Answer:
Step-by-step explanation:
Exterior angle of polygon = 360/n
9° = 360/n
n = 360/9
n = 40
Answer:
24
Step-by-step explanation:
just multiply 5 times 18 and gives u 90 and then add all the other numbers and het 66 90 m-66=24 all that added equals 90 90 divided by 5 is 18
The maximum weight on a roller coaster is 400 pounds (Max = 400).
If your friend weighs 120 pounds (y = 120), what is the most you can weigh so you can ride together (x + y < 400).
x + 120 <_ 400.
y = 120
Subtract 120 from both sides.
x <_ 280.
You can weigh at most 280 pounds (x <_ 280).
I hope this helps!
We let x = Kim's amount
y = Laura's amount
z = Molly's amount
We have three unknowns and it should be that we have three equations to set up to be able to solve this.
x + y + z = 385 (1)
z - x = 105 (2)
2/5 = x/z (3)
Solving simultaneously, we can get the values as follows:
x = 70
z = 175
y = 140
Therefore, the percentage that Laura got was 36.4% of the whole money. Hope this answers the question.
