Answer:

I got 9.

Step - By - Step Explanation:

7x - 13 = 5x + 5

7x = 5x + 18

2x = 18

x = 18 ÷ 2 = 9

x = 9

7(x) - 13 = 5(x) + 5
7x - 91 = 5x + 25
7x - 5x - 91 = 25
2x - 91 = 25
2x = 25 + 91
2x = 116
x = 58

Bill ate 1/4 pound of trail mix on his first break during a hiking trip. On his second break, he ate 1/6 pound. How many pounds
tino4ka555 [31]
Since we know that he ate 1/4 pound one time, and 1/6 another time, we have to add up the fractions. 

1/4+1/6

LCM of 4 and 6 = 12

3/12 + 2/12 

Add the numerators: 

5/12

So, he ate 5/12 of a pound of bars in both breaks. 

Hope this helps!
