Answer:

  • 1
  • 40
  • 36

Step-by-step explanation:

You know that 9 = 10 - 1.

Then 9 of something is equal to 10 of it less one of it. Here, that "something" is four.

  \begin{array}{cl}9\times4&=10\text{ fours}-\boxed{1}\text{ four}\\&=\boxed{40}-4\\&=\boxed{36}\end{array}

_____

<em>Comment on this math</em>

This illustrates a shortcut for multiplying by 9 that can be convenient for mental arithmetic. The idea is to multiply by 10, which just involves adding 0 (or moving the decimal point), then subtract the original number.

Sonja [21]

Answer: the correct answer is c.$81

Step-by-step explanation:

When there are multiple markets for an asset, the fair value of an asset is determined based on prices in the principal or most advantageous market. The second market is more advantageous because it has the higher selling price ($80 is greater than $76). In addition, fair value includes transaction cost; therefore, the valuation of the asset would be $81 = $80 + $1.

How do i do this? Explain the answer and how it is done.
zzz [600]

Answer:

4/9ths of a cup of sugar is needed for one cup of flour.

Step-by-step explanation:

To answer this you need to scale the number of cups of flour up from 3/4 to 1  that ratio would be 4/3 (multiplying a fraction by its own reciprocal will give you 1).

We can then simply take that ratio, and scale the sugar by the same amount:

1/3 * 4/3 = 4/9

Three consecutive integers have a sum of 15. What are the integers?<br>​
Mice21 [21]

Answer:

4, 5, 6

Step-by-step explanation:

First integer is X, consecutive is (x+1), next consecutive is (X+1+1)=(X+2)

Three consecutive integers have a sum of 15. X+X+1+X+2 = 15

X+X+1+X+2 = 15

3X + 3 = 15

3X = 15-3

3X = 12

X = 4

X+1 = 4+1=5

X+2 = 4+2=6

Check: 4+5+6=15, 15=15

Flauer [41]
Bea has $550 more money than Alessandro after 12 months.
Explanation:
So let start with writing the equation for Alessandro money. So we know that the current amount in his/her bank account has $2,400 and she saves $250 per month. So the equation that best fit these terms is:
