(t-8)-(t+15) find the difference

Let's simplify step-by-step.

t−8−(t+15)

Distribute the Negative Sign:

=t−8+−1(t+15)

=t+−8+−1t+(−1)(15)

=t+−8+−t+−15

Combine Like Terms:

=t+−8+−t+−15

=(t+−t)+(−8+−15)

=−23

=−23

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
