Homework Help: pre-algebra

Posted by Billy on Wednesday, March 7, 2007 at 10:48pm.

Solve an equation-

4r-6+2r=6

Write an equation and solve it-

Thirty-six sections of fencing,all the same length,are joined to form a fence 180m long. How long is each section of fencing?

Write an inequality for the sentence.
The total t is greater than five.

Get all the letter terms on one side and the numerical ones on the other, then combine.

4r + 2r- 6 + 6 = 6 + 6

You can do the rest.

Let X stand for the length of each section. In the formula, indicate how many sections of fence are needed to complete the whole fence. Think it out.

">" means "greater than" and "<" means "less than." Substitute the symbols and numbers into the sentence for your inequality.

I hope this helps. Thanks for asking.
