Girls : boys = 1:1 girls who sing : girls who do not sing = 1:2
8 girls sing in the show.
How many students are in the show altogether?

48 students

Step-by-step explanation:

Girls who sing : girls who don't sing = 1 : 2

Let total number of girl be x

Part of girls who sing = (1/3)x

Part of girls who sing = 8

                             x = 24

Number of girls = 24

Girls : boys = 1 : 1

Number of boys = number of girls

Total students in the show = 24 + 24 = 48

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
