Answer:

1.5

Step-by-step explanation:

First put like terms on one side:

-3/8d - 1/2d = -11/16 - 5/8

then make the demominators the same:

-3/8d - 4/8d = -11/16 - 10/16

add up the terms:

-7/8d = -21/16

solve for d:

d= 1.5

P what equation in slope-intercept form represents the line that passes through the points (3,5) and (-9,2)

ivanzaharov [21]

Answer:

$y =\frac{1}{5}x+\frac{22}{5}$

Step-by-step explanation:

To write the equation of a line, use the slope formula to first find the slope.

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{5-2}{3--9}=\frac{3}{3+12}=\frac{3}{15}=\frac{1}{5}$

Substitute m=1/5 and the point (3,5) into point slope formula.

$y-y_1 = m(x-x_1)\\y-5=\frac{1}{5}(x-3)\\y-5=\frac{1}{5}x -\frac{3}{5}\\y =\frac{1}{5}x+\frac{22}{5}$

Charlie runs laps around a track. The table shows how long it takes him to run different numbers of laps. How long would it take

geniusboy [140]

There are a couple ways to determine the number of minutes it will take Charlie to run 9 laps, but the easist would be to find out what is happening to each number of laps in order to get the number of minutes. In each case, the number of laps is being multiplied by 5 to get the number of minutes.
9x5=45 minutes.

He is running each lap in 5 minutes.
