Answer:

5/36

Step-by-step explanation:

To carry out this subtraction of fractions we need to obtain and use the LCD (lowest common denominator). This LCD is the smallest new denominator evenly divisible by both 12 and 9. In this case the LCD is found by multiplying 12 and 9 together, obtaining 108.

Then 11/12 = 99/108 and 7/9 = 84/108, and

11/2 - 7/9 becomes the equivalent 99/108 - 84/108, or 15/108.

This fraction should be reduced as much as possible. Note that both 36 and 108 are evenly divisible by 12, so 15/108 = 5/36. This is the answer you want.

Log (w2+21) - log (10)

UNO [17]

Answer:

$w =7\ or\ w =3$

Step-by-step explanation:

Given

The right question is:

$\log(w^2+ 21) = \log(10w)$

Required

Solve for w

$\log(w^2+ 21) = \log(10w)$

Cancel log on both sides

$w^2+ 21 = 10w$

Equate to 0

$w^2 - 10w+ 21 = 0$

Split

$w^2 - 3w - 7w+ 21 = 0$

Factorize

$w(w - 3) - 7(w-3) = 0$

Factor out w - 3

$(w - 7)(w-3) = 0$

Solve for w

$w - 7 = 0\ and\ w - 3 = 0$

$w =7\ or\ w =3$

Solve for x: 12 (x – 4)| + 7 = 25.

Rasek [7]

Question:

Solve for x: $12|x-4|+7=25$ . Fill in both values for x below. Write the greater value for x in the first column.

Answer:

$x=5.5$ and $x=2.5$ are the values for x.

Explanation:

The equation is $12|x-4|+7=25$

Subtracting both sides by 7,

$12|x-4|=18$

Dividing both sides by 12,

$|x-4|=1.5$

Now, we shall write the equation by removing modulus by adding plus and minus on the other side of the equation.

$x-4=1.5$ or $x-4=-1.5$

Solving the equation $x-4=1.5$ , we get,

$\begin{aligned} x-4 &=1.5 \\ x &=1.5+4 \\ x &=5.5 \end{aligned}$ or $\begin{aligned} x-4 &=-1.5 \\ x &=-1.5+4 \\ x &=2.5 \end{aligned}$

Thus, the solutions are $x=5.5$ and $x=2.5$
