Answer:

22.5 and 13.5 are the numbers. average of both numbers is 18.

Step-by-step explanation:

Given that there are two numbers.

let them be, x and y

using the unknown numbers,

make x the subject:

Solve them simultaneously:

Then another number, x:

Average:

Let the two numbers be x and y

x+y = 36 -----(1)

x - y = = 9-----(2)

(1)+(2)

x +y = 36

x - y = 9

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

2x = 45

x = 45/2

Then y =?

x - y =9

45/2 - y =9

y = 45/2-9

y = (45-18)/2

y = 27/2

The two numbers are 45/2 and 27/2

Answer:

Reggie has spent

Step-by-step explanation:

7 quarters

Answer:

7 quarters

Step-by-step explanation:

We know that for every quarter, Reggie would receive 50 food pebbles, we also know that he has thrown 350 food pebbles into fish pools. So let's create an equation, q is for the quarters.

50(q) = 350

Since every quarter gives Reggie 50 food pebbles, then the q variable will go next to 50, and since we need to reach the total amount of 350, we put it on the opposite side.

Solve for q by isolating it, divide 50 from both sides:

[tex]\frac{50q}{50} =\frac{350}{50}[/tex]

[tex]q = 7[/tex]

Therefore, Reggie used 7 quarters for 350 food pebbles.

Answer:

20

Step-by-step explanation:

One angle of a nonagon has an angle of 140 degrees, so

7x = 140.

Divide 140 by 7 to find the value of x.

140 ÷ 7 = 20

Solution:

Simplify the distributive property and solve.

The solution to the equation is 15.

Your required solution :

Let us solve this equation..!!

Firstly multiplying 2 by (x - 2)

⇒ 2 × (x - 2) = 26

⇒ 2x - 4 = 26

On transposing -4 to R.H.S. it would be positive,

⇒ 2x = 26 + 4

⇒ 2x = 30

On dividing 30 by 2 we gets,

⇒ x = 30/2

⇒ x = 15

Therefore, value of x is 15.

A recursive sequence is a sequence of numbers whose values are determined by the numbers that come before them in the sequence.

We’re given a sequence whose (n + 1)-th term f(n + 1) depends on the value of the n-th term f(n), specified by the recursive rule

f(n + 1) = -4 f(n) + 3

We’re also given the 1st term in the sequence, f(1) = 1. Using this value and the recursive rule, we can find the next term f(2). (Just replace n with 1.)

f(1 + 1) = -4 f(1) + 3

f(2) = -4 • 1 + 3

f(2) = -1

We do the same thing to find the next term f(3) :

f(2 + 1) = -4 f(2) + 3

f(3) = -4 • (-1) + 3

f(3) = 7

One more time to find the next term f(4) :

f(3 + 1) = -4 f(3) + 3

f(4) = -4 • 7 + 3

f(4) = -25

Answer:

5/10

Step-by-step explanation:

1/2 times 5 equals 5/10, so they are equal.

Using it's concept, it is found that the probabilities are:

a. 0.7143 = 71.43% probability that is contains coffee or candy.

b. 0.4348 = 43.48% probability that it contains tea, given that it contain mugs.

c. 0.1558 = 15.58% probability it contains tea and cookies.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Item a:

There is a total of 20 + 13 + 10 + 12 + 10 + 12 = 77 baskets, of which 20 + 13 + 10 + 12 = 55 contain coffee or candy, hence:

[tex]p = \frac{55}{77} = 0.7143[/tex]

0.7143 = 71.43% probability that is contains coffee or candy.

Item b:

13 + 10 = 23 contain mugs, of which 10 contain tea, hence:

[tex]p = \frac{10}{23} = 0.4348[/tex]

0.4348 = 43.48% probability that it contains tea, given that it contain mugs.

Item c:

Out of the 77, 12 contain tea and cookies, hence:

[tex]p = \frac{12}{77} = 0.1558[/tex]

0.1558 = 15.58% probability it contains tea and cookies.

Answer/Step-by-step explanation:

If the vertical line touches the graph at more than one point, then the graph is not a function.Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function.

Yes it's a function

As per the defination of function.

If every domain of the relationship has an unique range that's a function

So

18 - x - 5 = for sue

(18 + x)/2 = for tony

to put the combined total together

18 - x - 5 + (18 + x)/2

well the X's cancel out since it stays between them

18 - 5 + (18)/2

18 - 5 + 9

Seven boys hire DVD's and each pays R5,50

I assume R 5.50 ( R to be the currency)

also assuming that they dont hire any more DVDs

total amount paid by 7 boys

= 5.50 × 7

= 38.5

when 4 more friends join the amount should get divided by 11 ( 7 + 4 )

so each has to pay an amount of 38.5 / 11 = 3.5

I think my assumptions here were correct

if not

let me know :)
