WORTH 35 POINTS :)) 13. What is the sum of the solutions of the 2 equations
below?
8x = 12
2y + 10 = 22

A. 23
B. 7
7 1 / 1
C. 9
D. 10
E. 173

7.5

Step-by-step explanation:

8x÷4=12÷4

2x=3

x=3/2=1.5

2y+10=22

2y=12

y=6

1.5+6=7.5=7½

7.5 or 7½

Step-by-step explanation:

8x = 12

x = 12/8 (12/4 / 8/4)

x = 3/2

x = 1.5

2y + 10 = 22

2y = 12

y = 6

1.5 + 6 = 7.5 = 7½

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
