The correct answer is: D) Subtracted like terms incorrectly
Step-by-step explanation:
Given
The terms 11.2y-7.4y need to be subtracted. But option b is to add them. We will add them and then solve the equation to see if its right.
So adding 11.2y-7.4y
Dividing both sides by 18.6
so by adding the terms instead of subtracting we get y=7.6.
this means that the error was adding 7.4y-11.2y instead of subtracting
The correct method will be:
Dividing both sides by 3.8
Hence,
The correct answer is: D) Subtracted like terms incorrectly

Answer:
5
Step-by-step explanation:
These are functions, the number in the parentheses shows you what number you will replace x with
If f(x) = x + 3, then f(-1) is -1 + 3
So, -1 + 3 = 2. g(2) = 2(2) + 1 = 4 + 1 = 5
Hope this helps friend.
Answer:
1. 8.3%
Step-by-step explanation:
Relative error = absolute error/expected measurement
The expected measurement is given as 6 ft.
Now, the absolute error is usually equal to half of a unit of the measure.
This means the absolute error in this case is ½ × 1 = 0.5 ft
Thus, the exact measurement will be;
6 ± 0.5
Thus;
Relative error = 0.5/6
Relative error = 0.083
Expressing it in percentage gives 8.3%
