Me with the fraction problems . it's linear inequalities.

i need with 3, 7, 8, and 12

3.

Multiply both sides by 4:

Subtract and 1 from both sides:

7.

Multiply both sides by 6; this choice is motivated by the fact that and . In other words, 6 is the least common multiple of 3 and 2, which allows us to eliminate the denominators of the fractions in this inequality.

Subtract and 18 from both sides:

8. Since these are all linear inequalities, I think this is supposed to read

Multiply both sides by 2:

Subtract and -2 from both sides:

Divide both sides by 5:

12.

12 is the least common multiple of 4 and 3; distributing it to both terms on the left gives

so we have

Subtract 3 from both sides:

Divide both sides by 4:

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
