Witch equation has the solution x=4

C choice.

Step-by-step explanation:

We can either solve the equation or substitute x = 4 to find the true equation.

Solve The Equations

1. 4x=20

Our solution would be x = 5 as we move 4 to divide 20.

2. x/2=8

Our solution would be x = 16 as we move 2 to multiply 8.

3. x+8=3x

Our solution would be x = 4 which is the answer. We basically move x to subtract 3x as we get 8 = 2x.

Then we move 2 to divide 8 as we get x = 4.

4.

We simply multiply the whole equation by 2 to get rid of the denominator.

15.5

step-by-step explanation:

5

∑

n = 1

substitute n = 1, 2, 3, 4, 5 and sum the terms

= + + + 2² + 2³

= 0.5 + 1 + 2 + 4 + 8

= 15.5

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
