Answer:
we need 2 equations to solve by elimination
Answer:
- Tadeo: 12 hours
- Dylan: 2 hours
Step-by-step explanation:
We can let d represent the number of hours that Dylan volunteered. Then Tadeo volunteered for 6d hours, and their total hours were ...
d +6d = 14
7d = 14 . . . . . . collect terms
d = 2 . . . . . . . divide by the coefficient of d
6d = 6(2) = 12
Tadeo volunteered 12 hours; Dylan volunteered 2 hours.
3 5/9, 4 8/9= 44/9 and 2/3=3/2 and when you add them it equals 96/27, and in simplest form it equals 3 5/9
C is the correct answer as 8% turned to a decimal is .08
