Question 7

Describe how to model -3x + 7 = 28 with algebra tiles.

Accepted Answer

Put 3 -x's and 7 +'s on one side and 27 +'s on the other. Take away 7 +'s from both sides, then split the remaining +'s into each x. Flip both sides to change -x to x.

Answer

Put 3 -x's and 7 +'s on one side and 27 +'s on the other. Split the 27 +'s into each x, then take away 7 +'s from each side.

Question 8

Choose three expressions that match the algebra tiles model shown. The preferred method is to understand that the model shows three (3) groupings of (3x-2) ... and select the expression that can be simplified using distributive property. Then simplify it to find another matching expression. Finally...choose a large expression that literally spells out each of the three groups...it will have 6 terms. In a pinch...well...three of the expressions should evaluate to equal values...choose x=9 and find the three that evaluate to the same value using Desmos.

Accepted Answer

$$3x-2+3x-2+3x-2$$
