If it takes Maddox 7.5 hours to drive 375 miles, how far could he drive in 3 hours at the same rate?

Answers

Answer 1

Answer:

Answer:

150 miles

Step-by-step explanation:

We can use ratios to solve

375 miles x miles

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

7.5 hours 3 hours

Using cross products

375 * 3 = 7.5 x

1125 = 7.5x

Divide each side by 7.5

1125/7.5 =x

150 x

Answer 2

Answer:

Answer:

150 miles

Step-by-step explanation:

375 divided by 7.5 is 50

50 time 3 is 150

9474

Check the number to the right:

9474

If the number is greater than or equal to 5, we round up. If the number is less than or equal to 4, we round down.

Since there is a '4', we round down.

9474 ≈ 9000

From c to the midpoint the coordinates have changed from (-1;9) to (-9;-10). So the difference is (-9-(-1); -10-(9)) that equals (-8;-19). And you should add (-8;-19) to the coordinates of the middle point (-9;-10). So we get (-9+(-8); -10+(-19)) that is (-17;-29). This is the endpoint of d. Answer: d (-17;-29).

Which equation represent slope-intercept form of line

Answers

Well for it to be slope intercept form you would look for the equation;
Y=mx+b. So just look for an equation that has y= a number then x then + another number. An example of slope intercept would be y=1/2x+3. Good luck!
