answer

45 minutes

explanation

using the equation C(m) = 0.1m + 1, C(m) is the cost of the phone call (5.50)

5.50 = 0.1m + 1 subtract 1 from both sides

4.5 = 0.1m divide both sides by 0.1

45 = m

m is the number of minutes, so 45 minutes

James and Aaron run cross country. James has already run 6 miles this month and plans to run 3 miles each day over the next seve

ahrayia [7]

Answer:

Step-by-step explanation:

Step one:

for James

the initial mile covered= 6miles

the planned number of miles per day= 3miles

let the number of days be x

and the total distance in miles be y

the total distance for the x days day will be

y=6+3x------------1

step two:

for Aaron

the planned number of miles per day= 4miles

let the number of days be x

and the total distance in miles be y

the total distance for the x days day will be

y=4x------------2

The system of equations is

y=6+3x--2

y=4x----2

Step three:

for the number of days that Aaron needs to run to meet up with James, we need to equate the two equations to find x which is the solution

6+3x=4x

6=4x-3x

x=6days

This means that Aaron will have to run at 4mile per day consistently for 6 days to meet up with James

A motorist is pumping gas into his car at a rate of 5/12 of a gallon every 1/24 of a minute. At this rate, how many gallons of g

kirill115 [55]

Answer:

5 gallons

Step-by-step explanation:

We can use ratios to solve

5/12 gallon x gallons

---------------- = -------------------

1/24 minute 1/2 minute

Using cross products

5/12 * 1/2 = x *1/24

5/24 = x/24

Multiply each side by 24

24*5/24 = x/24*24

5=x

We can pump 5 gallons
