2c/15=8.8 5x+3x=5x+18 Because is on both sides( )of the equation, 3x must be equal to
( ) so that the equation is true.
8y+2y=2y+40 Because( )is on both sides of the equation, 8y must be equal to( )so that the equation is true.

How do i do this activity, is appreciated

Scenario: a rectangular plot of ground is 5 meters longer than it is wide. its area is 20,000 square meters. question: what equation will you find the dimensions? note: let w represent the width. options: w(w+5)=20,000 w^2=20,000+5 (w(w+5))/2=20,000 w+2(w+5)=20,000

If the tip varies directly with the number of guest which equation represents between the tip,t, and the number of guest,g?
