Answer:
12x(2x2^3)=120
Step-by-step explanation:
12x2+2^3=120
(12x2)+2^3=32
12x(2+2^3)=?
12x(2+8)=?
12x10=120
Answer:
150000
Step-by-step explanation:
5.7 - 0.38 = 5.70 - 0.38 = 5.32
70 - 38 = 32
Answer:
Instead of moving the 3x to the opposite side of the equation they moved the 2x. And the correct answer is x=-6 not x=6.
Step-by-step explanation:
Student Work:
2(x + 4) – 8 = 3x+10-4
2x + 8–8 = 3x + 6
2x = 3x + 6
- 3x – 3x
X = 6
My work:
2(x+4)-8=3x+10-4
2x+8-8=3x+6
2x=3x+6
-x=6
x=-6
