1 inch = 4 ft

so 7.5 inches = (7.5 * 4) = 30 ft
and 12 inches = (12 * 4) = 48 ft

A = L * W
A = 30 * 48
A = 1440 square ft <=

Set up a linear system and solve. The sum of two positive integers is 17. When the smaller integer is subtracted from five times
solniwko [45]

The numbers are 7 and 10 if the sum of two positive integers is 17 and the smaller integer is subtracted from five times the larger, the result is 43.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Set up a linear system and solve. The sum of two positive integers is 17.

When the smaller integer is subtracted from five times the larger, the result is 43.

Let the numbers x and y:

x + y = 17

5y - x = 43  ( let x < y)

Solving the above two linear equations in two variables:

x = 17 - y

5y - (17 - y) = 43

5y - 17 + y = 43

6y = 60

y = 10

x = 17 - 10 = 7

Thus, the numbers are 7 and 10 if the sum of two positive integers is 17 and the smaller integer is subtracted from five times the larger, the result is 43.
