Answer:
Adult= $24
child= $21
Step-by-step explanation:
first let's create an equation for each one.
Day 1: 7x+8y=168
day 2: 14x+13y=294
By doing so we can either graph and get the points for x,y or we can substitute each (x=0) (y=0) and solve manually.
x-int.= (24,0)
y-int.=(0,21)
Answer:
r=20
Step-by-step explanation:
to get rid of the division part, you multiply 6 each side. now you have r+10=30. to solve, now you subtract 10 from both sides. this gives you r=20 :)
The answer is 3:00 a.m because if u add 15+55 youll get 60 so if u add an hour to 2 u get 3:00
Percent change=change/original times 100
change=20-16=4
original=20
change=4/20 times 100=0.2 times 100=20
answer is 20%
