Answer:
The algebraic expression to the model is
Step-by-step explanation:
Consider the provide situation.
You have a summer job at a car wash. you earn $8.50 per hour and are expected to pay a one-time fee of $15 for the uniform.
Let you work for x hours per week and you earn $8.50 per hours, so the money you will earn can be represented as:
8.50 times x or 8.50x
Now you need to pay one time fee of $15 for the uniform.
For the one time fee use a negative sign.
Thus, the required expression is:
The algebraic expression to the model is

Answer:
<h2>19</h2>Step-by-step explanation:
Given the surdic expression , to rationalize the expression, we will have to multiply the numerator and denominator of the expression by the conjugate of the denominator as shown;
Comparing the result with the expression
, it can be seen that A = 6, B = 5, C = -4, D = 11 and E = 1
A+B+C+D+E = 6+5+(-4)+11+1
A+B+C+D+E = 11-4+12
A+B+C+D+E = 19
Hence the value of A+B+C+D+E is 19
