Answer:

The cost of 15 liters is $31.50

Step-by-step explanation:

1. Find the price for 1 liter of petrol.

Divide the cost by the number of liters:

$14.70 / 7 = $2.10 per liter.

2. Multiply the price for 1 liter by the new number of liters, 15.

$2.10 per liter x 15 liters = $31.50

Eighteen increased by x In algebraic expression
Novay_Z [31]

Answer:

18 + x or x + 18

Step-by-step explanation:

Hi there! I'm glad I was able to help you solve this math problem!

We are already given the number eighteen to start with, so this helps us a lot.

Since the word INCREASED means to add, and <u>we're increasing eighteen by x</u>, all you have to do is write it out to get your algebraic expression, as shown:

18 + x

You can also write the expression as x + 18! It doesn't matter what order you write it in.

I hope this helped you! You can comment below if you have any further questions! :)

Question 2 (Essay Worth 10 points)
sashaice [31]
Ryan is correct, the mean is about 8.1.

To find the mean, you have to add up all the values, then divide by the total amount.

For Sample A:
60 x 6 + 90 x 7 + 145 x 8 + 150 x 9 + 55 x 10 = 4050

If you add up all the adults, you have 500.

Dividing 4050 by 500 = 8.1

Sample B will produce a very similar result.
