48 of the pizzas would be cheese because you divide 80 by 5 and get 16 then multiply that by 3 to get 48
Step 1
<u>Find the value of TS</u>
we know that
if PQ is parallel to RS. then triangles TRS and TPQ are similar
so

solve for TS

we have


substitute

Step 2
<u>Find the value of SQ</u>
we know that

we have


substitute

therefore
<u>the answer is</u>
the value of SQ is 
The answer is 5x because when you do the math 12 subtracted by 7 equals 5 then you add the x at the end.
