31.7 + 42.8 + 26.4 + x/4 = 39.1
Add up all the plain numbers on the left side:
100.9 + x/4 = 39.1
Subtract 100.9 from each side:
x/4 = 39.1
Multiply each side by 4:
<em>x = 156.4</em>
Distribute and simplify.
2(x+8)+6x
2x+16+6x
8x+16
8(x+2)
8x + 9 = 42
8x +(9-9)=42-9
8x=33
8x/8=33/8

Hope this helped!
The correct answer is D.
The LCD, least common denominator, is the smallest denominator that both denominators will go into. The LCD of 5 and 7 will be 35; the variable portion will be b³c, since that is the smallest thing the second fraction can go into.
This gives us a denominator of 35b³c.
