Answer:
x = 3
y = 3/2
Step-by-step explanation:
look at the hangers to form an equation:
x + x + x + 3 + 3 + 3 = x + x + y + y + y + y
simplify
3x + 3 = 2x + 4y
x + 3 = 4y
x = 4y - 3
you also know that
x + x = y + y + y + y
2x = 4y
substitute x = 4y - 3 into this equation ^
2x = 4y
2(4y - 3) = 4y
8y - 6 = 4y
4y = 6
y = 6/4
y = 3/2
2x = 4y
2x = 12/2
2x = 6
x = 3
Answer:
x = 15/4
Step-by-step explanation:
x - 9x + 4x = - 15
- 4x = - 15
4x = 15
x = 15/4
We know that 1 meter is 0.001 km and that 1 minute is 60 seconds.
To transform 15m/s we into km/min we have to multiply 15 by 0.001 and multiply it by 60.
- its the answer
On the 40th and the 80th you will receive both a free beverage and a free appetizer. You can find this by simply finding the multiples of both number up to 100 (or a little more than 100) to find out on which dates you'd get bothe an appetizer and beverage for free. Here are the multiples of both, to prove this answer.
- 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104.
- 10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100.
Thus making 40 and 80 the answers. I hope this helps!
