Answer:
x=12
Step-by-step explanation:
2x-8=16(add a to both sides)
2x=24(divide by 2)
x=12
Answer:
21 to 28
Step-by-step explanation:
15:20
Divide each side by 5
15/5 : 20/5
3:4
we want to find the one that is 3:4
5 to 10 Divide by 5 5/5 to 10/5 1 to 2
18:25 this does not simplify
21 to 28 divide by 7 21/7 to 28/7 3 to 4
24:30 divide by 6 24/6: 30/6 4:5

Step-by-step explanation:
Answer:
The equation is
x =
Step-by-step explanation:
The Equation is formed from two sides equal to each other
- In the algebraic statement "is" means equal
- In the algebraic statement "of" means times (×)
∵ One eighth means 
∴ Negative one eighth means 
→ Assume that the number is x
∵ "of" means times
∴ Negative one eighth of a number =
× (x)
∴ Negative one eighth of a number =
x
∵ Negative one eighth of a number is 
→ "is" means equal, so the left side is
x and the right side is 
∴
x =
⇒ Equation
∴ The equation is
x =
