Rewrite the equation for x, and express its value in terms of a. 3/a x - 4 = 20

My name is Ann [436]

For this case, we must clear variable "x" from the given equation, expressed in terms of "a".

We have:

3/a x-4=20

By clearing "x" we have:

Adding 4 to both sides of the equation:

3/a x = 20 + 4

Multiplying by a/3 on both sides of the equation:

x=24a/3

x=8a

So, x=8a

Answer:

x=8a

Which of the following statements represents a mathematical expression?

4vir4ik [10]

A because there is a difference between a expression and equation. Expressions don’t have a equal sign or an answer. But equations have an equal sign and an answer. So because everything else has an answer or equal sign, the correct answer would be A. Hope this helps!
