10,534,341 is divisible by<br> a. 3<br> b. 9<br> c. 2<br> Explain your reasoning for your choice(s).
Katyanochek1 [597]

Answer:

a. 3

Step-by-step explanation:

We can get to know if a number is divisible by 3 if after adding all the digits of that number we get a number which is completely divisible by 3 or we can say the number appears in the table of 3.

For example: In the given number if we will add all the digits the we will get  21 and we all know that 21 is divisible by 3.

10,534,341 = 1 + 0 + 5 + 3 + 4 + 3 + 4 + 1 = 21

21 = 21/3 = 7

Other options are incorrect.

Divisibility rule for 2 : A number is said to be divisible by 2 if it's ones place ends in 0, 2, 4, 6 or 8 i.e. an even number. The given number does not satisfy this condition because it ends in 1 which is an odd number.

Divisibility rule for 9 : A number is said to be divisible by 9 if after adding all the digits of that number we get a number which is completely divisible by 9. Since the sum total of the given number is 21 which is not completely divisible by 9 we can easily infer that 9 is not the answer for this question.

Answer

Find out  how many  months will it take for Jeff to weigh the same as Darius .

To prove

As given

Jeff and Darius are trying to gain weight for the football team.

Jeff weighs 120 pounds and is gaining  ten pounds per month.

Darius weighs 150 pounds and is gaining 4 pounds per month.

m = represented the number of months will taken by the Jeff to weigh the same as Darius .

Than the equation become in the form

120 + 10m = 150 +4m

150 - 120 = 10m - 4m

30 = 6m

m = \frac{30}{6}

m = 5 months

Therefore in 5 months  will it take for Jeff to weigh the same as Darius.
