Answer:
1 3/4 or 1.75
Step-by-step explanation:
An easy way to do this is to convert to decimals
1/4 = 0.25
2/4 = 0.5
3/4 = 0.75
Now, for the numbers for this problem.
2 3/4 would be equal to 2.75
3 1/2 would be equal to 3.5
Add those two numbers together and you get 6.25
Subtract that from 8 and you get 1.75 or 1 3/4
Answer:
1. 8.5 yards.
2. $42.5
Step-by-step explanation:
We have been given that Sue buys 5 pieces of fabric. Each piece is 
yards long.
1. To find the total length of fabric bought by Sue we will multiply length of each fabric piece by 5.
Therefore, Sue bought 8.5 yards of fabric.
2. 1 yard of fabric costs $5.
So 8.5 yards of fabric will cost : 5*8.5
Therefore, the cost of total fabric bought by Sue is $42.5.

Answer:
8 cm
Step-by-step explanation:
4+4=8 To get the diameter, double the radius and add them together.
4x+3y=7
3x-2y=9
12x+9y=21
12x-8y=36
^^Multiply top equation by 3 and multiply bottom equation by 4
12x+9y=36
- 12x-8y=36
17y=-15
^^Then subtract those two new equations
17y/17= -15/17
Y= -0.88
^^Next divide both sides by 17
4x+3* -0.88=7
4x + (-2.64) =7
-(-2.64) -(-2.64)
4x = 9.64
4x/4=9.64/4
X=2.41
^^then choose on equation and put your new y in the y spot and solve.
X=2.41
Y=-0.88
Your point/coordinate is (2.41,-.88)
