A student on the cross-country team runs 30 minutes a day as a part of her training.
Write an equation to describe the relationship between
the distance she runs in miles, D, and her running
speed, in miles per hour, when she runs at a constant
speed of 4 miles per hour for the entire 30 minutes.

step-by-step explanation:

10.50 + taxes which added up to 11.50

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.

y= -2x+4, have a great day
