Answer:
A square that has sides of 4.5 units, or a rectangle that is 1 unit wide and 8 units long.
Step-by-step explanation:
First, you need to find the perimeter in the first place. Since there are two sides of the same number, you would double each number.
2 would become 4
6 would become 12
Add 4+12=18
So, our rectangle has to have a perimeter of 18 units. Because a square is a rectangle, you can divide 18 and 4, since a square has 4 sides. You get 4.5. Each side can be 4.5 units.
Or, you can have a rectangle. What I thought first was a length of 9, but I knew that wouldn't work. I drew a rectangle and tried 8. If I put it on the top and bottom, which you need to to find the perimeter, it was only 16. Then I knew I could use 1 as a side length. If you added the sides, it would equal 2, and when you add 16 and 2, it's 18. So, you can use a rectangle that has a length of 8 units and a width of 1 unit.
find the number of miles per 1 liter:
247 kilometers / 19 liters = 13 kilometers per liter.
Divide how may kilometers they want to go by kilometers per liter:
429 kilometers / 13 kilometers per liter = 33 liters are needed.
Answer:
boys : 36
girls : 24
Step-by-step explanation:
60 - 12 = 48
48 ÷ 2 = 24 (girls)
24 + 12 = 36 (boys)
A=1 B=0 C=-18. This will be your correct answer.
