Answer:
45
Step-by-step explanation:
sum of angles of triangle is 180:
2k + k + 45 + 180 then 3k = 135
k = 45
Answer: p*$4 + d*$3 ≥ $24
Step-by-step explanation:
The price P of popcorn is P = $4, the pricec of a drink is D = $3
He only has $24
The equation that represents the number of popcorns and drinks he can buy us:
p*$4 + d*$3 ≥ $24
This means that the maximum amount of money he can spend is $24.
In this equation you can give the value of p or d, and then find the maximum possible value for the other variable.
For this case we have:
To begin we must graph
, for this:
We do
, then:

So, we have the point 
We do
, then:


So, we have the point
We place both points in a coordinate plane and graph the line. Now, we must find the shaded region that identifies the inequality 
We must replace any point located to the left or to the right of the line. If the inequality is met, then the shaded region will be on the respective side.
We substitute the point

The inequality is met, then the shaded region is to the right of the line.
