The answer of the rotational symmetry is B, (6)
Answer:
For the one including 4w the answer is - 7
The one with n/2 is - 12
Step-by-step explanation:
4w=-13-15
4w=-28
w=-7
Multiply by 2 on both sides
-24=n-12
-24+12=n
Always write it in the variables perspective.
n=-12
Answer:
9
Step-by-step explanation:
225/25= 9

Let w = washer and d = dryer:
w + d = $770,
but w = d + 70, replace w with d+70
(d+70) + d = 770
2d + 70 =770
2d = 770 -70 = 700
and d=$350, then w=350+70 = 420
