Answer:
5 friends with money left over
Step-by-step explanation:
30/4=7.5
30-8=22
22/4=5.5
So therefore they can bring 5 friends with money left over
Y=78
A polygon has a total of 5 interior angles
In order to find the total amount of angles in a shape you do (the amount of angles - 2)x180 degrees
(5-2(3))180
3x180=540
Add the numbers you know (10+20+30+40+50=150)
540-150=390 and there are 5y altogether so divide 390 by 5 which is 78
<u>x / 5 = y</u>
Multiply each side by 5 : x = 5y
Multiply each side by 2 : <em>2x = 10y</em>
Convention in algebra is that we use letters such as a, b, c, etc., for parameters and letters such as x, y z, and so on, for variables.
Thus the parameters here are a, b and k. k is the constant of proportionality.
Answer:
Yes
Step-by-step explanation:
They are parallel lines basically, ingnore the measurements and the traingle, they were put there to confuse you.
