Answer:

x>3

Step-by-step explanation:

24 - 12x < 6x - 30

1. Get x on one side of the equal sign. Do this by adding 12x to both sides of the equal sign.

24 - 12x < 6x - 30

+12x +12x

24 < 18x - 30

2. Get x by itself. Do this by adding 30 to both sides of the equal sign.

24 < 18x - 30

+30 +30

54 < 18x

3. Divide 18 to both sides of the sign

3 < x

Answer:

x > 3

Step-by-step explanation:

Given

24 - 12x < 6x - 30 ( subtract 6x from both sides )

24 - 18x < - 30 ( subtract 24 from both sides )

- 18x < - 54

Divide both sides by - 18, reversing the symbol as a result of dividing by a negative quantity.

x > 3

How many eighty fours are in 672

Zinaida [17]

Answer

Find out how many eighty fours are in 672.

To prove

Let us assume that the number of the 84 be x .

As given in the equation

Total values given in the question be 672.

Than the equation becomes

84 × x = 672

Simplify the above equation

84x = 672

$x = \frac{672}{84}$

x = 8

Therefore the Numbers of eighty fours in 672 is 8 .

Simplify completely quantity 4 x squared minus 32 x plus 48 all over quantity 3 x squared minus 17 x minus 6.

Yuki888 [10]

For this case we must simplify the following expression:

$\frac {4x ^ 2-32x + 48} {3x ^ 2-17x-6}$

Simplifying the numerator, dividing all the terms by 4, we have:

$x ^ 2-8x + 12$

We factor by looking for two numbers that when added together give -8 and when multiplied by 12. These are: -6 and -2

$-6-2 = -8\\-6 * -2 = 12$

So, we have to:

$x ^ 2-8x + 12 = (x-6) (x-2)$

Simplifying the denominator:

We rewrite -17x as -18x + x:

$3x ^ 2-18x + x-6$

We factor the highest common denominator of each group:

$3x (x-6) +1 (x-6)$

We factor the polynomial by factoring the highest common denominator (x-6):

$(x-6) (3x + 1)$

So, we have to:

$3x ^ 2-17x-6 = (x-6) (3x + 1)$

Substituting in the original expression we have:

$\frac {(x-6) (x-2)} {(x-6) (3x + 1)} = \frac {x-2} {3x + 1}$

ANswer:

$\frac {4x ^ 2-32x + 48} {3x ^ 2-17x-6} = \frac {x-2} {3x + 1}$

The two shorter sides of a triangle are the same length. the length of the longer side is 5 m longer than each of the shorter si

ziro4ka [17]

P=a+b+c. Sub in what we know: 29=a+a+(a+5). Combine like terms: 29=3a+5. Subtract 5 from both sides: 24=3a. Divide by 3: 8=a. Short sides: A=8m, b=8m, long side: c=13m. :)

Sergio [31]

The first step for solving this is to cancel equal terms on both sides of the inequality.
$- \frac{x}{2}$ < 0
Now multiply both sides of the inequality by -2 and flip the inequality sign.
-2 × ( $- \frac{x}{2}$ ) > -2 × 0
Remember that multiplying two negatives together always equals a positive,, so the expression changes to the following:
2 × $\frac{x}{2}$ > -2 × 0
Reduce the numbers with 2.
x > -2 × 0
Any expression multiplied by 0 equals 0,, so the correct answer to your question will be:
x > 0
Let me know if you have any further questions.
