Answer:Benjamin’s age = 30 and David’s age = 6
Explanation:
Let x be the age of Benjamin
Let y be the age of David
x + y = 36
And 2x + 2y = 72
If we plug 30 for x and 6 for y we get:
30 + 6 = 36
36 = 36
2(30) + 2(6) = 72
60 + 12 = 72
72 = 72

Answer:
negative
Step-by-step explanation:
The new hourly rate is $6.15. To find this, you have to set up the rate and percent as x/6=2.5/100. You cross multiply. x times 100 equals 100x. 6 times 2.5 equals 15. It would be written as 100x/100=15/100. You divide by 100 to leave x by itself. 15 divided by 100 equals 0.15. So, x equals $0.15 cents. You add 6 and 0.15. Together, they add up to $6.15. Hoped this helps!
