The answer is B
I know this because 8 divided by -4 =-2
Therefore the answer is: B
Answer:
x = 80
Step-by-step explanation:
∡KJL = 180 - (60 + 40)
∡KJL = 80
∡XJK + ∡KJL = 180 (they are a linear pair of angles)
x + 20 + 80 = 180
x + 100 = 180
x = 80
Answer:
$840
Step-by-step explanation:
First, add 30 to 10.
Then, multiply your answer (40) by 21.
Finally, you get your final answer of $840.
Answer:
x=5, y=6. (5, 6).
Step-by-step explanation:
-6x+6y=6
-6x+3y=-12
---------------
simplify -6x+6y=6 into -x+y=1 and y=1-(-x)=1+x
-6x+3(1+x)=-12
-6x+3+3x=-12
-3x=-12-3
-3x=-15
3x=15
x=15/3
x=5
-6(5)+6y=6
-30+6y=6
6y=6-(-30)
6y=6+30
6y=36
y=36/6
y=6
