Well even if the answer are not shown it seems easy.
If lucy's mom gave her and her three friends the same amount of juice from 30 ounces that would mean it was dived up by 4.
30/4=7.5
so everyone got 7.5 ounces of juice.
Answer:
The solution would be (10, -3)
Step-by-step explanation:
In order to solve using elimination, multiply the top equation by -3 and then add the equations together.
-9x - 12y = -54
9x - 5y = 3
---------------
17y = -51
y = -3
Now that we have a value for y, we can put it into either equation and solve for x.
3x + 4y = 18
3x + 4(-3) = 18
3x - 12 = 18
3x = 30
x = 10
Given
x^5*k=a .................(1)
x^2*k=b .................(2)
We need to find x^3.
Solution:
On inspection, we note that (1)/(2) gives x^3 on the left hand side, but the division is valid on conditions that x ≠ 0 and k ≠ 0.
So we conclude:
(1) / (2)
=>
=>
on condition that

Sprint: $0.12 per minute
Sprint is the better deal.
