One number is 5 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 779, find the numbers.

97, 485, 197

Step-by-step explanation:

Given:

Then we have:

Substituting b and c in the third equation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

at least two
