Answer: Ashley has $20

Chau has $15

Rueben has $40

Step-by-step explanation:

Let x represent the amount that Ashley has.

Let y represent the amount that Chau has.

Let z represent the amount that Rueben has.

Ashley,chau, and reuben have a total of $ 75 in their wallets. This means that

x + y + z = 75- - - - - - - - -- - -1

Chau has $5 less than ashley. This means that

y = x - 5

Reuben has  2 times what ashley has. This means that

z = 2x

Substituting y = x - 5 and z = 2x into equation 1, it becomes

x + x - 5 + 2x = 75

4x = 75 + 5 = 80

x = 80/4 = 20

y = x - 5 = 20 - 5

y = 15

z = 2x = 2 × 20

z = 40

What two partial products would you add to find 513 x 46
Afina-wow [57]
First, let me do the Mathematical part of that, and then I shall explain the theory behind it.

Mathematical part:
We are going to multiply 513 with 46. So the two partial products that we are going to choose are 40 and 6.

Multiply 513 with 6 first.

    513
    x46
--------------------------
      18 (as 6*3 = 18)
      60 (as 6*10 = 60; In 513, the digit at tenths place is 1, so 1*10=10)
  3000 (as 6*500 = 3000; In 513, 5 is at hundredth place, so 5*100=500)
    120 (as 40*3 = 120; since 4 is at the tenth place, so 4*10=40)
    400 (as 40*10 = 400)
20000 (as 40*500 = 20000)
--------------------------
23598 (Add all of them)


Theory:
As you can see above that we have chosen the two partial products individually which are 6 and 40. Since 4 in 46 is in tenth place, we have to consider it 40 (since 4*10 = 40). One by one, we first multiply 6 with 513. Then we move to the tenth place, and multiply 513 with 40. At the end, we have added all the results we found after multiplication.

Check: If we check the multiplication result by using the calculator, we would get the same result (23598).

Another Method (instant):
513 * (40+6) = (513*40) + (513*6) = 23598.
