Answer:can you give me more detail
Step-by-step explanation:
Let a cup of coffee be represented by = c
Let an omelet be represented by = o
Part A:
The bill at one table for three cups of coffee and five omelets is $7.60.
So equation is : 
...(1)
The bill at another table for one cup of coffee and two omelets is $2.90.
So, equation is : 
...(2)
From equation (2) we get 
.... (3)
Part B:
Substituting the value of 'c' from equation (3) in (1)
As c=2.90-2o
Part C:
Hence, cost of 1 cup of coffee is $0.70
Cost of 1 omelet is $1.10
Answer:
x = 8
Step-by-step explanation:
Step 1: Simplify both sides.
7 - 3x = -2/5x - 69/5
7 + - 3x = -2/5x + -69/5
-3x + 7 = -2/5x + -69/5
Step 2: Add 2/5x to both sides.
-3x + 7 + 2/5x = -2/5x + -69/5 + 2/5x
-13/5x + 7 = -69/5
Step 3: Subtract 7 from both sides.
-13/5x + 7 - 7 = -69/5 - 7
-13/5x = -104/5
Step 4: Multiply both sides by 5/(-13)
(5/-13) * (-13/5x) = (5/-13) * (-104/5)
x=8

Answer: 18 quarts.
Step-by-step explanation: x = ((9) / (3/4)) * (1 1/2)
x = ((9) * (4/3)) * (1 1/2)
x = (36/3) * (1 1/2)
x = (12) * (1 1/2)
x = (12) * (3/2)
x = 18
