Jesse earns $6 an hour babysitting for his younger brother. His mom gave him $71 last week. This included his babysitting money
slamgirl [31]

Answer:

8.5 hours

Step-by-step explanation:

Okay, so he made $71 last week including his $20 allowance. We can take out the allowance 71-20= 51 dollars made from babysitting. But they are asking us to find how many hours he worked.. knowing he gets paid $6 an hour we can divide 51/6 = 8.5 hours babysitting.

Hope this helps :)

Find 4 consecutive even numbers whose sum is 156?
faust18 [17]
X + (x + 2) + (x + 4) + (x + 6) = 156
       x + x + x + x + 2 + 4 + 6 = 156
                                 4x + 12 = 156
                                       - 12   - 12
                                         4x = 144
                                          4        4
                                           x = 36
       x = 36
x + 2 = 38
x + 4 = 40
x + 6 = 42

If EFH = (5x + 1)°, HFG = 62°, and EFG = (18x + 11)°, find EFH
olga55 [171]

Given:

Consider the below figure attached with this question.

∠EFH = (5x + 1)°, ∠HFG = 62°, and ∠EFG = (18x + 11)°

To find:

The measure of ∠EFH.

Solution:

From the figure it is clear that ∠EFG is divide in two parts ∠EFH and ∠HFG. So,

\angle EFG=\angle EFH+\angle HFG

18x+11=(5x+1)+(62)

18x+11=5x+63

Isolate variable terms.

18x-5x=63-11

13x=52

Divide both sides by 13.

x=\dfrac{52}{13}

x=4

The value of x is 4.

\angle EFH=(5x+1)^\circ

\angle EFH=(5(4)+1)^\circ

\angle EFH=(20+1)^\circ

\angle EFH=21^\circ

Therefore, the measure of ∠EFH is 21°.
