Solve for x: 3(x + 1) = −2(x − 1) − 4
Anika [276]
Solve your equation step-by-step.

3(x+1)=−2(x−1)−4


Simplify both sides of the equation.

3(x+1)=−2(x−1)−4

Simplify:

3x+3=−2x−2

Add 2x to both sides.

3x+3+2x=−2x−2+2x

5x+3=−2

Subtract 3 from both sides.

5x+3−3=−2−3

5x=−5

Divide both sides by 5.

5x/5 = −5/5

x=−1

24.5 is 33 1/3% of what number?
julia-pushkina [17]

Answer: 73.5

Step-by-step explanation:

The percent <em>33 1/3% </em>represents 1/3 of 100%. We can multiply 33 1/3% by 3 and get 100%. We need to find what 24.5 is 33 1/3% of.

Since 1/3 x 3 = 100%, then 24.5 x 3 must equal the number we're trying to find.

24.5 x 3 = 73.5.

Therefore, 24.5 is 33 1/3% of 73.5. I hope this helps, and good luck!
