Answer:

x = 20

y = 30

Step-by-step explanation:

y = 3x - 30

2x + 2y = 100

2x + 2(3x - 30) = 100

2x + 6x - 60 = 100

8x - 60 = 100

8x = 160

x = 20

y = 3(20) - 30

y = 60 - 30

y = 30

Sally wants to fill ten 8-inch tea glasses.how much tea does she need
ra1l [238]
More info is needed.  If you were able to provide the radius of the base of the tea glasses as well as the height (8 inches), then it'd be possible to calculate the volume of one such glass.  Are these short and fat tea glasses?  or tall and slim tea glasses?  My point:  We don't know.  Try to supply the missing info.

There are 10 such 8-inch tea glasses.  Of course you could multiply 10 and 8 to get 80 inches, but 80 inches is NOT a suitable measure of the volume of a liquid.

How to solve r^2/2r^3 step by step please
ZanzabumX [31]
Can't solve this, because it's not an equation.  It's an expression, and I think your goal is to simplify it.

<span>r^2/2r^3 would be better written as 

</span><span> r^2            r^2
------- = -----------       this should be reduced by cancelling "r^2:"
2r^3       2r(r^2)
