Two algebra questions!: (

1)given v = 2πr2h, solve for h

a)h = v/2r2

b)h = v2πr2

c)h = v - 2πr2

d)h = v/2πr

2)solve the equation for y: -8x + 4y = 20
a)y = 2x - 5

b)y = 2x + 5

c)y = 1/2x + 5

d)y = 1/2x + 20

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
