Step-by-step explanation:
Answer:
x = 3
y = 3/2
Step-by-step explanation:
look at the hangers to form an equation:
x + x + x + 3 + 3 + 3 = x + x + y + y + y + y
simplify
3x + 3 = 2x + 4y
x + 3 = 4y
x = 4y - 3
you also know that
x + x = y + y + y + y
2x = 4y
substitute x = 4y - 3 into this equation ^
2x = 4y
2(4y - 3) = 4y
8y - 6 = 4y
4y = 6
y = 6/4
y = 3/2
2x = 4y
2x = 12/2
2x = 6
x = 3
M(h)=5h
that is marcia's number of candles where she makes 5 candles per hour (h)
kevin makes 4 but already did 7 so
k(h)=4h+7
when will they have same numbre of candles?
when will m(h)=k(h)
set equal
5h=4h+7
minus 4h from both sides
1h=7
answer is 7 hours
system of equation is
m=5h
k=4h+7
find what value of h makes m=k true
answer is 7 hours
