Solving algebraic equations:

5n+1

What do I do to solve this?

Explanation:

The given expression is not an equation. There is nothing that can be solved.

___

An equation has an equal sign between its left side and its right side. Solving it means finding a value for the variable (or variables) such that the equation is true.

For example, we might have ...

  5n +1 = 1

Your familiarity with math facts means you know that ...

  0 +1 = 1

In order for the term 5n to have a value of 0, the value of n must be 0 in this equation. The solution to 5n+1 = 1 is n = 0, because 5×0 + 1 = 1 is a true statement.

___

An expression can be evaluated. To do that, put the value you want the variable to be every place you see the variable, then do the arithmetic.

To evaluate 5n+1 for n=6 we put 6 in place of n:

  5×6 +1

Doing the arithmetic, we get ...

  = 30 +1 = 31

The value of 5n+1 for n=6 is 31.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
