We can calculate the mmc between 8 and 12

8, 12 | 2

4 , 6 | 2

2 , 3 | 2

1 , 3 | 3

1, 1 | 1

mmc = 2 × 2× 2×3

mmc = 24

24 ÷ 8 = 3

And

24 ÷ 12 = 2

3/8 + 5/12 = ( 3× 3+ 5×2)/24

= (9 + 10)/24

= 19 / 24

Answer = 19/24

Another way of calculating would be to multiply the denominator and multiply the extremes.


3/8 + 5/12 = ( 3 × 12 + 8×5)/8×12

= ( 36 + 40)/96

= 76/96

Division by 2

= 38 / 48

Division by 2

= 19 / 24

I hope this has helped.

the temperature at noon was -27 degrees . the temperature increased by 13 degrees by 2pm . what was the temperature at 2pm
Aleks [24]
First, you would create an equation for this problem. 
-27 + 13

Now, all you would have to do is solve it. 
-27 + 13 = -14

By 2 pm the temperature was -14 degrees. 

I hope this helps!

If a x 10^n is scientific notation, then a must be between 1 and
Yanka [14]

Answer:

  A)  10

Step-by-step explanation:

In the US, a number in scientific notation will have a mantissa (a) such that ...

  1 ≤ a < 10

That is, the value of "a" must be between 1 and 10 (not including 10).

_____

<em>Comment on alternatives</em>

In other places or in particular applications (some computer programming languages), the standard form of the number may be a×10^n with ...

  0.1 ≤ a < 1

In engineering use, the form of the number is often chosen so that "n" is a multiple of 3, and "a" is in the range ...

  1 ≤ a < 1000

This makes it easier to identify and use the appropriate standard SI prefix: nano-, micro-, milli-, kilo-, mega-, giga-, and so on.

If f ( x ) = 3 - i and g ( x ) = 4i,
klemol [59]

Answer:

f(x)g(x) = (3 - i)(4i) \\  = 12i - 4 {i}^{2}  \\  =  \boxed{12i  + 4 }\\ remember \:the \: value \: of \:  {i}\: is \:  \sqrt{ - 1}  \\ and  \: {i}^{2}  \: is - 1 \\ d. (4 + 12i)\: is \: the \: right \: answer.

How many solutions can be found in the linear equation? 3(x+4)=3x+4
Daniel [21]
3(x + 4) = 3x + 4
3x + 12 = 3x + 4
3x - 3x = 4 - 12
0 = -8 (incorrect....no solution)

little tip ...
if it ends with a variable equaling a number, like x = 2 or y = 4, then there is 1 solution.
if it ends with something unequal with no variable, like 0 = -4 or 5 = 7, then there is no solution.
if it ends with something equaling with no variable, like 2 = 2 or 5 = 5, then there is infinite solutions.
