The answer is 37. Hope this helps!
Slope is 1/2. The equation to solve it is y2-y1 / x2-x1. I hope you understand it now :)
Answer:
2.5
Step-by-step explanation:
(I'm assuming you're doing this the same way I learned it, if not I'm sorry if it doesn't make sense)
=
Cross multiply
12x=30
Divide
x=2.5
This is just one way to do the problem. An easier way is to simplify the fractions.
=
You can either cross multiply or figure out that 2 is half of four and simply divide 5 by 2 which will also result in 2.5

Answer:
b= 70
Step-by-step explanation:
The sum of the opposite interior angles of a triangle is equal to exterior angle.
a+b = 140
We know that a = b since PQ = RQ The angles opposite the equal sides in an isosceles triangle are equal
b+b = 140
2b =140
Divide by 2
2b/2 =140/2
b= 70
