straight line = 180 degree

example

1) 2w - 24 + 2w - 40 = 180

4w = 180 + 24 + 40

4w = 244

w = 244/4

.......

2) 13n - 11 +(-9 + 12n)

13n - 11 -9 + 12n = 180

25n -20 = 180

25n = 180 + 20

25n = 200

n = 200/25

Answer: The answer is 60

Step-by-step explanation: 40% = .4 because % means hundredths. So 40% = 40/100 = .4

Let x be the total number of marbles.

x = 60 and 24 is 40% of 60 marbles
