13 A group of three friends order a combo meal which
includes two slices of pizza
and a drink. Each drink is
priced at $2.50. If the
combined total is $31.50, how
much is the cost of a slice o
pizza?

Step-by-step explanation:

if I understand correctly, then the 3 friends ordered a combo meal each.

so, 3 drinks and 3×2 = 6 slices of pizza are ordered.

and that costs in total $31.50.

each drink costs $2.50.

so, the calculation is (with x being the price of a pizza slice) :

3×2.5 + 6x = 31.5

7.5 + 6x = 31.5

6x = 24

x = 4

so, each slice of pizza costs $4.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
