The right answer is Option C.
Step-by-step explanation:
Given,
2/5 cup of coconut shavings covers 1/4 of a cake,
![\frac{2}{5}\ coconut\ shavings=\frac{1}{4}\ of\ cake](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%5C%20coconut%5C%20shavings%3D%5Cfrac%7B1%7D%7B4%7D%5C%20of%5C%20cake)
For one whole cake, we will multiply both sides with 4;
![4*\frac{2}{5}=\frac{1}{4}*4\\\frac{8}{5} = 1\ cake](https://tex.z-dn.net/?f=4%2A%5Cfrac%7B2%7D%7B5%7D%3D%5Cfrac%7B1%7D%7B4%7D%2A4%5C%5C%5Cfrac%7B8%7D%7B5%7D%20%3D%201%5C%20cake)
Writing in simplified fraction form;
![1\ cake = 1\frac{3}{5}\ cups](https://tex.z-dn.net/?f=1%5C%20cake%20%3D%201%5Cfrac%7B3%7D%7B5%7D%5C%20cups)
The right answer is Option C.

Answer:
Perimeter of the board
Step-by-step explanation:
That measurement of "the border of her bulletin board" is actually the PERIMETER of the board.
Yes Suzanne made an error in solving the equation
<h3><u>Solution:</u></h3>
Given that Suzanne did this work to solve an equation did she make an error
Given equation: x - 5 = 3x - 2 - 7 - 5x
Equation by Suzanne: x - 5 = 2x - 9
Yes Suzanne has made error in solving the equation
As per original equation,
x - 5 = 3x - 2 - 7 - 5x
On the right hand side, when we combine like terms of "x" we get,
x - 5 = -2x -2 - 7
x - 5 = -2x - 9
But the Suzzane has got x - 5 = 2x - 9 which is wrong. Since she missed negative sign before 2
<em><u>Rules for adding positive and negative numbers:</u></em>
To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest.
<em><u>Correct form of solving:</u></em>
x - 5 = -2x -2 - 7
x - 5 = -2x - 9
Divide 5460 by 12 and you would get the answer of 455 per hour/ one hour.
