First u have to expand the brackets...
4 x 2z = 8z
4 x 3 = 12
8z + 12 = 12
Then you have to get numbers on one side, and letter on the other...
8z -12 = 12-12
8z = 0
then u have to divide 8z by 8 to find 1z or just z.
z = (0/8) = 0
z=0
Hope this helps :)
Answer:
The answer to your question is: n = 95°
Step-by-step explanation:
The sum of the suplementary angles equals 180°
Then
121 + x = 180
x = 180 - 121
x = 59°
144 + y = 180
y = 180 - 144
y = 36°
The sum of the internal angles in a triangle equals 180°
x + y + z = 180
59 + 36 + z = 180
z = 180 - 59 - 36
z = 85
Finally
n + 85 = 180
n = 180 - 85
n = 95°
Answer:
5 gray bunnies
Step-by-step explanation:
I subtracted 4 from 9 and got 5 as my answer
Answer:
x=5
Step-by-step explanation:
(x - 5)(x - 5) = 0
x-5=0
x=5
