X= -2.411

Y= -0.0593

Step-by-step explanation:

Step 1:

Let the given equations be

   2X+3Y= -5 ------------- 1

   5X-Y= -12  --------------2

Multiply 3 in equation 2, we get

15X-3Y= -36  -------------3

Step 2:

On adding equation 1 and equation 3 , we get

       2X+3Y= -5

       15X-3Y= -36

       17X = -41

On solving the above equation, X= -2.411

To get Y value substitute X value in equation 1 we will get

     3Y= -5-2(-2.411)

          = -0.178

     Y = (-0.178)/3

      Y= -0.0593

Gina rides her bike to work at an average of 10.4 miles per hour. She bikes 1.2 hours each day. How many miles does Gina ride ea
tatiyna
So 10.4mi = 1 hour

We need to find out how many miles 1.2 hours is.

1.) Well, the first step would be to multiply 1.2 on both sides of:
10.4mi = 1 hour

because that would make this number of miles is = to 1.2 hours which is wha we're looking for

1.2(10.4) mi = 1.2 hour

2.) Simplify
12.48 mi = 1.2 hour

3.) That means Gina rides 12.48 miles each day if she rides for 1.2 hours each day at a pace of 10.4 miles per hour :)

Answer:

You would plot the following points, remembering that they’re in the form (x,y) = (time, height):

(1,35) (2,60) (3,92) (4,120) (5,175)

The ordered pairs would be closer together, and there would be 4 times more of them if you were to measure every 15 seconds instead. You would have a line with more points that were closer together.
