Substitution
y = 2x - 12
y = -x + 3
-x + 3 = 2x - 12
+ x + x
-----------------------------
3 = 3x - 12
+ 12 + 12
-----------------------
15 = 3x
------ ------
3 3
x = 5
y = 2(5) - 12
y = 10 - 12
y = -2
The final answer is (5,-2).
6.25t + 8 = 12.5t + 13
Subtract 8 from both sides
6.25t = 12.5t +5
Subtract 12.5t from both sides
-6.25t = 5
Divide -6.25 by both sides
t = 0.8
Answer: -11/20
Step-by-step explanation:
1/5-3/4= 4/20-15/20= -11/20
Answer:
40
Step-by-step explanation:
Given:
Initial number of members = 600
Percentage of women = 
Now, members added = 200
So, total number of members after addition = 600 + 200 = 800
Percentage of women out of 800 members = 
Increase in women = New number of women - Old number of women
Therefore, increase in women = 400 - 360 = 40
So, 40 women are there in the 200 new members that joined the club.
