It would be 20 no? because there if it is x = x then x = 20 so 20 = x
same thing for all
Answer:
Yes
Step-by-step explanation:
4(3) - 28 = -16
12= -16 + 28
12 = 12
Hope that helps!
Answer:
36
Step-by-step explanation:
75% is the same as 3/4th so if you divide 27 by 3 you get 9 and 9 * 4 = 36
Answer:
w = x + 50
Step-by-step explanation:
The dog is 50 pounds. The person's weight is x. You are trying to find the total weight of the dog and person. Therefore, you need to combine the two values to get the total, making the equation w = x + 50, or x + 50 = w
Answer and Step-by-step explanation:
Alot of these can be solved with the table up above the problems.
<h2>
A, B, and C.</h2><h2>
</h2>
According to the table, every time a value has an exponent of 0, it would equal to 1. Since all A B and C values follow the 0 exponent, their value is 1.
<h2>D.</h2><h2 />
According to the table, when we have a negative exponent, the number gets turned into a fraction of 
Since our value is 9^-2, do as followed :

Solve what is 9^2 :
![[\frac{1}{81} ]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B1%7D%7B81%7D%20%5D)
<h2 /><h2>E.</h2><h2 />

This question is different, since we have to go backwards, we have to switch the negative exponent to a positive exponent and rid the fraction.

<h2>F.</h2><h2 />

Since we have one negative exponent, follow the fraction rule but instead of having one as the numerator, have 5a^3.

<h2>Fill in the table :</h2><h2 />

Since -3 is in parenthesis, we can rid the negative along with the parenthesis :

Follow the negative exponent rule :

Follow the negative exponent rule yet again :
