Answer:
Step-by-step explanation:
9x + 8 = 7.5x + 17
1.5x = 9
x = 6 hours
The answer is C
Start by making two equations with the given information
The first would just be their total cans:
E + A = 257
The second would be:
5E - A = 13
Then combine the equations to eliminate one variable.
6E = 270
E = 45
Now plug E back into one of the equations.
45 + A = 257
A = 212
Answer:
A
Step-by-step explanation:
two complementary that have the same measure angels always equals 90
They would be 10 and 1/2
Multiplying by 1/2 is basically dividing by 2, so 10 times 1/2 would be 10 divided by 2, which is 5
10 + 1/2 is also 10 1/2
