Rectangle diagonals are equal.
2(5a+1) = 2(a+1)
10a + 2 = 2a + 2
10a -2a = 2 - 2
8a = 0
⇒ a = 0
AC = 2(5a+1) = 2(5 × 0 +1)= 2(0 + 1) = 2 × 1 = 2 <span>
</span>BD = 2(a+1) = 2(0 + 1) = 2 <span>× 1 = 2
</span>
Ansver: AC = BD = 2
Well this is pretty easy.
If there are 8 people, with 6 doughnuts in every box, then do 6*4 to give you 24.
If you know you multiplication (recommend practicing), then you would know that 8 is a multiple of 24. So the second step to this word problem is 24/8 to give you the final answer of:
3 doughnuts / person
To solve this problem you must apply the proccedure shown below:
1. You have that :
-The <span>estimate from the moving is $675 for 6 hours of packing and 5 hours of moving.
- </span>The cost will decrease to $425 for 4 hours of packing and 3 hours of moving.<span>
x: rate for packing.
y: rate for moving.
6x+5y=675
4x+3y=425
2. When you solve the system of equations shown above, you obtain:
x=50
y=75
Therefore, the answer is: $50 (Rate for packing) and $75 (Rate for moving).

The answer to this is 253.2 cups
