Answer:
Step-by-step explanation:
3x + x + 60 = 180.
first, we add the x's together.
4x + 60 = 180
then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.
x + 15 = 45
then, just subtract 15 from both sides, that way we get the variable by itself.
x = 30
also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.
The value 170 000 is 100x larger than the value 170.

Answer:
5 stickers were put in each bag.

Answer:
-2
Step-by-step explanation:
We can find the slope of a line given two points from
m = (y2-y1)/(x2-x1)
= (-2-4)/(1--2)
= (-6)/(1+2)
=-6/3
=-2
