The length of the boston marathon is 138,435 ft. each stride, or step, by a particular runner is 3 ft long. does the number of strides the runner takes fit evenly into the length of the race? explain

Fit evenly basically means does the runner need to take a whole number of steps to complete the race, assuming the runner travels a consistient distance per stride

easy way is
is 138435 divisble by 3?
a hack to tell if a number is divisble by 3 is to add the digits and if the sum is divisble by 3, it is divisble
1+3+8+4+3+5=24
24 is 3 times 8

it is divisible by 3
yes

Yes! If you divide 138,435 by 3, the number of strides the runner takes fit evenly into the length of the race. Therefore the answer is 46,145 ft.

y = 1/2x - 4

Step-by-step explanation:

The x-intercept is when y = 0, so it would be:

-x  + 2 * 0 = 4

-x = 4

x = -4

That means the x-intercept is (0, -4)

The parallel line would have the same slope as this one, so:

The parallel line has a slope of 1/2

So now you need to find the equation of a line that has a slope of 1/2 and passes through the point (0, -4)

Put it in point slope form:

y - (-4) = 1/2(x - 0)

y + 4 = 1/2x

y = 1/2x - 4
