mafiozo [28]
Hi! :)

It sounds like you need to multiply this fraction. 

\frac{3}{8}*16=6

So, Marge used 6 total inches of tape.

What value of x is in the solution set of 9(2x + 1) < 9x – 18?
fredd [130]
To solve these kinds of problems, it is necessary to isolate x:

9(2x + 1) <span>< 9x - 18

Distribute 9:
18x + 9 </span><span>< 9x - 18

Subtracting 9 from both sides of the equation:
18x + 9 - 9 </span><span>< 9x - 18 - 9
18x </span><span>< 9x - 27

Subtracting 9x from both sides of the equation:
18x - 9x </span><span>< 9x - 27 - 9x
9x </span><span>< -27

x </span><span>< -3

Therefore, values of x </span><span>< -3 will satisfy the given equation.</span>

What does x equal? 3(x-7)=138+3x
Arturiano [62]
3(x-7) = 138 + 3x      First multiply
3x-21 = 138 + 3x      subtract 3x from both sides 
-21 = 138            

This is a false statement because -21 does not equal to 138 so the answer is no solution.
