Answer: y=3
Step-by-step explanation:
the initial statement is
y
∝
1
x
to convert to an equation multiply by k the constant
of variation
⇒
y
=
k
×
1
x
=
k
x
to find k use the given condition
y
=
15
when
x
=
5
y=kx⇒k=y x=15×5=75
equation is

∣
∣
∣22y=75x22∣∣
when x=25 then
y=75 25=3
Answer:
3/4 as a percent is written as 0.75%
Step-by-step explanation:
A) $644
b) 50%
work:
1,299 - 655 = 644
The answer you are looking for would be 63.
63 is greater than 60, but less than 70, and the tens place (6) is double the ones place (3). Thus meaning 63 is the answer.
I hope this helps!
Answer:
Adult tickets sold: 156
Step-by-step explanation:
Adult ticket: x
Student ticket: y
x + y = 260 ===> -6(x + y = 260) ===> -6x -6y = -1560
6x + 4.5y = 1404 ===> 6x + 4.5y = 1404
________________
add the two equations to eliminate a variable: -1.5y = -156
divide by -1.5: y = 104
substitution to find x:
x + y = 260
x + 104 = 260
x = 156
