Any
in this set will be real numbers that are both less than
and greater than
. But that's not possible, so this set is empty.
Just divide $100 by 5. 100 divided by 5 = $20 each.
We know that y is equal to x-2. We can just substitute x-2 for y since y is equal to it.
10x- 9(x-2)=24
Distribute.
10x- 9x+18= 24
x+18= 24
Subtract 18 on both sides.
x= 6
Now, plug in x.
y= (6)-2
y= 4
We can check this to see if this works:
4= 6-2, 4=4
10(6)- 9(4)= 24
60-36= 24, 24=24
x=6 and y=4
I hope this helps!

Answer: 10 : t = 16 11 : x = -8 13 : x = 0
Step-by-step explanation: Im sure about 10 and 11 but not too sure about 13 and explanations are too hard for me to explain
Factor x^4-y^4: (x²+y²)(x²-y²)
further factor: (x²+y²)(x+y)(x-y)
so the dimensions are (x²+y²)(length), (x+y) (width), and (x-y) (height)
