6-2x=6x-10x+20 solve for x
combine like terms and get all to the same side of equation
6-2x+10x-6x=20
10x-2x-6x+6=20
8x=20-6
8x=14
x=14/8=7/4
Answer:
B. 1/2
Step-by-step explanation:
If we plug in 0 for z, we get 0/0. Apply l'Hopital's rule.
Now when we plug in 0 for z, we get:
For the average to be 90,
(99 + 93 + x) / 3 = 90
or 192 + x = 270
or x = 270 - 192 = 78
Jim must score at least 78 in the third test.

Perform Multiplication
9+−6−6
Simplify
‐3
