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

solve for h

5 - 8h = 21

Answers

Answer:

h = -2

Step-by-step explanation:

subtract 5 from both sides (5-8h-5=21-5)

simplify (-8h=16)

divide both sides by -8 (both -8's cancel, leaving 16/-8 which is -2.)

Michelle has a total debt of $28. She is trying to pay back $2 each week for the next 3 weeks. If Michelle is successful, which amount will represent the change in the amount of her debt?

Answers

Answer:

$22

Step-by-step explanation:

She gives 2 dollars per week for 3 weeks.

If she gives back 2 dollars each 3 weeks, we would solve for 2 x 3

2 x 3 = 6

28 - 6 = 22

$22 dollars represents her amount of debt.

Answer:

-6

Step-by-step explanation:

$28

$2/week

$28 - (2x3) = $22

$22 - $28 = -$6

Which one do you want answered?

please i need help in this sb

Answers

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.

Answer:

#1=15 #2=-9 #3=44

Step-by-step explanation:

1/2 times 2 times 8 + 7      #2:-2(-1)(-6)+3                   #3:  (7+3)^2 +4(7)(-2)

1/2 times 2 = 1                           -2times -1=2                                 (10)^2 +4(7)(-2)

1 times 8= 8                              2(-6)+3                                           100+4(7)(-2)

8+7=15                                     2times -6=-12                                   100+28(-2)

                                               -12+3=-9                                            100+-56
