For each equation, explain what you could do first to each side of the equation so that there would be no fractions. You do not have to solve the equations (unless you want more practice). 1. 3 x − 4 8 = x + 2 3

2. 3 ( 2 − r ) 4 = 3 + r 6

3. 4 p + 3 8 = p + 2 4

4. 2 ( a − 7 ) 15 = a + 4 6

Based on what i know about mean, this doesn't add up.

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (-4, 0) and (6,0). the y-intercept of thefirst parabola is (0, –12). the y-intercept of the second parabola is (0-24). what is the positive difference between the avalues for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth.
