Answer:
x
=
12 and y
=
1
Explanation:
Given equations are:
(1) ------ 1
3
x
−
y
=
3
(2)------
2
x
+
y
=
25
Multiply (1) by 3 to eliminate the fractional part,
(1) ------- x
−
3
y
=
9 ⇒
x
=
9
+
3
y
-------- let this be equation (3)
Now substitute this value of
x
from (3) in equation (2),
(2) --------- 2
(
9
+
3
y
)
+
y
=
25 ⇒
18
+
6
y
+
y
=
25 ⇒
7
y
=
25
−
18 ⇒
y
=
7
7
Therefore,
y
=
1
Substituting this value of
y
in equation (3),
x
=
9
+
3
×
1
x
=
9
+
3
Therefore,
x
=
12
So we have the values of
x and y as,
x
=
12
and
y
=
1

Answer:
38 people have a membership.
Step-by-step explanation:
That's because the bottom row shows how many years they've had the membership.
And the y axis shows how many people or the frequency of people having the membership for that amount of years.
So its a bar graph that shows you how many of the members have had the membership for a set amount of years.
So all you have to do is add up each column,
0-2 years = 6 people
2-4 years = 8 people
4-6 years = 10 people
6-8 years = 8 people
8-10 years = 6 people
6 + 8 + 10 + 8 + 6 = 38
