3s + 2p = 85.50....multiply by -1
3s + 4p = 123
--------------------
-3s - 2p = -85.50 (result of multiplying by -1)
3s + 4p = 123
--------------------add
2p = 37.50
p = 37.50/2
p = 18.75 <=== cost of the pants
3s + 4p = 123
3s + 4(18.75) = 123
3s + 75 = 123
3s = 123 - 75
3s = 48
s = 48/3
s = 16 <=== cost of each shirt
We know that the area of a rectangle is equal to the width multiplied by the length. So in this case the algebraic expression is (x+5)*(3x+10). You get 3x^2 +10x +15x +50= 3x^2 +25x +50.
Answer:
correct answer is : To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
