What must be true for lines a and b to be parallel lines? Select four options, m < 1= (4x-10)°
m < 2 = 58°
x = 20
(3x-1)º = (4x-10)
o <1= 58°
(3x-1)º = 58°
x= 19
(3x-1)° + (4x-10)° + m < 2 = 180°

you probably already have the answer but anyways it's b. 15.0

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
