Answer:

x + 2

Step-by-step explanation:

Let x be the unknown number,

For making the diagram to model this problem,

Take a grid that shows x, ( shown below )

Then take a grid that shows 2.

Join these grids,

We obtain a grid, showing x + 2

Hence, the required expression that represents the given situation is x + 2

Answer:

a) 4/15

b) 4/15

Step-by-step explanation:

maximum wait is 1 min,2 min,3 min,4 min,5 min,6 min,7 min,8 min,9 min,10 min,11 min,12 min,13 min,14 min,15 min =total 15 values

a) less than 4 min means he has to wait for 1 min, 2 min, 3 min, 4 min=total 4 values

Probability of wait for less than 4 minutes=4/15

b) more than 11 minutes wait means he has to wait for either 12 min, 13 min, 14 min, 15 min=4 values

Probability of wait for more than 11 minutes=4/15

Factor completely. -5 x2y + 10 xy - 15 xy2 I need help.

ASHA 777 [7]

Answer:

$5\,x\,y\,(-x+2-3y)$

Step-by-step explanation:

Always proceed by first extracting all common factors to all terms:

Notice that the factors: 5, x, and y are present in all terms, so we can extract them from the trinomial:

$-5x^2y+10xy-15xy^2\\5\,x\,y\,(-x+2-3y)$

Now, the trinomial left (-x+2-3y) cannot be factored out, so then factoring is complete.

Your answer is 5/6.
1. make the denominators the same as the LCD
1/6+(2*2/3*2)
2. simplify. denominators are now the same
1/6+4/6
3. join the denominators
1+4/6
4. simplify
5/6
