Atwo digit number is 4 times the sum of its digits .it is equal to 3 times the product of digits .find the numb

The number is 24

Step-by-step explanation:

Let x and y be the 2 digits .

Note that because x and y are integers and the original number is a multiple of 3 and 4, it must also be a multiple of 12.

So by trial and error:-

Let the number be 12:-

x + y = 3 and 4 * 3 = 12  so this fits the first condition.

x * y = 2  and 3 * 2 = 6 . This does not fit.

Let the number be 24:-

xy =24 , x + y = 6 and 4*6 = 24 . This fits.

x*y = 8 and x*y = 24 This fits.

The answer is 24

the probability that a bird is green (.30) is true

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
