Answer:
Step-by-step explanation:
line up your givens like this:
1, 575 visitors 100%
? adults 56%
? teeenagers 16%
? children. 28%
cross-mulyiply
adults*100 = 1,575*56
teens*100 = 1,575*16
children*100 = 1,575*28
divede each side by 100
adults= 1,575*56/100
teens = 1,575*16/100
children= 1,575*28/100
solve
adults= 882, teens = 252, children= 441

Answer:
(x-8)/(4x-4) x ≠ 1 or 8
Step-by-step explanation:
Common factors can be cancelled, but cannot be ignored when it comes to determining where the function is undefined.
The function is undefined for x=1 and x=8, the values of x that make the original denominator zero.
It would be 5 months until the price for the notebook computer would be the same. Here are the steps to solving the problem:
1. Step up the equation, 200 + 10x = 100 + 30x
2. Subtract 100 from both sides and Subtract 10 from both sides,
100 - 200 = 10x + 30x, 100 = 20x
3. Solve for x, 100/20 = 20x/20, x= 5
Answer:
x would equal 8, not sure but I think y would be 16
