10. The ratio of red marbles to purple marbles is 3:8. If there are 44marbles, how many purple marbles are there? *

Answers

Answer:

32 purple marbles.

Step-by-step explanation:

Turn 3:8 into 3x+8x.

Equation:

3x+8x=44

x=4

Now, refer back to 3x:8x. We know that x=4, so 4*8=32.

32 purple marbles.

Answer:

There are 32 purple marbles and 12 red marbles

Step-by-step explanation:

The ratio is 3:8 and the total is 44. For 3 red marbles, they have 8 purple marbles but we don't know how many each marble we need if the total sum is 44. So we do...

3x+8x=44

11x=44

x=4

We need to know the number of purple marbles so we do,

8*4=32

Use the distributive property to rewrite 28*63

Answers

(20+8)*(60+3)
Not sure if this is what you were looking for but I hope it helps.

Final answer:

To use the distributive property to state 28*63, we break down 28 into two smaller numbers say 20 and 8, and then multiply each by 63 and add the products. So, 28*63 is (20*63)+(8*63), which is 1764.

Explanation:

The problem is asking you to use the distributive property to rewrite the multiplication 28*63. The distributive property is about breaking down larger numbers into smaller, manageable parts. Now, this involves a strategy of breaking down the numbers.

Let's break down the number 28 into 20 and 8.  So, the multiplication could be rewritten as (20 + 8) * 63.

Now apply the distributive property (also known as Distributive Law of Multiplication) which states that multiplying a number by a sum of two numbers is equivalent to multiplying the number individually by each of the numbers and then adding the products together.

So,  (20 + 8) * 63 equals (20*63) + (8*63)

The final answer to the equation would be (20*63) + (8*63) = 1260 + 504 = 1764.

Candice is traveling to Paris, where they measure distance in Kilometers and not miles . The taxi driver tells her that the distance from the airport to the hotel is 3,000 meters . How many kilometers is this ?

Answers

Therefore , the solution of the given problem of unitary comes out to be  3 kilometres from the airport to the motel.

What is an unitary method?

By combining the information obtained using this variable technique with all supplementary data from two individuals who used a specific tactic, the job can be completed. This mean that, if indeed the desired outcome materialises, either the stated person will be recognized or, in actuality, the colour by both huge processes will be skipped. For forty pens, a refundable charge of Rupees ($1.01) might be required.

Here,

Since there are 1,000 metres in a kilometre, we must split by 1,000 to convert metres to kilometres.

Thus, we can split by

=> 1,000 to convert 3,000 metres to kilometres:

=> 3 kilometres =  3,000 metres / 1,000.

Consequently, it is 3 kilometres from the airport to the motel.
