What is the first step to solving this
equation?
4(2x-3)=4
Answer:
x=2
Step-by-step explanation:
Let's solve your equation step-by-step.
4(2x−3)=4
Step 1: Simplify both sides of the equation.
4(2x−3)=4
(4)(2x)+(4)(−3)=4(Distribute)
8x+−12=4
8x−12=4
Step 2: Add 12 to both sides.
8x−12+12=4+12
8x=16
Step 3: Divide both sides by 8.
8x /8 = 16 /8
x=2
Answer:
x = 2
Step-by-step explanation:
4(2x-3) = 4
⇔
4 × (2x-3) = 4 × 1
⇔
(2x-3) = 1 (divide both sides by 4)
⇔
2x = 1 + 3 (Move 3 to the right hand side)
⇔
2x = 4
⇔
x = 4/2
⇔
x = 2

If a dog is tied to a rope 15 feet long, how can it reach a bone
30 feet away? The rope isn't
T
E - TO - N - -HI-
5.4
13.4
8.6
10.6 1.4
10
Answer:
The other end of the rope was not tied to anything
Step-by-step explanation:
The dog was tied to a rope of 15 feet long and the bone was 30 feet away from where he was tied. The rope used to tie the dog is 15 ft long . But the other end of the rope wasn't tied to anything, this simply means the dog can easily approach and get the bone 30 ft away from where it was tied.
The other end of the rope was not tied to anything . This implies that the dog can simply reach the bone without breaking a sweat. The 15 feet rope was only tied to the dog , so it does not stop the dog from reaching a bone that is 30 ft away.
Shwetha comes to the swimming pool once every 12 days. Vinnie comes once every 4 days and Olga comes once every 10 days. Last Monday all of them were in the pool. In how many days all of them will meet at the swimming pool again? What day of the week will it be?
Answer:
60 days, Friday
Step-by-step explanation:
This problem is solved using concept of LCM.
LCM is the least number which is the common multiple of given set of different number.
To find the LCM we method of prime factors, the steps are given below
get all the all the prime factor of the given set of numberselect all the prime factors as many times they occur in given set of numbermultiply together the numbers selected together to get LCM________________________________________________
Given
frequency of visiting swimming pool by Shwetha = once in 12 days
factors of 12 = 2 * 2 * 3
frequency of visiting swimming pool by Vinnie = once in 4 days
factors of 2 = 2 * 2
frequency of visiting swimming pool by Olga = once in 10 days
factors of 10 = 2 * 5
minimum no of days after which they will be visiting together will be least common multiple of number of days after which they visit swimming pool individually.
Selecting the prime numbers with their highest occurrence
we have 2, 2, 3 ,5
multiplying them together we have
2 * 2 * 3* 5 = 60
therefore 60 is the LCM of 12, 4, 10
it means that Shwetha, Vinnie and Olga will visit swimming pool together once in 60 days
It is given that they visited on Monday and now they will visit after 60 days again.
since in one week there are seven days, every eighth day will be monday
so we divide 60 days by 7 to see how many cycles of monday has passed.
60/7 = 8 4/7
It suggest that 8 weeks has passed and they will meet on 4 days after Monday which will be Friday.
Thus they will meet meet at the swimming pool again in 60 days.
It will be Friday.
Answer:
60 days, friday

What are the x- and y-intercepts of the function graphed below?*
(0, 3) and (6,0)
(3,0) and (0,6)
(3,0) and (6.0)
(0.3) and (0,6)
Answer:
(3,0) and (0,6)
Step-by-step explanation:
(x,y) is the only way to make ordered pair.
The x was a 3 so you could cross out the first and last because they put the 3 in the y spot. When is should be (3,0).
Then the y was 6 and that I would be (0,6) so the third would also be crossed out because they put the 6 in the y spot.
So the answer is (3,0) and (0,6).
The temperature in a greenhouse should be 65 degrees or higher. One morning, the heater stopped working. The temperature dropped 6 degrees before someone fixed the heater. The temperature was still at least 65 degrees when the heater started working again. How can you best describe the temperature in the greenhouse before the heater stopped working?
The temperature in the greenhouse before the heater stopped working was at least 71 degrees Fahrenheit, based on the information that the temperature dropped 6 degrees but remained at least 65 degrees.
Explanation:As the temperature dropped 6 degrees and was still at least 65 degrees when the heater was fixed, we can set up a simple inequality to represent this situation:
Let T represent the temperature before the heater stopped working. After the heater stopped working and the temperature dropped by 6 degrees, the new temperature would be T - 6. According to the provided information, this new temperature was still at least 65 degrees, which gives us the inequality:
T − 6 ≥ 65
Adding 6 to both sides of the inequality, we find:
T ≥ 71
This means that the temperature in the greenhouse before the heater stopped working was at least 71 degrees.

