Answer:

If 2 mph) 5 hours

If 2.5 mph) 4 hours

If m mph) 10/m hours

If m+2 mph) 10/(m+2) hours

If m/3 mph) 30/m hours

Step-by-step explanation:

To find the time divide the distance (10) by the speed.

10/2=5

10/2.5=4

10/m

10/(m+2)

10/(m/3)=10(3/m)=30/m

Thepotemich [5.8K]

Answer:

The two linear equation

x + y = 19.... Equation 1

0.55x + 0.75y = 12.65... Equation 2

Nedra purchased

9 Apples and 11 Oranges

Step-by-step explanation:

Nedra purchased apples and oranges at the grocery store. which two linear equations can be used to find the number of apples and oranges?

Let the number of apples be represented by x

The number of oranges by represented by y.

Hence,

Apples are $0.55 each and oranges are $0.75 each. If she spent a total of $12.65 for 19 pieces of fruit,

Hence:

x + y = 19..... Equation 1

x = 19 - y

$0.55 × x + $0.75 × y = $12.65

0.55x + 0.75y = 12.65.....Equation 2

Hence: we substitute 19 - y for x in Equation 2

0.55(19 - y) + 0.75y = 12.65

10.45 - 0.55y + 0.75y = 12.65

-0.55y+ 0.75y = 12.65 - 10.45

0.20y = 2.2

y = 2.2/0.20

y = 11 oranges

x = 19 - y

x = 19 - 11

x = 8 Apples

Maya drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 12 hours. When Maya drove
Roman55 [17]

Answer:

480 miles.

Step-by-step explanation:

Let x represent the distance between Maria's house and mountains ans r represent Maria's rate for going trip.

We have been given that there was heavy traffic on the way there, and the trip took 12 hours.

\text{Distance}=\text{Rate}\times \text{Time}

x=12r

We are also told that hen Maya drove home, there was no traffic and the trip only took 8 hours. Maria's average rate was 20 miles per hour faster on the trip home.

So Maria's speed while returning back would be r+20.

x=8(r+20)

Upon equating both distances, we will get:

12r=8(r+20)

12r=8r+160

12r-8r=8r-8r+160

4r=160

r=\frac{160}{4}

r=40

Upon substituting r=40 in equation x=12r, we will get:

x=12r\\\\x=12(40)\\\\x=480

Therefore, Maya live 480 miles away from the mountains.
