Answer:
See below
Step-by-step explanation:
Here is how to start....you didn't include the equations in question, so I do not know what the answer may be
solve for x
y-10 = 5 x^2 divide thru by 5
(y-10)/5 = x^2 'sqrt' both sides
± sqrt( (y-10) / 5 = x change x's and y's
± sqrt ((x-10)/5) = y
Answer:
16
Step-by-step explanation:
Let's take a look.
So we have 3*2*2*2*2=48 glasses
if half used 2 and other half used 1... we have a sum of 2+1=3
so 48/3 = 16
