Which value of x makes the equation 1.25(4x-10)=7.5
Answers
GPT 3.5
To solve for x, we can start by distributing 1.25 to the terms inside the parentheses:
1.25(4x - 10) = 7.5
Multiplying 1.25 by 4x and -10 gives:
5x - 12.5 = 7.5
Next, we can isolate x by adding 12.5 to both sides:
5x - 12.5 + 12.5 = 7.5 + 12.5
Simplifying the equation:
5x = 20
Finally, to find the value of x, we divide both sides by 5:
5x/5 = 20/5
Resulting in:
x = 4
Therefore, the value of x that makes the equation true is x = 4.
1.25(4x - 10) = 7.5
Multiplying 1.25 by 4x and -10 gives:
5x - 12.5 = 7.5
Next, we can isolate x by adding 12.5 to both sides:
5x - 12.5 + 12.5 = 7.5 + 12.5
Simplifying the equation:
5x = 20
