Example Questions

Example Question #521 : Algebra

Possible Answers:

Correct answer:

Explanation:

First, simplify the equation by subtracting 27 from 22. Since 27 is greater than 22 the resulting difference will be negative:

Then isolate the variable by multiplying each side of the equation by -6. 

Recall that when two negatives are multiplied together their product becomes positive.

Example Question #522 : Algebra

Possible Answers:

Correct answer:

Explanation:

First, isolate the variable.

This is done by multiplying both sides of the equation by the reciprocal of  which is .

 

Note: If you wanted to simplify the fraction , that would have made it easier to do this problem.

However, the answer is still,

.

 

 

Example Question #523 : Algebra

A piece of wood is cut into 14 equal pieces.  The wood was originally 196 cm long. What algebraic equation would you use to solve this, and what would the answer be?

Possible Answers:

Correct answer:

Explanation:

To write this statement as an algebraic equation we need to pick out some identifiers.

A piece of wood is cut into 14 equal pieces.  This means that each piece of wood is the same length or in mathematical terms: 14x

The wood was originally 196 cm long, in mathematical terms 196=

The equation will be in the form of,

Therefore the equation becomes,

.

To solve, divide each side by 14.

Example Question #524 : Algebra

Possible Answers:

Correct answer:

Explanation:

To solve this function first simplify the right hand side of the equation by adding the two terms together.

From here isolate the variable by multiplying both sides by 0.15.
