The equation that can be used to represent the situation given that x is the number of hours spent babysitting is 4(x + 8) = 56
<h3>How to write and solve equation</h3>
- Amount paid per hour for babysitting =$4
- Total amount made = $56
- Hours spent babysitting on Sunday = 8 hours
Total earned babysitting on Sunday = Hours spent babysitting on Sunday × Amount paid per hour
= 8 × 4
= $32
Number of hours he babysat on Saturday = $56 - (8 × 4) ÷ 4
= 56 - 32 ÷ 4
= 24 ÷ 4
= 6 hours
A. 8x+4 = 56
8x = 56 - 4
8x = 52
x = 52/8
x = 6.5
B. 4x+8 = 56
4x = 56 - 8
4x = 48
x = 48/4
x = 12
C. 8(x + 4) = 56
8x + 32 = 56
8x = 56 - 32
8x = 24
x = 24/8
x = 3
D. 4(x + 8) = 56
4x + 32 = 56
4x = 56 - 32
4x = 24
x = 24/4
x = 6

Answer:
Step-by-step explanation:
I'm going to use the process of elimination to get rid of the equations. The equation for slope is y=mx+b with b being the y-intercept. As you can see the y-intercept in this graph is 4 which removes the third equation as a possible answer. The slope is moving from left to right in a downwards direction which means it is a negative slope. The only answer with a negative slope is b therfore it is your answer.

Equation
That means that 8x + 14 = 14x - 15
Solution
8x + 14 = 14x - 15 Add 15 to both sides
8x + 14+15 = 14x Combine
8x + 29 = 14x Subtract 8x from both sides
8x - 8x + 29 = 14x - 8x Combine
29 = 6x Divide by 6
x = 29/6
x = 4 5/6
Answer
x = 4 5/6 or 4.833
8x + 14 = 8 * (4 5/6) + 14
8x + 14 = 38 2/3 + 14
8x + 14 = 52 2/3 or 52.6666
14x - 15 = 14 *(4 5/6) - 15
14x - 15 = 67 2/3 -15
14x - 15 = 52 2/3 or 52.666
