Answer:

Number of hours= 20 hours

Step-by-step explanation:

Giving the following information:

Net savings (babysitting)= 250 - 110= $140

Rate per hour= $7

<u>To calculate the number of hours that Melissa worked as a babysitter, we need to use the following formula:</u>

Number of hours= net savings / rate per hour

Number of hours= 140 / 7

3x + y = 17<br> 4x - y = 18
Inessa05 [86]
The two equations given are
3x + y = 17 and 4x - y = 18
Now we will first take one equation
3x + y = 17
Then
y = 17 - 3x
Now replacing the value of y in the second equation we get
4x - y = 18
4x - (17 - 3x) = 18
4x + 3x - 17 = 18
7x = 35
 x = 35/7
   = 5
Putting the value of x in the first equation we get
3x + y = 17
(3 * 5) + y = 17
15 + y = 17
y = 17 - 15
y = 2
So the value of x is 5 and y is 2

Hi!

So do 91/7 = 13

which means Frances can do 13 oil changes in 1 day

To find how many he can do in 11 days, multiply 13 and 11

11*13 = 143

Frances can do 143 oil changes in 11 days.

Hope this helps!
