Answer:
Last year’s price = $2.96
Step-by-step explanation:
Given:
Current price of gasoline = $3.40
Higher rate = 15%
Find:
Last year’s price
Computation:
Last year’s price = Current price of gasoline [100 / (100 + 15)]
Last year’s price = Current price of gasoline [100 / (115)]
Last year’s price = $3.40 [100 / (115)]
Last year’s price = 2.95652
Last year’s price = $2.96
Answer:
The answer is k = 4.
Step-by-step explanation:
Given:
Y = 8 and X = 2.
Now, to solve direct variation.
direct with .
Now, using equation to solve direct variation:
Dividing both sides by 2 we get:
.
Therefore, the answer is k = 4.
14 - 12 = 2 dollars left over to buy containers. They each got one container each.
If this is a T/F question, then your answer is True .-.
7. Easiest method is substitution. Since y=x/2, then:
2x+3(x/2)=28
8.Substituting again, we get:
3x-6x=6
-3x=6
x=-2
(-2,6)
