That would be y=6 I believe
Answer: There were 40 euros in the drawer at the beginning.
Step-by-step explanation:
When we subtract 6 from 16, we get 10 more ice-creams were sold.
Similarly, we subtract 70 from 120, we get 50 euros was the total selling price of 10 ice-creams.
i.e. Selling price of 1 ice-cream = (50)÷10 =5 euros
Selling price of 6 ice-creams = 6 x 5 = 30 euros
Money in the drawer at the beginning = 70-30 = 40 euros
Hence, there were 40 euros in the drawer at the beginning.
X< -4
You need to do inverse operations and add 12 to both sides.
Answer:
3
Step-by-step explanation:
10x + y = 22 A
2x + y = -2 B
A - B left A - left B = Right A - Right B
10x + y - (2x + y) = 22-(-2)
10x + y -2x -y = 22 + 2
8x = 24
x = 24/8
x = 3
Answer:
Y=3/2x
