One number is 4 less than a second number. twice the second number is 47 more than 5 times the first. find the two numbers.

Let the two numbers be x and y, respectively the first and second. We can translate the sentences into equations:

One number is 4 less than a second number:

Twice the second number is 47 more than 5 times the first:

Which leads to the following linear system:

The first expression gives a way to express x in terms of y. Use this expression to substitute x in the second equation:

Use the first equation to deduce the value of x, now that we know the value of y:

use google you idiot omg you're so annoying

step-by-step explanation:

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
