Angles in a triangle always add to 180 degrees. 180=(8x+3degrees)+(10x-4 degrees)+91
180-91=89 89=(8x+3 degrees)+(10x-4 degrees) 89-3= 86 86+4=90
(8x+10x=18x) 18x=90
divide bothe sides by 18
x = 5
The answers are "EN and ZW" and "CV and LR"
Parallel lines can be described as being like the two L's in parallel. Because they are both going in the same directions and have the same slope, they will never touch even if you extended them to infinity.
The number with the same value as 28 tens is 280.
It's a nonlinear because the x and y values are not increasing at the same ratio each time. This would be an example of a linear function:
x l 1 2 3 4 5 6
y l 3 6 9 12 15 18
As x increases by 1, y increases by a multiple of 3
First add the seconds you have 45 +5+10 seconds which equals 60 seconds or 1 minutes. Now add the minutes 9 + 7 + 12 minutes = 28 minutes then add that 1 minutes that you got from the seconds 28 + 1 minute = 29 minutes 7:40 + 20 minutes = 8:00 + 9 minutes = 8:09 am. So Marsha arrived to school at 8:09 am. Comment if you have any questions.
