<h3>Conversion of Fraction</h3>
Let's convert the mixed fraction to improper fraction
So, we would have
- 63/4,
- 61/4,
- 35/2,
- 25/2
- 35/2.
<h3>Working Cost</h3>
Let's sum it up and multiply by the working cost per hour
- The total labor cost is = total hours worked * hourly rate.
This becomes

Answer:
I think it 6 is the answer I don't know I'm not in middle school
There are 5 solutions for this system.
x^2 + 4y^2 = 100 ____1
4y - x^2 = -20 ____2
Add both 1 & 2 together. x^2 gets cancelled
4y^2 + 4y = 80 (send 80 to the other side and divide by 4)
Then equation the becomes : y^2 + y -20 =0
Now factorise the equation: (y+5) (y-4) = 0
Solve for y : y = -5 and y = 4
Using the values of y to find the values of x. From equation 1:
x^2 = 100 - 4y^2 x = /100 - 4y^2 (/ means square root) Replace values of y
y = -5, x = /100 - 4(-5)^2 = /100 - 100 = 0
y = 4, x = /100 - 4(4)^2 = / 100 - 64 = /36 = -6 or 6
Thus we have 6 solutions y = -5, 4 and x = -6, 0, 6
