Answer:

x = -2/7

Step-by-step explanation:

3(3 + 2) + 2(x + 1) = -5(x – 3)

Combine like terms

3(3 + 2) + 2(x + 1) = -5(x – 3)

3(5) + 2(x + 1) = -5(x – 3)

15 + 2(x + 1) = -5(x – 3)

Distribute

15 +2x+2 = -5x +15

Combine like terms

2x+17 = -5x+15

Add 5x to each side

2x+5x +17 = -5x+5x +15

7x +17 = 15

Subtract 17 from each side

7x+17-17 = 15-17

7x = -2

Divide each side by 7

7x/7 = -2/7

x = -2/7

lana66690 [7]

<u>Complete Question:</u>

Corinne is taking a train into the city. The train travels at a rate of 45 miles per hour. Which quantity depends on the other?

A. The distance traveled depends on the number of hours traveled.

B. The number of hours traveled depends on the speed of the train.

C. The speed of the train depends on the distance traveled.

D. The speed of the train depends on the number of hours traveled.

<u>Answer:</u>

Corinne is taking a train into the city. The train travels at a rate of 45 miles per hour. The distance traveled depends on the number of hours traveled

<u>Step-by-step explanation:</u>

As we know the velocity can de defined as the rate of change of position of objects in a particular time. The formula is given by,

           \text {velocity}=\frac{\text {distance}}{\text {time}}

Here, in the question, rate of speed of train is given as 45 miles per hour. if we keep the velocity as constant one, then distance is directly proportionate to the travelled time

            \text {distance}=\text {velocity} \times \text {time}

If 'v' is constant,

           \text {distance} \propto \text {time}

By this we can conclude that, the distance travelled by the train depends on the time taken to travel to it. Hence option A would be the correct one.
