce the fractions before multiplying.
Firstly, we divide both 10 and 15 by the GCF, which gives us:
10 ÷ 5 = 2
15 ÷ 5 = 3
Applying cross-cancellation to the original expression, we get:
(5 ÷ 5) / (15 ÷ 5) × (5 ÷ 5) / (10 ÷ 5)
1/3 × 1/2
Multiplying these reduced fractions gives us:
1/3 × 1/2 = 1/6
Thus, the result of multiplying 5/15 by 5/10, after cross-cancelling the common factors, is 1/6.
1.The temperature was 80∘F and then fell 20∘F. 2.The temperature was -13∘F and then rose 9∘F. 3.The temperature was -5∘F and then fell 8∘F.
Answer:
The initial temperature is 80 °F.
The final termperature is 20°F.
During this period, fell 60 °F which represents a percentage of
[tex]\frac{60}{80} \times 100= 75\%[/tex]
We repeat the process for the rest.
From -13 °F to 9 °F, the temperature arose 22 °F, which is equivalent to
[tex]\frac{22}{13} \times 100= 169.23 \%[/tex]
From -5 °F to 8 °F, the temperature fell 13 °F, which is equivalent to

It would take 120 minutes to fill a swimming pool using water from 5 taps. How many minutes will it take to fill the pool if only 3 taps are used?
Final answer:
It will take 72 minutes to fill the pool using only 3 taps.
Explanation:
To find out how many minutes it will take to fill the pool using only 3 taps, we can set up a proportion.
If it takes 120 minutes to fill the pool using 5 taps, then the rate at which water flows from the taps is 1 pool/120 minutes/tap.
Using this rate, we can set up the proportion:
5 taps / 3 taps = 120 minutes / x minutes
Cross-multiplying and solving for x gives us:
x = (3 taps * 120 minutes) / 5 taps = 72 minutes
So, it will take 72 minutes to fill the pool using only 3 taps.

Given: circle k(O), m FE =56°, FD=ED, m∠EFD=76°
Find: m∠EFO
Based on the inscribed isosceles triangle shown below, the measure of angle EFO is 62°.
In Euclidean Geometry, the measure of an intercepted arc is equal to the central angle of a circle. Based on the information provided above, the measure of arc FE is equal to 56°, so the measure of the central angle FOE must be equal to 56°.
By critically observing triangle FOE, we can logically deduce that it is an isosceles triangle with base FE because segments FO and EO represent the radii of circle O.
Since an isosceles triangle comprises two (2) side lengths that are equal and two (2) base interior angles that are congruent, we have:
FD = ED
m∠EFO ≅ m∠FEO
By applying triangle sum property to triangle FOE, we have;
m∠EFO + m∠FEO + mFE = 180°
2m∠EFO + m∠FE = 180°
2m∠EFO + 56° = 180°
m∠EFO = (180° - 56)/2
m∠EFO = 62°

Find the horizontal asymptote....
Answer: [tex]y=0[/tex]
Step-by-step explanation:
The given function is a rational function:
To solve the given problem you must keep on mind that:
- An asymptote is define as a line that the graph of the function approaches but never touches.
- In rational functions, if the degree of the polynomial in the numerator is lower than the degree of the polynomial in the denominator, then the horizontal asymptote is located at y=0.
In the given function, the degree of the polynomial in the numerator (which is 1) is lower than the degree of the polynomial in the denominator (whic h is 2). Therefore, the horizontal asymptote is located at [tex]y=0[/tex]
