Answer: Subtraction Property of Equality
Step-by-step explanation:
- the subtraction property of equality is the rule that when you subtract the same number to or from both sides of an equation and get an equivalent equation
__________________________________________________________
- for this equation you would subtract 5.2 from the left-side of the equation and subtract it from 35.2 on the right side of the equation
- this is to isolate n
- basically 2.5n = 30 since n is a variable and that number multiplied by 2.5 will equal 30
- so the new equation would be 2.5n = 30
- so then: =
so n = 12
hope this helps :)

Answer
Find out the what is the percent error in the measurement, to the nearest tenth of a percent .
To prove
Formula
Where error = | Approx - Exact |
As given
Karen measures the width of a garden plot and records that it is 44.25 meters. Its actual width is 45.5 meters.
Approx value = 44.25 meters
Actual value = 45.5 meters
error = | 44.25 - 45.5 |
= |-1.25|
= 1.25
Put in the formula
Percentage error = 2.7%
Therefore the percentage error is 2.7% .
