Multiply each equation by a constant that would help to eliminate the y terms. 2x-5y=-21 3x-3y=-18 What are the resulting equati

anyanavicka [17]

Answer:

6x - 15y = -63

15x -15y = -90

Step-by-step explanation:

We need to multiply the two equations by a constant that will eliminate the y terms.

The two equations are:

2x - 5y = -21

3x - 3y = -18

Let us multiply the first by 3 and the second by 6. The resulting equations will be:

6x - 15y = -63

15x -15y = -90

Note: To solve the system of equations we can simply subtract the first from the second.

A train left for London, and after 9 hours later, a car traveling 80 miles per hour tried catching up to the train. After 3 hour

morpeh [17]

Answer:

20 miles per hour

Step-by-step explanation:

Given that the train left for London, and after 9 hours later, a car traveling 80 miles per hour tried catching up to the train. After 3 hours, the car caught up

Which means that the car travelled the same distance in 3 hours as the train travelled in 9 + 3 = 12 hours

Let the distance be d

Given the speed of car is 80 miles per hour

We know that $speed=\frac{distance }{time}$

$80=\frac{d}{3}$

d = 240 miles

Now for the train Average speed = total distance / total time taken

Average speed of the train = $\frac{240}{12}$ = 20 miles per hour
