Question

Which equation is true when x = 1/2 ? A. 6 ÷ x = 3 B. 8 x = 16 C. x + 2 = 1 D. 10 ÷ x = 20

Answer 1

to find you, you need to try each Equation!

A:

6÷ 1/2 =3

6×2=3

12=3

-> a is false

B:

8×1/2= 16

8÷2=16

4=16

-> b is false

C:

1/2+2=1

0.5+2=1

2.5=1

-> c is false

D:

10÷ 1/2= 20

10×2=20

20=20

-> d is correct!

Answer 2

Solve for x

Which equation is true when x = 1/2 ?

• A. 6 ÷ x = 3
• B. 8x = 16
• C. x + 2 = 1
• D. 10 ÷ x = 20

Before we determine the equation that has the value of x = 1/2, we will solve each equation in each options and we will prove it.

A. 6 ÷ x = 3

• 6/x = 3
• 6/3 = x
• 2 = x

B. 8x = 16

• 8x = 16
• x = 16/8
• x = 2

C. x + 2 = 1

• x + 2 = 1
• x = 1 - 2
• x = -1

D. 10 ÷ x = 20

• 10/x = 20
• 10/20 = x
• 1/2 = x

Answer:

• Therefore, letter D has the solution of 1/2.
