Since Angle QPS is a straight angle, it equals 180 degrees.
Angles QPR and RPS equal QPS.
Angle QPR + Angle RPS = QPS
(7x-4) + (9x-40) = 180
x=14
the first answer choice, associative property of addition
hope this helps. gl!
Substitute the variable for the value given.
11 - 3m becomes 11 - 3(2)
Now do the order of operations.
11 - 3(2) =
11 - 6 =
5
So, the answer is 5.
Answer: OPTION B.
Step-by-step explanation:
By definition, the slope equals the Rise divided by the Run; then, the slope can be found using the following formula:

Where "Rise" is the vertical change between two points and "Run" is the horizontal change between those two points.
In this case you can identify in the figure that:

Knowing these values, you can substitute them into the formula.
Through this procedure you get that the slope of the ramp is:
