Answer:
No
Step-by-step explanation:
the line has to be straight for it to be a proportional relationship..
Answer:
grams cause its is really small
So the equation would be 52/x (x being the number of total number of 7th graders) and 26/100 (100 being 26% out of 100%).
You do cross multiplying which would be 52/x = 26/100 ------ 5200 = 26x
You divided 26 by both sides.
5200/26=200
There are 200 7th graders total.
This is a lot of calculation.
So we know that the sum of angles for any heptagon is 900, because heptagon can be divided into five non-overlapping triangles and sum of angles of each triangle is 180.
Now you just add up all angles and simplify the equation:
900 = (6x - 8) + 120 + (7x - 64) + (5x - 4) + 135 + (3x + 31) + (4x + 15)
900 = <span>25x + 225
Now it's just regular algebra equation. You can solve for x:
675 = 25x
x = </span>27
So the value of x is 27
