Answer:
slope is 0
Step-by-step explanation:
X - the cost of one night´s lodging
y - the cost of a meal
3 x + 6 y = 132
3 x + 2 y = 109 / * (-1)
-----------------------------
3 x + 6 y = 132
-3 x - 2 y = - 109
-----------------------
4 y = 23
y = 5.75
3 x + 34.50 = 132
3 x = 97.50
x = 97.50 : 3
x = $32.50
The cost of one night´s lodging is $32.50.
7.8 + n = 38.2
n = 38.2 - 7.8
n = 30.4

Answer:
1020 in a day
Step-by-step explanation:
8 men will earn 8/3 what 3 men earn, so will earn ...
