For this case we have the following expression.

$15x + 35y - 40 z$

We must find a term of expression that is repeated in all terms.

We then have the number 5.

By doing common factor 5 in all the expression we have:

$15x + 35y - 40 z = 5 (3x + 7y - 8z)$

Answer:

The factored expression is given by:

$5 (3x + 7y - 8z)$

Answer:

The number is <u>less than</u> 3.5

Step-by-step explanation:

Let us break up and convert each individual phrase into its equivalent in an equation.

"Three time" is $3*$

"The difference of a number and three" is (3-x)

"Is greater than" is >

"The number decreased by five" is (x-5)

We can now put all of these parts together to get our equation

$3*(3-x)>(x-5)$

Now, we can simplify this and solve for x

$3*(3-x)>(x-5)\\\\9-3x>x-5\\\\14>4x\\\\\frac{14}{4} >x\\\\\\frac{7}{2}>x\\\\x$
