Answer:
x=-6
Step-by-step explanation:
5x-x-6=6(2x+7)
4x-6=<em>6(2x+7)</em>
4x-6=<em>12x+</em><em>42</em>
-8x=48 |:(-8)
x=-6
Answer:
15/56
Step-by-step explanation:
To get the answer, you find the least common denominator of 4 and 7 which is 28. 1/4 is equal to 7/28. 2/7 is equal to 8/28. if you subtract 7/28 from 8/28, you get one twenty-eighth (1/28). Half of 1/28 is 1/56. To add 1/56 and 7/28, multiply the numerator and denominator of 7/28 by 2. You will get 14/56. Add 14/56 and 1/56 and the answer is 15/56. I'm pretty sure this is the answer. Thanks!
<span>7/3+3(2/3−1/3)^2
= 7/3 + 3(1/3)^2
= 7/3 + 3(1/9)
= 7/3 +1/3
= 8/3</span>
You need 3a^3 to equal a^3, so you would need at subtract 2a^3.
Since the problem is addition, add - 2a^3:
3a^3 + -2a^3 = 3a^3 - 2a^3 = a^3
Then you have -5b^3 and you need it to equal b^^3, so you would need to add 6b^3:
-5b^3 + 6b^3 = b^3
First box would be -2
Second box would be 6
