A music store is receiving a shipment of Ipads. Each box comes with 12 white, 12 black and 24 grey
Ipads. They already have 23 white, 16 black and 22 grey Ipads. If the store is receiving 5 boxes, how
many of each color Ipad will they have?

Answers

Answer:

142 Grey, 83 white, 76 black

Step-by-step explanation:

If you were to take 5 boxes and put 24,12,12 in each, then multiply each number by 5 you wpuld get 120 Grey, 60 white and 76 black. Then you would add what they already have 120 Grey + 22 Grey is 142 grey, 60 white + 23 white is 83 white, and 60 black + 16 black is 76 black.

What is the slope of a line perpendicular to Line AB given A (6,2) and B (-3,2)

Answers

Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m of AB using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = A(6, 2) and (x₂, y₂ ) = B(- 3, 2)

m = [tex]\frac{2-2}{-3-6}[/tex] = [tex]\frac{0}{-9}[/tex] = 0

A line with a slope of zero is a horizontal line, parallel to the x- axis.

Thus a line perpendicular to AB is a vertical line parallel to the y- axis.

The slope of a vertical line is undefined

A. m + s = 50
B. m + 2s = 20
C. m.s= 20
D. m + s = 20

Answers

Answer:

d) m + s = 20

m = 5

Step-by-step explanation:

m + 3s = 50

m + s = 20

m + 3(20-m) = 50

m + 60 - 3m = 50

60 - 2m = 50

60 = 50 + 2m

60 - 50 = 2m

10 = 2m

5 = m

Enzo and Beatrice are playing games at their local arcade incredibly ends wins five tickets from every game in the trees wins 11 tickets from every game when they stop playing games Enzo in the trees had won the same number of total tickets what is the minimum number of games that Enzo could have played

Answers

Answer:

22 games

Step-by-step explanation:

In order to find the minimum number of games that Enzo played we need to find the least common multiple of tickets where both Enzo and Beatrice are equal. To do this we simply find all the multiples of the number of games each could have played by the number of tickets per game until we find one in common.

5*1 = 5                   11*1 = 11

5*2 = 10                 11*2 = 22

5*3 = 15                  11*3 = 33

5*4 = 20                 11*4 = 44

5*5 = 25                 11*5 = 55

...                             ...

...                             ...

...                             ...

5*22 = 110               11*10 = 110

Finally, we can see that the minimum amount of games that Enzo needs to play in order for both Enzo and Beatrice to have the same amount of tickets is 22 games.

Which expression is equivalent to 2(a+3) when a=3?
O 2(3)
05(3)
O 2(3)+3
O 2(3)+6

Answers

Answer:

The answer is 2(3)+6

Step-by-step explanation:

The perenthesis means multiplication so you would first do 2 times three which is 6 and then 6+6=12 and the first expresion is 2(a+3) a=3 to solve that you would do whats in the perenthesis 3+3 which equals 6 and then the 6 in the perenthesis means mulitplication. so then you would do 2 times 6 and get 12. so the 3rd one is the answer.

identify the sequence 18,13,8,3,-2 PLZ HELPPPPP

Answers

The common difference between each term is -5. The nth term of the sequence as follows: aₙ = 18 - 5(n-1)

The given sequence is 18, 13, 8, 3, -2.

To identify the pattern in the sequence, we can observe that each term is decreasing by 5. Starting from 18, we subtract 5 to get the next term, and so on. The common difference between each term is -5.

Using this pattern, we can continue the sequence as follows:

-2 - 5 = -7

-7 - 5 = -12

-12 - 5 = -17

-17 - 5 = -22

The extended sequence would be -2, -7, -12, -17, -22.

In terms of the general formula, we can represent the nth term of the sequence as follows:

aₙ = 18 - 5(n-1)
