Answer=8.6c+13

Meg earns $5.40 per car and $5 in tips. Given the information, Meg's earnings can be shown in the expression '5.40c+5'

Rich earned 3.20 per car and $8 in tips. Given the information, Rich's earnings can be shown with the expression '3.20c+8'

Now lets put the expressions together to see how much they made all together...

5.40c+5+3.20c+8
add 5.40c and 3.20c
8.60c+5+8
add 5 and 8
8.60c+13
or
8.6c+13

27. Which expression is NOT equivalent to the other expressions?
Dahasolnce [82]

Answer:

C.

Step-by-step explanation:

Choice A:

(4x^2y)^2=(4x^2y)(4x^2y)=(4 \cdot 4)(x^2 \cdot x^2)(y \cdot y)=(16)(x^{2+2})(y^{1+1})=16x^{4}y^{2}

Choice B:

16x^4y^2 appears exactly the same as choice A simplified.

Choice C:

16x^2y^4 is not the same as A or B since x doesn't have power 4 and y doesn't have power 2.

Choice D:

4^2x^4y^2=(4 \cdot 4)x^4y^2=16x^4y^2 is the same as A and B.

So the only odd ball is C.
