Answer:
18
Step-by-step explanation:
when there is a - in front of an expression in parentheses, change the sign of each term in the expression
6+14+(-2)
then calculate the sum or difference
6+14-2= 18
If I read that right:
(3/5)/(-4/9) is equal to
(3/5)*(9/-4)
-27/20
-1 7/20
Set the equations equal to each other and solve for the variable x. then use the answer from x and plug it in to the equations and you should get an answer
3x=63
63÷3=x
21=x
x=21
that is the value of x
73 is the answer to the top equation and the bottom equation in the triangle. Meaning the equations are equal to each other when you have 21 plugged in for the variable x.
make sure to put your label if it asks for it. it means the book or the teacher. go by what the teacher says if it is different from what the book says
I agree with your answer "supplementary". The two angles combine to form 180 degrees, aka a straight angle
Your teacher seemed to have made a typo.
