Abag contains white marbles and yellow marbles, 16 in total. the number of white marbles is 5 less than 2 times the number of yellow marbles. how many white marbles are there?

9 White marbles are present in the bag.

Step-by-step explanation:

Let the number of White marbles present in the bag be X and number of Yellow marbles present be Y .

Then according to the question ,

X + Y = 16      -(1)        (As total marbles are 16)

Also,

X = 2Y - 5      -(2)

From Equation 1 , X = 16 - Y  , Comparing with Equation 2 , we get,

16 - Y = 2Y - 5

3Y = 21.

Y = 7.

So, X = 16 - Y = 16 - 7 = 9.

Thus, 9 White marbles are present in the bag.

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
