For this case we have the following expression:
We apply distributive property, which by definition establishes that:
So:
Answer:
The number for x after the equals should be a 4
Answer:
x = 53°
y = 90°
Step-by-step explanation:
We can see that angle y is a right angle, so y is 90°.
The marked red line above may be a straight line, so x+37° = 90, because the marked orange line is perpendicular to the red line (y=90°).
x + 37° = 90
x = 53°

Answer:
x=11
Step-by-step explanation:
Subtract 3 from both sides
x+3=2x-8
x+3-3 =2x-8-3
Then simplify it
x=2x-11
Again, subtract 3 from both sides
x-2x=2x-11-2x
Simplify
-x=-11
Divide both sides and simplify and then you get x=11
