Answer:

Part 1 = 15

Part 2 = 25

Part 3 = 30

Step-by-step explanation:

Ratio = 3 : 5 : 6

Sum of the ratio terms = 3 + 5 + 6 = 14

Then,

$\cdot \:\: \frac{3 * 70}{14} =15\\ \\\cdot \:\: \frac{5 * 70}{14} =25\\ \\\cdot \:\: \frac{6 * 70}{14} =30$

Answer:

All are correct

Step-by-step explanation:

If Friend A gives 145 and Friend C gives 245 they already have a total of $390 out of the $700. So the missing amount is 310, half that for both friends and get 155, so the last 2 could both pay 155. No matter which way you put the number you will get the same answer. And as the communitive property states "The numbers on which we operate can be moved or swapped from their position without making any difference to the answer." and all of the answer choices apply to that statment.

Answer:

The weight of large box = 13.75 kilograms

the weight of small box = 6.5 kilograms

Step-by-step explanation:

Given:

delivery of 2 large boxes and 3 small boxes has a total weight of 47 kilograms

delivery of 6 large boxes and 5 small boxes has a total weight of 115 kilograms.

Let x be the weight of large box

and y be the weight of small box

Make equation from the given information

2(weight of large box) + 3(weight of small box) = 47

2x + 3y = 47 -----------> equation 1

Do the same and make one more equation

6x + 5y = 115-----------> equation 2

Now we solve both equation using elimination method

Multiply the first equation by 3

6x + 9y = 141

6x + 5y = 115 (subtract both equations)

----------------------------------------------------

4y = 26

divide both sides by 4

So y= 6.5

Now plug in 6.5 for y and find out x

2x+3y = 47

2x + 3(6.5) = 47

2x + 19.5 = 47 (subtract 19.5 on both sides)

2x = 27.5

divide both sides by 2

x = 13.75

The weight of large box = 13.75 kilograms

the weight of small box = 6.5 kilograms
