Simplifying
P + -21 + -21 = 34 + -21
-21 + -21 + P = 34 + -21
Combine like terms: -21 + -21 = -42
-42 + P = 34 + -21
Combine like terms: 34 + -21 = 13
-42 + P = 13
Solving
-42 + P = 13
Solving for variable 'P'.
Move all terms containing P to the left, all other terms to the right.
Add '42' to each side of the equation.
-42 + 42 + P = 13 + 42
Combine like terms: -42 + 42 = 0
0 + P = 13 + 42
P = 13 + 42
Combine like terms: 13 + 42 = 55
P = 55
Simplifying
P = 55
$.75 bc 15 x 4 is 75 so that would make 75¢ or $.75
Answer:
z = 
Step-by-step explanation:
The ratio of corresponding sides are equal, that is
= 
( cross- multiply )
12z = 200 ( divide both sides by 12 )
z = 
=
