Let's find the slope of line passing through given points ~
Hence, slope of the line will be 1.
Since each side is r times the side of ABC, then 30*r+40*r+60*r is the perimeter, which equals 130r (by separating it into r*(30+40+60) using the distributive property)
Answer: 2/5%
Step-by-step explanation: First, convert 0.4 into 4/10. Then, divide the numerator and the denominator by 2. You should get 2/5, which can’t be simplified any more. Voila!
Answer:
168
Step-by-step explanation:
The first equation given is
Where a is number of adult tickets and b is number of student tickets
It is also given that 82 students attended, so we can put "82" in place of "b" and then solve the equation for a:
Hence, 168 adults attended
