Answer:
x/2 + 21 = 36
First we get rid of constants to isolate the variable.
In order to do that we must do the inverse operation.
Inverse operation of addition is subtraction.
-21 -21(subtracting 21 from both sides, whatever we do to the left side we do it to the right side too)
x/2 = 15
inverse property of division is multiplication
x2 x2
X = 30

Answer:
$7.30
Step-by-step explanation:
If you add .40 + .60 you'll get 1 and if you add that to the 6.30 then you'll get $7.30
The answer is 5.
The triangle is 90° triangle, which means we can use the pythagorean theorem.
a^2xb^2=c^2
3^2=9
4^2=16
9+16=25
That means c^2=25
And the answer is c=5
0.5 = 0.500
0.485<0.500
hope that helps!
