Answer:
7 chocolate bars will cost $35
Step-by-step explanation:
if 3 cost $15 then 1 bar would cost 5 dollars and 5x7=35
here is a ratio:
<u>3</u> = <u>7</u>
15 = 35
Ratio of girls to boys is 3:2....added = 5.....this means that 3/5 of the total students are girls and 2/5 of the total students are boys.
so if there are 50 students...
3/5(50) = 150/5 = 30 girls
2/5(50) = 100/5 = 20 boys
There are 13 angles.
We know that

and

(11 angles)
1.

(9 angles)
2.

(8 angles)
3.

(7 angles)
4.

(6 angles)
5.

(5 angles)
6.

(4 angles)
7.

so we have a parallelogram.

(3 angles)

(2 angles)
8.

(1 angle)
