Answer:
x = 4. (Answer B)
Step-by-step explanation:
Combine the x-terms on the left side: -x + 3x = 2 + 6.
Simplifying further, 2x = 8, or x = 4. (Answer B)
Answer:
The answer is 60
Step-by-step explanation:
I am going to assume that A and a are the same variable. For future reference, a and A wouldn't be considered the same variable so be careful with that :)
We can first plug in 2 for a and 4 for b
4(2) + 2(4^2) - 2(2 - 3(4))
8 + 2(16) - 2(2 - 12)
8 + 32 - 2(-10)
8 + 32 - (-20)
8 + 32 + 20
60
Answer:
16 = a
Step-by-step explanation:
6 = a/4 +2
Subtract 2 from each side
6-2 = a/4 +2-2
4 = a/4
Multiply each side by 4
4*4 = a/4*4
16 = a
About 15.7, or 16 if you're looking for a whole number.
