32/8= 4
so Donald uses the pack of 48 screws a total of 4 times to build 32 desk
48 x 4 = 192
so he used 192 screws total
2x+8y=20;y=2
2x+8(2)=20
2x+16=20
-16 -16
-------------------
2x=4
x=2
The coordinate will be (2,2)! Hope that was helpful :)

Hiya. I'm going to rewrite the second equation.
By subtracting 5x by both sides, I'll be able to have y by itself:
-y=-5x+13
I'm going to then divide both sides by -1 to get:
y=5x-13.
Then, I'm going to plug that equation into the first equation
3x+2(5x-13)=39
Factor:
3x+10x-26=39
Combine like terms:
13x=65
Divide both sides by 13 to get x by itself to get x=5
Plug this back into the equation of y=5x-13
y=5(5)-13 to get y=12
You have a 4.9 percent chance of testing positive. Hope this helped!
