Answer: -5/4


Step-by-step explanation:

Apply the fraction rule: a/-b = -a/b

-5/6/2/3

-----------------------------------------------------------------------------------------------------------------

Divide fractions: a/b/c/d = a x d/ b x c

-5 x 3 / 6 x 2

-----------------------------------------------------------------------------------------------------------------

Multiply the numbers: 6 x 2 = 12

-5 x 3 / 12

-----------------------------------------------------------------------------------------------------------------

Multiply the numbers: 5 x 3 = 15

-15/12

-----------------------------------------------------------------------------------------------------------------

Cancel the common factor.3

-5/4

-----------------------------------------------------------------------------------------------------------------

andre [41]

Using the probability and odds concepts, it is found that the odds against it containing a number greater than or equal to 7 is \frac{2}{3}.

  • A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
  • An odd is the <u>number of desired outcomes divided by the number of non-desired outcomes</u>.

In the rack, there are 15 balls, numbered from 1 to 15. Of those, <u>6 are less than 7</u>(against it containing a number greater than or equal to 7 is equivalent to it containing a number less than 7), thus:

  • There are 6 desired outcomes.
  • There are 9 non-desired outcomes.

The odd is:

\frac{6}{9} = \frac{2}{3}

The odds against it containing a number greater than or equal to 7 is \frac{2}{3}.

4 5/6 Hope this helps.

You have to find the common denominator for 1/3 & 4/8. & it’s 24. By doing that you have to multiply 3x8, when you do that you also have to multiply 1x 8 so you get 8/24 , same with 4/8 but with three so you get 12/24. Then add your answer 20/24, which equals out to 20/24 which reduces to 5/6. Add 5/6 to 2+2 and you’re left with 4 5/6. Hope this helps.

Please help me with this question
romanna [79]

Answer:

E.

Step-by-step explanation:

so first you would add 8 to both sides to get

3w = t + 8

then divide both sides by 3

w = (t + 8) / 3

So the answer is E.

Substitution for:<br> X-5y=10<br> 2x-10y=20
sergey [27]
Since you need an isolated variable to use the substitution method, we need to re-arrange one of the equations. This will probably be easiest to do with the first one.
Add 5y to both sides of the first equation.
x=10+5y
Now, in the second equation, put in 10+5y in any spot that has an x.
2(10+5y)-10y=20
Distribute the 2 to both numbers in the parenthesis.
20+10y-10y=20
Combine like terms.
20=20
This means that the two equations are actually the same. You can see this if you multiply the whole first equation by 2
2(x-5y=10)
2x-10y=20, which is the same as the second equation. Therefore, the two equations are actually the same one.
