The value of percent error of the odometer is, 12%.
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
We have to given that;
The odometer recorded 13.2 miles for his last trip to the hardware store.
But he knows the distance traveled is 15 miles.
We know that;
The percent error = (Measured value - Actual value) / actual value × 100
Here, The actual value = 15 mile
And, The measured value = 13.2 mile
So, The percent error is,
⇒ Percent error = |13.2 - 15| / 15 × 100
= 1.8/15 × 100
= 12%

12 percent is the error.

7x, because 12x − 8x + 3 = 4x + 3 = 7x
12x − 5, because 12x − (8x − 3) = 12x − 5
x, because 12x − 8x + 3 = 12x − 11x = x
Answer:
A. 3 + 4x, because (12x − 8x) + 3 = 4x + 3 = 3 + 4x.
Step-by-step explanation:
12x − 8x + 3 is equal to 3 + 4x.
1.5 miles/ .6 hours = 2.5 miles per hour
her walking rate is 2.5 miles per hour
d= r * t
4.5 miles = 2.5 * t
divide each side by 3.5
4.5 /2.5 = t
1.8 = t
t = 1.8 hours
11 am - 9 am = 2 hours
She will make it to work on time because 1.8 hours < 2 hours
