For what ordered pair (a, b) are there infinite solutions (x, y) to the system ; 3ax + 3y=5b, 2x+y=5

The ordered pair is (2,3)

Step-by-step explanation:

we know that

If a system of equations has infinite solutions, then the equations are the same

we have

3ax+3y=5b > equation A

2x+y=5 > equation B

Multiply equation B by 3 both sides

3*(2x+y)=5*3

6x+3y=15 > equation C

Compare equation A and equation C

so

3ax=6x> 3a=6 > a=2

5b=15 > b=3

The ordered pair is (2,3)

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,

r = h.

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
