which could be the resulting equation when elimination is used to solve the given system of equations?

5a+5b=25
-5a+5b=35

10a = 60
10b = 60
–10a = 60
–10b = 60

Option (2) is correct

10b = 60

Step-by-step explanation:

 Given :  System of equations as

  5a+5b=25

 -5a+5b=35

We have find the resulting equation when elimination is used to solve the given system of equations.

Consider the given system of equations,

5a+5b=25  (1)

-5a+5b=35 (2)

Adding equation (1) and (2) , we get,

5a + 5b + (-5a + 5b) = 25 + 35

Simplify , we have,

5a + 5b -5a + 5b = 60

10b = 60

Thus, 10b = 60 is used to solve the given system of equations using elimination.

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
