Answer:
a) After 10 weeks Jim and Rhonda will have the same amount.
b) They both would have $350 in their account after 10 weeks.
Step-by-step explanation:
Given:
Amount Jim has = $310
Amount Jim adds per week = $4
Let the number of weeks be 'x'.
So we can say that;
Total amount Jim will have after 'x' week will be equal to amount Jim has plus amount Jim adds per week multiplied by number of weeks.
framing in equation form we get;
Total amount Jim will have after 'x' week =
Also Given:
Amount Rhonda has = $260
Amount Rhonda adds per week = $9
So we can say that;
Total amount Rhonda will have after 'x' week will be equal to amount Rhonda has plus amount Rhonda adds per week multiplied by number of weeks.
framing in equation form we get;
Total amount Rhonda will have after 'x' week =
a) We need to find the number of weeks in which the both will have same amount;
Now to find number of weeks in which the both bill have same amount;
we have to make both the equation equal and solve the same we get;
Combining the like terms we get;
Now using Division property of equality we will divide both side by 5 we get;
Hence After 10 weeks Jim and Rhonda will have the same amount.
b) We have to find amount they would have after 10 weeks.
To find the same we will substitute value of 10 in each equation we get;
Total amount Jim will have after '10' weeks =
Total amount Rhonda will have after '10' weeks =
Hence They both would have $350 in their account after 10 weeks.

Step-by-step explanation:
An algebraic expression is a polynomial if and only if the variables involve have positive integral indices or exponents.
The given polynomial is:
We want to put one of the following polynomials in the blank space to create a fully simplified polynomial written in standard form.
A fully simplified polynomial written in standard form is obtained by writing the simplified polynomial in decreasing order according to degree.
Since the first term of having a degree of 5 and the last term is having a degree of 3.
The polynomial that goes into the blank must have a degree of 4.
This eliminates ,
and
We are now left with and
The required polynomial is therefore or
These two polynomials are in standard form and cannot be simplified further.
The correct choices are;
and
