Just do 6.3 × 7 × 21. Which is then equal to 926.1^3.

Answer:
In the pics
Step-by-step explanation:
Srry about the messy sketches
hope you got the general idea
if not :
Each figure got it's own sum of its angles. All I did was to sum all the given angles and made it equal to that number(360/540/720).
As a result, I found the value of the variable and after that the angles themselves.
X=number of plates
y=number of cups
4x+5y=25.25
7x+3y=25.50
Add the two equations together:
11x+8y=50.75
11x=50.75-8y
x=
Plug x into the first equation:
4x+5y=25.25
4(
) = 25.25
= 25.25
= 25.25
203-32y = 277.75
-32y=74.75
32y=-74.45
y=2.34 (rounded to nearest hundredth)
The price of a plate is $2.34
2 1/2 = 2.5
12 1/2 = 12.5
This means you can calculate how may times it goes in by dividing it and rounding the number down:
12.5 / 2.5 = 5
*5 can not be rounded down so it stays the same
This means that 2 1/2 goes into 12 1/2 5 times. Hope this helps! :)
