Answer:
15 feet = Length
Step-by-step explanation:
The area of a rectangle is:
Area = Length x Width
The Area is given as 180 square feet (ft2) and the width is given as 12 feet. Let's plug those values into the Area formula to find the length:
Area = Length x Width
180 = Length x 12
Divide both sides of the equation by 12:
180/12 = Length
15 feet = Length
Answer:
1.645 ft

Divide the length of the board by the number of pieces it will be cut into
8.225/5=1.645 ft
Answer:
The original price of the laptop is 840
Step-by-step explanation:
Here, we want to calculate the original price of a laptop, given the amount that was paid off and the discount percentage enjoyed.
Firstly, let’s add back the 50 taken off. That makes a total of 50 + 664 = 714
Now, we remember he was also given 15% off. Let the price paid be x;
The 15% of x is equal the difference between x and the 714
Thus;
15/100 * x = x - 714
15x/100 = (x-714)
15x = 100(x-714)
15x = 100x -71400
100x-15x = 71400
85x = 71400
x = 71400/85
x = 840
