Please help me! I'm terrible at math

Hatshy [7]3 years ago

Answer:

(3.) x = 45

Step-by-step explanation:

Because the lines are parallel and cut by the same line, the angles within are equal as well.

Which means that...

Angle GE = Angle EFD

Therefore (2x-30) = (x + 15)

2x - 30 = x + 15

    +30       +30    (add 30 to both sides to get rid of the -30)

2x = x + 45

-x    -x                   (subtract x from both sides to get rid of the single positive x)

x = 45

If w varies jointly as x and y when w = 12, x = 2, and y = 18, what is the value of y when w = 16 and x = 6?
hichkok12 [17]
Joint variation means that w=kxy where k is constant.
Finding k:
12=k*2*18
12=36k
k=1/3

Now plug in second set of values
16= 1/3*6*y
16=2*y
y=8

Final answer: 8
