4.2%x = 2.5
Please explain how to do this ^^ Thanks
4.2%x = 2.5
First, change the percent to a decimal.
4.2% = 0.042
0.042x = 2.4
Divide both sides by 0.042
x = 2.4 / 0.042
x = 57.143
0.042x = 2.5
Divide both sides by 0.042
x = 2.5 / 0.042
x = 59.52
To solve the equation 4.2%x = 2.5, you need to isolate the variable x and determine its value. Here's a step-by-step explanation of the process:
Step 1: Convert the percentage to a decimal form:
To convert the percentage 4.2% to decimal form, divide it by 100:
4.2% = 4.2/100 = 0.042
So, the equation becomes 0.042x = 2.5.
Step 2: Isolate the variable x:
To isolate x, divide both sides of the equation by 0.042:
(0.042x)/0.042 = 2.5/0.042
This simplifies to:
x = 2.5/0.042
Step 3: Calculate the value of x:
Using a calculator or performing the division operation manually, divide 2.5 by 0.042:
x ≈ 59.52
So, the value of x is approximately 59.52.
Therefore, the solution to the equation 4.2%x = 2.5 is x ≈ 59.52.
