What question do u need help with?
Answer:
Yes
Step-by-step explanation:
7 = x
5 = y
5 = X + - 2
5 = X - 2
If X is 7 then
5 = 7-2
5=5
yes
The best estimate would be 121/15 = 8.1
9x-22=23+4x
Now you subtract 4x from both sides to get the variable on one side..
5x-22=23
Now solve as you would solve a 2 step equation.
5x=45
Divide both sides by 5 to get the variable by itself.
x=9
The four powers have zero (0) in common
<h3>Indices </h3>
