Answer:
[tex]y = 9[/tex]
Step-by-step explanation:
[tex]28 + 7y = 91 \\ 7y = 91 - 28 \\ 7y = 63 \\ \frac{7y}{7} = \frac{63}{7} \\ y = 9[/tex]
Answer:
Y=9
Step-by-step explanation:
28 + 7y =91
first subtract 28 from both sides
28-28+7y=91-28
7y= 63
then divide both sides by 7
7y/7=63/7
y=9
ANSWER CHECK
to see if the answer is correct substitute the answer you got for the variable
y=9
28 + 7(9)
multiply 7 and 9
7(9)=63
63+28= 91

What is the scale factor?
1
1.25
2
2.5
Answer:
2
Step-by-step explanation:
The scale factor represented her is 2. You are going from 1 to 2, so multiply by two.
You are also going from 1.25 to 2.5, so multiply this by 2 as well.
A scale factor tells us how many time greater a measurement gets.

By mistake, you added salt instead of sugar to the
oil. How can you remove the salt?
Answer: Evaporate the water by boiling it in a pot with a lid or another container. This separates both substances as the boiling point for water is much lower than salt, this method is called simple distillation.
Answer:
Salt is ionic, and oil is covalent. If you add water, the salt will dissolve in the water, and the oil will float to the top. You could then skim the oil and start over with sugar. To double-check, you could even make sure the oil does not conduct electricity!

Step-by-step explanation:
We want to determine an expression equivalent to: [tex]\sqrt{128x^8y^3z^9}[/tex]
[tex]\sqrt{ab} =\sqrt{a}*\sqrt{b}[/tex]
Therefore:
[tex]\sqrt{128x^8y^3z^9}=\sqrt{128}*\sqrt{x^8}*\sqrt{y^3}*\sqrt{z^9}[/tex]
[tex]=\sqrt{64*2}*\sqrt{x^{4*2}}*\sqrt{y^{2+1}}*\sqrt{z^{8+1}}\\=8\sqrt{2}*\sqrt{x^{4*2}}*\sqrt{y^2*y}*\sqrt{z^{8}*z}}[/tex]
[tex]=8\sqrt{2}*x^4*y \sqrt{y}*z^4\sqrt{z}\\=8*x^4*z^4*\sqrt{2}*\sqrt{y}*\sqrt{z}\\=8x^4z^4\sqrt{2yz}[/tex]

StartRoot 7 squared EndRoot, StartRoot 7 EndRoot, Four-fifths, StartRoot 0.8 EndRoot, (StartRoot 5 EndRoot) Squared
Which statement can be used to create her list?
A: StartRoot 0.8 EndRoot is less than Four-fifths because 0.8 = four-fifths and the square root of a number less than 1 is less than the number itself.
B: StartRoot 7 EndRoot is greater than StartRoot 7 squared EndRoot because StartRoot 7 squared EndRoot = 7 and the square root of a number greater than 1 is greater than the number itself.
C: (StartRoot 5 EndRoot) squaredis less than StartRoot 7 EndRoot because (StartRoot 5 EndRoot) squared = 5 and StartRoot 7 EndRoot is between 6 and 8.
D: StartRoot 7 EndRoot is greater than Four-fifths because Four-fifths is less than 1 and the square root of a number greater than 1 is greater than 1.
Answer:
The correct option is D
Step-by-step explanation:
The given numbers are
√(7²), √7, 4/5, √0.8, (√5)²
Now, let us check their real values.
√(7²) = 7
√7 ≈ 2.646
4/5 = 0.8
√0.8 ≈ 0.894
(√5)² = 5
Now, checking the options,
A doesn't apply
B doesn't appy
C doesn't apply
D applies because √7 = 2.646 is greater than 4/5 = 0.8 because 4/5 is less than 1 and the square root of a number greater than 1 is greater than 1.
A student wants to sign up for a swimming class that charges $5 an hour. His parents are willing to spend up to $100 for swimming
lessons. Write an inequality representing the possible number of hours he could take swimming lessons for.
Answer:
[tex]x\leq 20[/tex]
Step-by-step explanation:
Given:
Charges of one hour swimming class = $5
Maximum amount that parents are willing to spend for swimming = $100
To find: inequality representing the possible number of hours, a student could take swimming lessons
Solution:
An inequality compares two values such that either one value is less than, greater than, or not equal to another value.
Let x represents number of hours spend by a student in swimming class.
As maximum amount that parents are willing to spend for swimming is $100 and charges of one hour swimming class is $5,
[tex]5x\leq 100\\x\leq \frac{100}{5} =20\\x\leq 20[/tex]
The volume of a rectangular prism is represented by the function x^3+9x+6x-16.The length of the box is x+2, while the height is x+8. Find the expression representing the width of the box
Answer:
Width = (x -1)
Step-by-step explanation:
Volume of rectangular prism = x³ + 9x² + 6x - 16
length * height *width = x³ + 9x² + 6x - 16
(x + 2)(x + 8 )* width = x³ + 9x² + 6x - 16

