Every absolute value MUST be 0 or greater (positive); thus, <span>| 5x + 13| = -7 has no solution due to the - number on the right.

Answer:
12
Step-by-step explanation:
Average age of 5 boys = 11 year
Sum of age of 5 boys = 11*5 = 55
Age of sixth boy = 17 years
Sum of age of 6 boys = 55 + 17 = 72
Average age of 6 boys= 72/6 = 12
It's going to be the first one...
How you solve this is just insert the number of hours you want for X then solve the equation.
15 * 1 = 15
15 + 30 = 45
15 * 3 =45
45 + 30 = 75
-10 times 12
