Answer:
x= 27
Step-by-step explanation:
a triangle always has 180 degrees, therefore:
(3x-17)+(x+40)+(2x-5)= 180
6x+18=180
6x=162
x=162/6
x=27
j=2
Step-by-step explanation:
take the second numbers in each parentheses and subtract them. put this answer on top of a fraction
(j,3) (8,2)
2-3 = -1
take the first numbers and subtract. put this answer at the bottom of fraction
8 - J = 6
j = 2
answer should equal -1/6
the formula for a slope is y2-y1/x2-x1
look at the points like this, and fill in the places with the numbers and j they give you
(X1,y1) (X2,y2)
The least common denominator is: 60
Then comparing 100/60 with 100/60
<span>100/60 = 100/60,
therefore,
20/12 = 25/15</span>
