Answer:
The perimeter is 52
Step-by-step explanation:
Just add all the numbers together
13 + 9 + 3 + 7 + 5 + 15 = 22 + 10 + 20 = 32 + 20 = 52
18 * 5 = 90
90 represents 100%, because there are 5 20% in 100%
In total there are 90 club members
80% = 71 do not have birthdays in the summer.

w=-30÷5
w=-6
Look at the gradient of both the equations (the x multiplier, usually known as m), and there are a couple of rules:
Parallel: The gradients are identical
Perpendicular: Look at the gradients as fractions. To get the perpendicular to a gradient you flip the fraction and change the sign. If this is the case for the two gradients, then they are perpendicular.
