6/7Y - 18/28 =-15/14
First, let's get a common denominator
24/28Y - 18/28 =-30/28
Move your terms to isolate Y
24/28Y=-12/28
Multiply by 28 on both sides
24/Y=-12
Times both sides by Y, then divide by -12
24/-12=Y
Simplify
-2=Y
I hope this Helps!
Answer:
15 ft
Step-by-step explanation:
Pyramid Volume = (Area of the Base * Height) ÷ 3
Height = 3 * Volume / (Area of Base)
Height = 3 * 216 / 36
Height = 18 cm
<u><em>Answer:</em></u>
A: Stu estimated correctly by rounding up. He ordered enough brick. The exact area is 228.75 square ft
<u><em>Explanation:</em></u>
<u>Since the patio is a rectangle, therefore, we can get the area as follows:</u>
area = length * width
area = 12.5 * 18.3
area = 228.75 ft²
<u>Now, Stu rounded up the values, this means that for Stu's calculations:</u>
the length = 19 ft (rounding up the 18.3 ft)
the width = 13 ft (rounding up the 12.5 ft)
calculated area = 19 * 13 = 247 ft²
We can conclude that Stu was correct when he rounded up as he has ordered enough brick to cover the patio
Hope this helps :)
