Answer:
Step-by-step explanation:
First, rewrite the given equation in the form of y=mx+c.
m is the gradient while c is the y-intercept.
3x-5y=8
5y= 3x -8
Thus, the gradient of the given equation is ⅗.
The product of the gradients of perpendicular lines is -1.
(gradient of line)(⅗) = -1
gradient of line= -1 ÷⅗
gradient of line= 
To find the value of c, substitute a coordinate.
When x=3, y=7,
7= -5 +c
c= 7+5
c= 12
Hence, the equation of the line is .
Step-by-step explanation:
a =45°
b=45°
c=30°
d=30°
e=30°
f=30°
total of the angle
90×4=360
We know how we got 90, since a right angle is 90 degrees,
180 degrees are in a triangle.
180-90=90
Find the pair that equals 90 so you get 180 degrees!
If you have more questions don’t have hesitation to ask!
Or add all number to get 180 degrees!
Answer: No two students ran same distance
Step-by-step explanation:
Given
Stacy ran 
of a km i.e.
Jules ran 
of a km i.e.
Raul ran 
of mile i.e.
So, no two students ran the same distance.
