Let x = hours spent babysitting on Saturday. Choose the equation that
Ne4ueva [31]

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

  • check all that applies

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

One of Eric's steps is 18in long. How many steps would he take to walk 1 mile?
Evgesh-ka [11]

Answer:

3520 steps

Step-by-step explanation:

The first thing we must do is figure out how many inches are in a mile. (There are 63,360 inches in one mile). With that out of the way, we can now divide these inches by 18, since each of Eric's steps are 18 inches long, and we want to determine how many steps he would have to take. 63,360 divided by 18 is 3520. This means our answer is 3520 steps, and that is how many steps he must take to walk 1 mile. I hope you understood and please let me know if you still need help!

navik [9.2K]

Answer:

y= \frac{3}{4}= 0.75

Step-by-step explanation:

To subtract the second equation from the first equation, you have to divide the equation as left of the equal sign and right of equal sign then do the calculation separately. The calculation will look like this

-3x +2y     =     7

-3x - 2y     =     4

_____________   -

(-3x +2y) - (3x -2y)     =   7 - 4

-3x + 2y + 3x + 2y     =   3

4y= 3

y= \frac{3}{4}= 0.75
