by how much is the product of 51 and 42.65 smaller than 3000 ? please give answer in steps​

Answer 1

Answer:

hope i helped you

Step-by-step explanation:

Let n = the smaller number, and since the other number is twice the smaller one, then ...

Let 2n = the larger number.

Since "the sum of the two numbers is 51," then we can translate this statement mathematically into the following equation to be solved for n as follows:

n + 2n = 51

Collecting like-terms on the left-hand side of the equation, we get:

3n = 51

Now, divide both sides by 3 in order to isolate and thus solve for the unknown quantity n as follows:

(3n)/3 = 51/3

(3/3)n = 51/3

(1)n = 17

n = 17

Therefore, ...

2n = 2(17)

= 34

CHECK:

n + 2n = 51

17 + 34 = 51

51 = 51

Therefore, the two desired numbers are indeed 17 and 34.

Answer 2

Answer:

Divide both sides by 3 and we see that x=51/3 =17 ... The sum of two numbers is 22, the larger number is two less than twice the ... Let the two numbers be x and y and y is twice of x.
