Answer: x=2 because for any y value the x value is always 2.
Answer:

Step-by-step explanation:
Option 1:
Using the following rule:

Put in our expression,
a = 2
n = 3
m = 2


Option 2:
Using the following rule:

Since our expression is the same as multiplying 2³ with itself, we can write it as a multiplication.

If we compare this with
, we can see that
a = 2
n = 3
m = 3 (in this case, n and m are equal)


Answer: 
Ok so
Q.1=B
Q.2=B
Q.3(a)=(d-45)+m+65
(b)=d+m+20
Answer:
1/2 = r
Step-by-step explanation:
7r + 21 = 49r
Subtract 7r from each side
7r-7r + 21 = 49r-7r
21 = 42r
Divide each side by 2
21/42 = 42r/42
1/2 = r
