The solution to x - 8 > - 3

Answers

Answer: x > 5

Step-by-step explanation: To solve for x in this inequality, your goal is the same as it would be if you were solving an equation, to get x by itself on one side.

Since 8 is being subtracted from x, add

8 to both sides of the inequality.

On the left the -8 +8 cancels out

and on the right, -3 + 8 is 5.

So we have x > 5.

Debbie cut a cord into sixths . She used five of the to make necklaces . She used equal lengths of the remaining cord for each of four bracelets. What fraction of the original cord did Debbie use for each bracelet ?

Answers

So she used (5)/(6) of the cord to make necklaces.
1- (5)/(6) = (1)/(6)

She splits the (1)/(6) length into 4 equal lengths.
To divide a fraction by a fraction, you multiply it by its reciprocal.
(1)/(6) ( (1)/(4))
=(1)/(24)

She used (1)/(24) of the original chord to make each bracelet.
