Ms. smart's students wrote verbal expressions for the algebraic expression 4x 18 one of the expressions is incorrect. identify the expression that is incorrect, explain why it does not represent 4x-18 and explain why! a) tyler's version: 4 minus 18 times x b) jeff's version: the product of 4 and x decreased by 18 c) ann's version: 4 times x minus i8

Let's start with A (the incorrect answer)

4 minus 18 times x would be:

So 4 - 18x

B reads correctly because the product of 4 and x means we multiply the two together (getting 4x) - and then it says to decrease (or subtract) by 18.

So 4x - 18.

C reads correctly because 4 "times" is the same as multiply by x (which is 4x) and then it says minus 18.

So 4x - 18.

the thermometer is precise but not accurate
