\(\dfrac 6 {42} = \dfrac 1 7\)

HEY! That is rude and offensive to the person asking the question! How could you, you t**t!?

\(0.5 x \ln(x) -1.5 x = 0 \\ 0.5 x \ln(x) = 1.5 x \\ x \ln(x) = 3 x \\ \mbox{Since }\ln(0) \mbox{ is not defined }x \neq 0 \mbox{ and we can divide both sides by }x \\ \ln(x) = 3 \\ x = e^3\)

6k-9=15    add 15 to both sides

6k = 24     divide both sides by 6

k = 4

Take a left.

No big deal, Omi.....it was just a slight mistake......we all make them  !!!!!!

CPhill: If you are competent in complex math, this young person wants to know the steps involved.

A SaskTel phone card regularly priced at $20.00 is on sale for $15.00. A Rogers phone card valued at $10.00 is on sale for $7.00. Which of these offers are the greatest discount?

Find the discount rate for both and then compare:

15/20=.75, so the dicount is 1 - .75=.25 X 100=25%

7/10=.70, so the discount is 1 - .70=.30 X100=30%

So, Rogers phone card is a better deal.

3x5=15

2^3=2*2*2=8

I hate math.

This is TRUE statement or equation.

Correction: I'm so sorry

Solve for x:
(2 (6 x-9))/3 = 2 x+4

Multiply both sides by 3:
(3×2 (6 x-9))/3 = 3 (2 x+4)

(3×2 (6 x-9))/3 = 3/3×2 (6 x-9) = 2 (6 x-9):
Answer: | 
| 2 (6 x-9) = 3 (2 x+4)

x=5

2/3(6x-9)=(2x+4)    simplify the left side

4x - 6  = 2x + 4      add 6 to both sides, subtract 2x from both sides

2x = 10      divide both sides by 2

x = 5

4/6=2/3, I divided both sides by 2.

The object swims because its density is lower.

4/6 simplified is 2/3/

4/6 as a percent is 67%

4/6 as a decimal is 0.6666...

You have probably seen this famous equation: E=mc^2, which means: Energy=Mass X Speed of Light squared.

cot = cos / sin =  [ sqrt(15 ) / 4 ] / [1 / 4]  = [  sqrt(15)/ 4 ] * [ 4 / 1 ]  =   sqrt(15)

This is the exact value.

since 13g/21cc simplifies to 0.619 g/cc, it has less density than the Isopropyl alcohol, and thus will float.

How many pound is 0.11 metric tonnes?

The correct answer is:242 pounds and 8 ounces, since 1 metric tonne=2,205 pounds.

Jonas gets an orange, 5/11 chance. Since Jonas took a fruit from the basket, subtract 1 from the number of oranges as well as from the total number of fruit. Beth gets an apple, 4/10 chance.

Multiply the two probabilities together.

5/11 * 4/10 = 20/110 = 2/11
