Hi there! I can help you! So on the map, Stafford and Princeton is 6 1/4 miles apart. To find the distance from Stafford to Georgetown, add the numbers 3 1/2 and 3 3/4, in order to get 7 1/4. This is because you have to also add the distance from Stafford to Arlington and THEN add the distance from Arlington to Georgetown. Now, let’s subtract the numbers. 7 1/4 - 6 1/4 is 1. There. It is 1 mile farther from Stafford to Georgetown, than from Stafford to Princeton.

Please help!! You want to distribute 7 candies to 4 kids. If every kid must receive at least one candy, in how many ways can you

Andrei [34K]

Answer: 20ways

Step-by-step explanation:

Number of candies = 7

Number of kids = 4

Since each kid must receive at least one candy ;

Therefore number of candies left to ration is

7 - 4 = 3 candies ; among 4 kids.

To share 'n' identical object among 'r' number of individuals can be expressed in the form :

[n+(r-1)Cr-1]

n = 3 ; r = 4

[3+(4-1)C4-1] = 6C3

Recall: nCr = n! / (n-r)!r!

6C3 = 6!/(6-3)!3!

6C3 = 6!/3!3!

= (6 * 5 * 4) / (3 * 2 * 1)

= 120 / 6

= 20ways

Solve the simultaneous equations 4x+8y=-4 2y-5x=23

ad-work [718]

Answer:

x = -4, y = 3/2

Step-by-step explanation:

simplify the 1st equation by dividing each term by 4 to get:

x + 2y = -1

-5x + 2y = 23

Subtract to get: 6x = -24

x = -4

find 'y': 2y - 5(-4) = 23

2y + 20 = 23

2y = 3

y = 3/2

When asked to find a number one-tenth as large as another number, what operation would you use? What about when asked to find a

kherson [118]

Apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.

<u>Solution:</u>

Need to determine what operation is required to get one-tenth of a number and 10 times of a number

To get one tenth of a number, divide the number by 10.

For example to get one – tenth of 100, divide it by 10, we get 10 as a result.

$\frac{1}{10} \times 100 = 10$

To get ten times of a number, multiply the number by 10

For example 10 times of 10 = 10 x 10 = 100

Hence apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.
