Answer:
Step-by-step explanation:
The slopes of parallel lines are equivalent, so you are correct.
Answer:
∠CGA or ∠DGF
Step-by-step explanation:
Supplementary angles add up 180°
∠CGD + ∠CGA = 180°
∠CGD + ∠DGF = 180°
Answer:
A unit rate is a rate with 1 in the denominator.
Step-by-step explanation:
Answer:
rearrange them properly to get
x-y=7
-3x+y=12
( by elimination method)
x-y = 7
-3x+y=
(x+ –3x) + (–y+y) = (7+12)
-2x+0= 19
x= -9.5
from eqn(i)
x-y=7
-9.5 - y=7
-y=16.5
y= -16.5
16x - 4 + 58 + 9x - 6 = 180
25x + 48 = 180
25x = 132
x = 5.28
