15(2-x)=13(3-x) pls help
schepotkina [342]

Answer:

-4.5

Step-by-step explanation:

15(2-x)=13(3-x)

Expand parentheses:

30-15x=39-13x

Add 15x to both sides:

30=2x+39

Subtract 39 from both sides:

2x=-9

Divide both sides by 2:

x=-4.5

Hope this helps!

kirill115 [55]

Answer:

There are 12 sets of four marbles include all the red ones.    

Step-by-step explanation:

Given : A bag contains three red marbles, two green ones, one lavender one, four yellows, and five orange marbles.

To find : How many sets of four marbles include all the red ones?

Solution :

Number of red marbles = 3

Number of green marbles = 2

Number of lavender marbles = 1

Number of yellow marbles = 4

Number of orange marbles = 5

We have to form sets of four marbles include all the red ones,

For position of getting red ones we have three red marbles i.e. ^3C_3

For the fourth one we have 12 choices i.e. ^{12}C_1

Total sets of four marbles include all the red ones is

=^3C_3\times ^{12}C_1

=1\times 12

=12

Therefore, There are 12 sets of four marbles include all the red ones.
