Answer:
1st formula 2n + 3m = 280
2nd formula 2n + 5m = 320
rearrange 1st formula to equal n:
2n = -3m + 280
n = -3/2 m + 140
rearrange 2nd formula to equal n:
2n = -5m + 320
n = -5/2m + 160
so now you have
-3/2m + 140 = -5/2m + 160
Rearrange to become:
-3/2m + 5/2m = 160 - 140
m = 20
Now place 20 into the very 1st equation in place of the letter m
2n + 3(20) = 280
2n + 60 = 280
2n = 220
n = 110
so it costs $110 per night, $20 per meal
Answer:
Step-by-step explanation:
y - 6 = -5/3(x + 6)
y - 6 = -5/3x - 10
y = -5/3x - 4
Answer:
23
Step-by-step explanation:
All triangles = 180 degrees
65 + 4x + x = 180
65 + 5x = 180
- 65 - 65
----------------------
5x = 115
--- = ----
5 = 5
x = 23
4(23) = 92
F = x = 23
B> 65
92 + 23 + 65 = 180
x = 23
F> = B>