What is credit?
A.
an arrangement in which you receive money, goods, or services now in exchange for the promise of payment later
B.
an arrangement in which you receive goods or services in exchange for other goods and services
C.
an arrangement in which you receive money now and pay it back later with fees
I need the answer ASAP!!!! A.K.A. Right Now:(
Answer:
ypur answer would be a.
Credit is an arrangement where goods, services, or money are provided in the present with the promise of future payment, typically going into debt.
Credit is an arrangement where you receive money, goods, or services now and agree to pay for them later. This includes transactions with a credit card, where you obtain a good or service without immediate payment, but with a promise to pay the credit card company later, often with interest. Credit transactions essentially involve going into debt, as they create an obligation to pay in the future.
Choosing the correct answer from the provided options:
An arrangement in which you receive money, goods, or services now in exchange for the promise of payment later.
An arrangement in which you receive goods or services in exchange for other goods and services.
An arrangement in which you receive money now and pay it back later with fees.
The correct answer would be (A) since it entails receiving money, goods, or services now with the promise of payment at a later date, which matches the definition of a credit transaction.
Drag each number to the correct location on the equation. Not all numbers will be used.
ABC and RST are similar and have the same orientation. The hypotenuse of RST is on the same line as the hypotenuse of ABC and is twice the length of AB.
What is the equation of the line that contains the hypotenuse of RST?
-18
9
3
-6
-3
-9
6
18
Answer:
The equation of the hypotenuse line is y = -3·x + 9
Therefore, the correct options are -3 and 9
Step-by-step explanation:
The question asks to fill the boxes
y = _ x + _
We note that the equation is that of a straight line of the form;
y = m·x + c
Where:
m = Slope of the straight line graph and
c = Y intercept, that is the y-coordinate of the point on the line where x = 0
From the graph, we find the slope as follows;
[tex]Slope = \frac{y_2 - y_1}{x_2 -x_1} = \frac{(-9) -0}{6-3} = -3[/tex]
Therefore, m = -3
The y intercept is found by extending the hypotenuse line to the point where it touches the y axes that is at x = 0;
From the graph, it is observed that the line, when extended, touches the y axes at the point y = 9, therefore, c = 9
Hence we have, the equation of the hypotenuse line is y = -3·x + 9.
Answer:
y = -3x + 9

Plz help, what did I do wrong. Find the tangents of the acute angles in the right triangle. Write each answer as a fraction.
The tangents of the acute angles in a right triangle can be calculated by taking the ratio of the side opposite the angle to the side adjacent to the angle.
Explanation:In a right triangle, the tangent of an acute angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle. Let's say the acute angles of the right triangle are A and B, and the sides opposite to them are denoted as A and b, respectively. Then, the tangents of the angles A and B can be calculated as:
Tan(A) = a/b
Tan(B) = b/a
