Darnell's truck can travel 18 miles on 1 gallon of gasoline. How many gallons of gasoline will Darnell need to travel 315 miles? Use the formula d/m=g, where m represents miles per gallon, d is distance traveled, and g is the number of gallons of gasoline used.

Answers

Answer: 17.5 gallons

Step-by-step explanation:

The formula to solve this question will be: g = d/m

where, g = number of gallons of gasoline used

d = distance travelled = 315 miles

m = miles per gallon = 18 miles/gallon

Therefore, the number of gallons of gasoline that Darnell will need to travel 315 miles will be:

g = d/m

g = 315/18

= 17.5 gallons

9 Find the sum of (x + 5), (-4x – 2), and (2x – 1).

Answers

Answer: -x + 2

Step-by-step explanation:

So I assume that the question would be set up like this if you are finding the sum of all 3 terms:

(x + 5) + (-4x - 2) + (2x - 1)

1) Take out parentheses

x + 5 - 4x - 2 + 2x - 1

2) Add like terms

For the x terms:

x - 4x = -3x

-3x + 2x = -x

For the other terms:

5 - 2 = 3

3 - 1 = 2

The sum of the terms is -x + 2

max has 3 5/6 pounds of potting soil. She uses 2 3/8 pounds to fill a pot. how many pounds of potting soil does max have left?​

Answers

Answer:

1 11/24 pounds left

Step-by-step explanation:

For this question, find the common denominators of the fraction to add them.

A common multiple of 6 and 8 is 24.

So, 5*4 = 20  6*4 = 24

3 20/24 of potting soil initially

Then, 3*3 = 9   8*3 = 24

2 9/24 used

To find how many pounds are left:

3 20/24 - 2 9/24 = 1 11/24
