Angles in a triangle add up to be 180 degrees. 2x+3x+5x= 180
10x=180
x=18
2(18) = 36
3(18) = 54
5(18)= 90

zero
Step-by-step explanation:
Answer:
Total interest is $74.55
Total payments $1574. 55
Step-by-step explanation:
The given regression shows the relationship between the numbers of car washed(x) and the amount earned for charity(y).
y = 10x + 20
We are to calculate the amount of charity if 50 cars are washed. Number of cars are represented by x, so by substituting x = 50 in above equation we can find the amount of charity that is earned by washing 50 cars.
y = 10(50) + 20 = $ 520
Thus, the charity can earn $520 if 50 cars come in for a wash.
