Answer 1

Answer: 10

Step-by-step explanation:

8v - 4(v + 8 ) = 8

Distribute

8v - 4v - 32 = 8

Combine like terms

4v - 32 = 8

Add 32 to both sides

4v = 40

Divide by 4 on both sides

V = 10

The first question the answer is 15.
This happens because 2×8 = 16. After that you multiply 16 by half. What do you do that the answer is eight then you add seven and get 15.

For the second question you do -6 times negative one. After that you’ll get six. Then you would have to multiply it by -2 and get -12. Then you add -12+3 and then you get -9. Your answer is -9

For the third question you would add 7+3 and get 10. Then you would have to multiply it to the second power and get 1000. Then you would have to add 1000 with four. Then you multiply seven by -2 and multiply that by four. Then you would get -56
Your answer would be -56.

It was very complicated. If I get something wrong I am sorry. I hope I helped.

A bag of chocolates is labeled to contain 0.384 lbs. The actual weight of the chocolates is 0.3798 lbs.

Answers

Answer:

The answer to your question is the chocolates are slightly lighter than the weight stated on the label.

Step-by-step explanation:

Data

The label says 0.384 pounds

Actual mass = 0.3798 pounds

Process

To solve this problem the only thing we must do is substrate the actual weight of chocolates to the weight of chocolates stated on the label.

If the result is positive, then the chocolates are lighter

If the result is negative, then the chocolates are heavier

0.384 pounds - 0.3798 pounds = 0.0042

ok? what’s the question? the difference is 0.0042

find the value of x. if x is 2 for example multiply that 6 times to find the numerator. 2 x 2 x 2 x 2 x 2 x2 = 64. multiply that with 3 which is 192. now to find the denominator you are going to multiply 2 three times. 2 x 2 x2 = 8. now divide the denominator with the numerator which equals 8.

The answer is 3x^3 and this is because when you are dividing you actually subtract so x^6(top)-x^3(bottom)
is x^3 and since there is not another 3 in the denominator the 3 stays at the top
