Answer:
If x varies directly as y, then x=ky. y=5 and x=2.5 are substituted into x=ky to find k.
2.5=5k
k=2.5/5
k=5.
K =5 is substituted in x=ky to find y where x is 10.
x=5y
10=5y
y=10/2
y=2
Answer:
35
Step-by-step explanation:
Multiply 40 by 0.125 (12.5%) and you get 5
Subtract 5 from 40
35
6x - 2x = 16
4x = 16 |divide both sides by 4
<h3>x = 4</h3>
Answer:
x=26
Step-by-step explanation:
first rewrite the problem since u know that G(x)=-48
-48=-3/2x-9
second you want to add the 9 to -48 which gives u -39
-39=-3/2x
third you want to times the reciprocal so it would be
-2/3 times -39/1
u can cross out the negatives and turn them into a positive
fourth you can cross cancel 3 and 39 which now the problem looks like this
2/1 times 13/1
which you would times 2 and 13 which your answer would be
26
