Answer:

-4/6, -6/9, -8/12

Step-by-step explanation:

All you're doing is multiplying each side, like for -4/6, you multiply -2 by 2 and multiply 3 by 2 to get -4/6. Remember whatever you do to one side you must do to the other

Solve: 3(2x+7) S 6(x-4)

Alenkasestr [34]

Answer:

no solution

Step-by-step explanation:

3(2x + 7) ≤ 6(x - 4) ← divide both sides by 3

2x + 7 ≤ 2(x - 4)

2x + 7 ≤ 2x - 8 ( subtract 2x from both sides )

7 ≤ - 8 ← False statement

This means the inequality has no solution

Which number produces an irrational number when multiplied by 0.4

vovikov84 [41]

Assuming 0.4 is in fact, 2 divided by 5 (and not an approximation of some number that would require an infinite amount of decimal places to exactly express), then multiplication by 0.4 is the same as multiplying by 2 and dividing by 5.

This means that multiplying any rational number by 2/5 will yield another rational number (as given x/y as an input, where x and y are integers, and multiplying it by 2/5 giving 2x/5y, will mean that 2x and 5y are also integers, and the result is also rational)

If we multiply an irrational number by 2/5, however, the result will be irrational.

So your answer is any number not in the set of rational numbers, multiplied by 0.4, will yield an irrational number.
