Now lets see how much she earns in 15 hrs.

19.32 × 15 = 289.8
Tiffany earns $289.8 to work for 15 hrs.

289.8 ÷ 15 = 19.32
we were RIGHT!!

So, Tiffany earns $289.8 to work for 15 hrs.

Hope I helped ya!! 
Divide 77.28 by 4. Multiply the answer by 15. =(15)(19.32)=289.8

Will the sum of two linear expressions each with an x-term , always,sometimes,or never have an x-term ? Explain your reasoning

Answers


The sum will have an x-term sumtimes ... whenever
the x-terms alone don't add up to zero.

Examples:

-- Two linear expressions:

         y +  x
and   
         y + 2x

The sum of the x-terms alone is (x + 2x) = 3x .
So the sum of the expressions has an x-term.

         (y + x) + (y + 2x)  =  2y + 3x .
_______________________________

Two different linear expressions:

       y + 3x
and
       y - 3x

The sum of the x-terms alone is (3x - 3x) = zero.
So the sum of the expressions doesn't have an x-term.

         (y + 3x) + (y - 3x)  =  2y .
