1. Because there are 8 fewer than DOUBLE the number of students in chorus, then it would be 2x. We also know there are 8 fewer, meaning subtract.
Therefore the equation is 2x-8=54 (A)
2. So in this problem, let e represent Gage's age. Now multiply by 3 because Everly is 3 times his age. She is also two years older, meaning more, or add.
So the equation is 3x+2=23. (C)
3. Again, let c represent the cost of skis. Now 8% written in decimal form is 0.08c. And since there's more than in the equation, we need to add.
The equation is c+0.08c=162. (A)
4. This is a little different. We are given the amount of pages Ivy read. Now because Tucker read 3 times as many pages as Ivy, and Ivy read 72, we must divide since they are giving us the number of pages Ivy read.
Therefore, the number of pages Tucker read is n/3-10=72. (D)
5. So equation to find perimeter of a rectangle is 2l+2w. Now we are given the width and the perimeter, so plug that in. That gives us 2l+2(8)=60. Now algebra. 2l+16=60. (C)
6. So we are given how much Lexi scored. Now we find how much Madelyn scored. Since Lexi scored 3 times fewer than Madelyn, we have to multiply 3 to find Madelyn's score. And since Lexi scored 27 points few, we add.
The equation would be 3p+27=120. (A)
