Answer:
C = 15
Step-by-step explanation:
Let A = # of adults and C = # of children.
A + C = 20
15A + 10C = 225
There are several ways to solve this system; here is one of them.
From the first equation: C = 20 - A
Substitute into the second equation: 15A + 10(20 - A) = 225
Multiply, collect terms, and subtract 200 from each side: 5A = 25 => A = 5
Since C = 20 - A, C = 15
"0.5 ft * 12 = 6 inches (because there are 12 inches in 1 foot)1 day = 24 hours0.5 ft per day = 6 inches in 24 hoursInches grown in one hour = 6/24 = 0.25"
Answer:
-14x^4+4x^3-6xy^3
Step-by-step explanation:
prime factor stuff.. 32 = 8*4 = (4*2)*(2*2) = (2*2*2)*(2*2)
3 √(2*2*2*2*2*x*x*x*x*z) = 3 √(2²*2²*2*x²*x²*z)
It's a square root so move one of each pair outside the radical.
3*2*2*x*x √(2*z)
12x² √(2z)
