I'm going to have 3 more of these on my page HELP PLSS ​

1. B

2. A

3. I

4. F

Step-by-step explanation:

1. 8x +15 = 7

minus 15 from 7

8x = -8

divide by 8

x=-1

2. 12x -42 = 18

add 42

12 x = 60

divide by 12

x=5

3. 15 +8x = 47

minus 15

8x = 32

divide by 8

x=4

4. 17 -4x =33

minus 17

-4x = 16

divide by -4

x= -4

1 is B. X=-1

2 is A. X = 5

3 is I. X=4

4 is F. X =-4

Hope it helps

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