Fernando bought a jacket for $185 and sold it for 1 1/2 times what he paid. Marisol spent 1/5 as much as Fernando on the same jacket but sold it for 1/2 as much as Fernando did. How much money did Marisol make? Explain your thinking using a diagram
We have been given that Fernando bought a jacket for $185 and sold it for 1 1/2 times what he paid.
Let us find selling price of jacket as:
[tex]\text{Selling price of Fernando's jacket}=\$185\times 1\frac{1}{2}[/tex]
[tex]\text{Selling price of Fernando's jacket}=\$185\times \frac{3}{2}[/tex]
[tex]\text{Selling price of Fernando's jacket}=\$277.5[/tex]
We have been given that Marisol spent 1/5 as much as Fernando on the same jacket.
[tex]\text{Cost of Marisol's jacket}=\$185\times \frac{1}{5}[/tex]
[tex]\text{Cost of Marisol's jacket}=\$37[/tex]
We are also told that Marisol sold the jacket for 1/2 as much as Fernando did.
[tex]\text{Selling price of Marisol's jacket}=\frac{\$277.5}{2}[/tex]
[tex]\text{Selling price of Marisol's jacket}=\$138.75[/tex]
The amount of money earned by Marisol would be selling price of jacket minus cost.
[tex]\text{Amount of money earned by Marisol}=\$138.75-\$37[/tex]
[tex]\text{Amount of money earned by Marisol}=\$101.75[/tex]
Therefore, Marisol made $101.75.

The Royal Fruit Company produces two types of fruit drinks. The first type is 60% pure fruit juice, and the second type is 85% pure fruit juice. The company is
attempting to produce a fruit drink that contains 70% pure fruit juice. How many pints of each of the two existing types of drink must be used to make 160
pints of a mixture that is 70% pure fruit juice?
Answer: 96 pints of the first fruit drink (60% pure fruit juice) and 64 pints of the second fruit drink (85% pure fruit juice).
Step-by-step explanation:
This question is a system of equations. First, we will define our variables:
Let x= number of pints of the first fruit drink (60% pure fruit juice), and then y = the number of pints of the second fruit drink(85% pure fruit juice).
We know that there are 160 total pints of the mixture. Therefore,
x + y = 160 .......... equation i
We are also aware that 70% of those 160 pints will be pure fruit juice, and they will come from either x or y.
For x pints of the first juice, there is
0.6x of pure fruit juice and for y pints of first juice, there is 0.85y of pure fruit juice. Therefore, we will have:
0.6x + 0.85y = 160 × 0.7
0.6x + 0.85y = 112
Multiply through by 100 to remove decimal. This will be:
60x + 85y = 11200 ........... equation ii
Combine both equations
x + y = 160 .......... i
60x + 85y = 11200 ........ ii
Multiply equation i by 60
Multiply equation ii by 1
60x + 60y = 9600 ........ iii
60x + 85y = 11200 ......... iv
Subtract iv from iii
-25y = -1600
y = 1600/25
y = 64
Since x + y = 160
x = 160 - 64
x = 96
Therefore , we will need 96 pints of the first fruit drink (60% pure fruit juice) and 64 pints of the second fruit drink (85% pure fruit juice).

a triangular section of a farm is enclosed by fences that are 2 meters, 6 meters, and 7 meters long, estimate the area of the section
Final answer:
To estimate the area of a triangular section with sides 2 meters, 6 meters, and 7 meters, you can use Heron's formula. The semi-perimeter is 7.5 meters. The estimated area of the triangle is approximately 5.56 square meters.
Explanation:
To estimate the area of a triangular section of a farm enclosed by fences that are 2 meters, 6 meters, and 7 meters long, we can use Heron's formula. First, we calculate the semi-perimeter (s) of the triangle:
s = (a + b + c) / 2s = (2 + 6 + 7) / 2s = 15 / 2s = 7.5 metersNow, we use Heron's formula to find the area (A):
A = √(s(s-a)(s-b)(s-c))A = √(7.5(7.5 - 2)(7.5 - 6)(7.5 - 7))A = √(7.5 * 5.5 * 1.5 * 0.5)A = √(30.9375)A ≈ 5.56 square metersTherefore, the estimated area of the triangular section of the farm is approximately 5.56 square meters.

The measure of XYZ is 45. The length of radius YZ is 6 inches. What is the area of sector XYZ?
(Use 3.14 for I.)
Answer:
area of a sector = 14.13 yards²
Step-by-step explanation:
XYZ is a sector of a circle. The radius YZ is 6 inches .The angle of the sector is given as 45°. The area of the sector can be solved as follows.
area of a sector = ∅/360 × πr²
where
r = radius
∅ = center angle
r = 6 inches
∅ = 45°
area of a sector = 45/360 × 3.14 × 6²
area of a sector = 45/360 × 3.14 × 36
area of a sector = 45/360 × 113.04
area of sector = 1/8 × 113.04
area of a sector = 14.13 yards²

A restaurant charged one customer $28.20 for 3 small dishes and 5 large dishes and charged another customer $23.30 for 4 small dishes and 3 large dishes. What will 2 small and 4 large dishes cost?
Answer:
Let s and l be the price of small and large dishes. The first equation is
While the second equation is
(I assume that you meant "4 small dishes and 3 large dishes")
If we multiply the first equation by 4 and the second by 3 we have
Subtract the two equation and you have
Substitute this value in one of the equation to derive
So, one small dish costs 2.9 and one large dish costs 3.9. This means that 2 small and 4 large dishes cost
