Step-by-step explanation:
B and E
B-2 × 4 × 3) + (2 × 9 × 4)=96
E-3 × 4 × 4) + (6 × 4 × 2)=96
answer correct B and E
Answer:
it is 10 times greater
Step-by-step explanation:
hope this helps :)
Answer: x = 6
<u>Step-by-step explanation:</u>
2[3x - (4x - 6)] = 5(x - 6)
2[3x - 4x + 6] = 5x - 30
2[-x + 6] = 5x - 30
-2x + 12 = 5x - 30
<u>+2x </u> <u>+2x </u>
12 = 7x - 30
<u>+30 </u> <u> +30 </u>
42 = 7x
6 = x
