Answer:
x = 30 ∠A = 132 degrees
Step-by-step explanation:
Set the equations equal to each other to solve for x
5x - 18 = 3x + 42
-3x - 3x Subtract 3x from both sides
2x - 18 = 42
+ 18 + 18 Add 18 to both sides
2x = 60 Divide both sides by 2
x = 30
Now plug this into the equation for angle A
∠A = 5(30) − 18 Multiply
∠A = 150 - 18 Subtract
∠A = 132 degrees

Answer:
4:3,12:9, and 16:12
Step-by-step explanation:
Equation y = 5x - 27.95
Plug in 34 for x
5(34) - 27.95
170 - 27.95 = $142.05
Answer:
3/20
Step-by-step explanation:
Total number of students = 15 + 10 = 25
Number of girls = 10
Number of ways to select 2 students =
Number of ways to select 2 girls =
Compute the probability of selecting two girls as follows:
Thus, the probability that both students are girls is 0.15.
0.15 simplified in fraction from: 3/20
