Answer/Step-by-step Explanation:

Given:

a = no. of DVDs

b = no. of CDs

Total cost ($) for DVDs and CDs = [tex] 2.5a + 2b [/tex]

a. The cost for 1 DVD = 2.5(a) = 2.5(1) = $2.5

The cost for 1 CD = 2(b) = 2(1) = $2

b. Total cost for 4 DVDs and 4 CDs:

Substitute a = 4, and b = 4 into the equation.

[tex] 2.5(4) + 2(4) [/tex]

[tex] 10 + 8 = 18 [/tex]

Total cost for 4 DVDs and 4 CDs = $18

c. To find out if $20 would be enough to buy 6 DVDs and 3 CDs, substitute a = 6, and b = 3 into the equation. Solve for the total cost to see if it equals $20 or is less than $20. If it's greater than $20, then it won't be enough.

[tex] 2.5(6) + 2(3) [/tex]

[tex] 15 + 6 = 21 [/tex]

6 DVDs and 3 CDs cost more than $20, therefore, $20 is not enough.

Answer:

r = 8

Step-by-step explanation:

you start by distributing the 5 to r and -7 to get 3 over 5r - 37. You can then multiply both sides by 5r-37 to get 3 = 5r-37. From here you can add 37 to both sides to get 40 = 5r. From there you divide both sides by 5 to get r = 8

r= 8

p = 1/8

Step-by-step explanation:

Hi there !

⁸⁾-3p + 1/8 = ²⁾- 1/4

- 24p + 1 = - 2

- 24p = - 2 - 1

- 24p = - 3 | (-)

24p = 3

p = 3⁽³/24

p = 1/8

Answer:

[tex]T_n = 7.143(0.7^n)[/tex]

Step-by-step explanation:

If a ball bounces to a height of 5feet, the initial drop = 5feet

If the ball rebounds to 70% of its previous height after each bounce, the next height after rebouncing will be expressed as;

= 70% of 5

= 70/100 * 5

= 0.7*5

= 3.5 feet

The next height will be 0.7*3.75 = 2.45 and so on

The  heights wil form a sequence as thus;

5, 3.5, 2.45...

This sequence forms a geometric progression.

To get the function that could be used to model the nth term in the sequence of heights of the ball after the initial drop, w will find the nth term of the sequence

[tex]T_n = ar^{n-1}[/tex]

a is the first term of the sequence

n is the number of terms

r is the common ratio

From the sequence:

a = 5

[tex]r = \frac{3.5}{5} = \frac{2.75}{3.5} = 0.7[/tex]

Substitute the given values into the formula

[tex]T_n = 5(0.7)^{n-1}\\T_n = 5(\frac{0.7^n}{0.7^1} )\\T_n = \frac{5}{0.7}\times 0.7^n \\T_n = 7.143(0.7^n)[/tex]

The nth tern=m required is [tex]T_n = 7.143(0.7^n)[/tex]

Answer: 15, and 44 are integers.

Step-by-step explanation: For 15 to be an integer, 15 has to be a whole number. Furthermore, for 15 to be an integer, you should be able to write 15 without a fractional or decimal component. 15 is a whole number that can be written without a fractional component, thus 15 is an integer, as well as 44.

Answer:

765

Step-by-step explanation:

   3

   17    Multiply 7x5 and 1x5 first. 7x5=35, so we move the 3 above 1 and

x 45    add it to the product of 1x5. 1x5=5+3=8

  85   Before we multiply 7x4 and 1x4, put a zero in the ones place.  

+680  7x4=28, so we move the 2 above 1 and add it to the product of 1x4.  

 765   1x4=4+2=6 Add the products, and 765 is the answer!!

Answer:

D: 3

Step-by-step explanation:

2 is not a factor of three

The number 3 can not be the common denominator for 2/3 and 1/2. The correct option is D.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. The number of components of a specific size is expressed as a fraction.

The fractions will have all the numbers 18, 12, and 6 as the common denominator but can not have 3 as a common denominator.

Therefore, the number 3 can not be the common denominator for 2/3 and 1/2. The correct option is D.

-27x+63

Step-by-step explanation:

you do -9 times 3x then -9 times -7, two negatives creates a positive, and so 9 times 7 equals 63

hope this helps :^)

-9(3x-7)

Multiply each term in the parentheses by -9

-9×3x-9×(-7)

Calculate the product

-27x-9×(-7)

now we do the same thing only different way ok

-9×3x

Multiplying a negative and a positive equals a negative : (-)x(+)=(-)

-(9×3)x

Multiply the numbers

-27x

-9×3x-9×(-7)

Multiply the numbers

-27x+63

Now we do the same thing only different way ok

-9×(-7)

Multiply two negatives equals a positive: (-)×(-)=(+)

c=11

=$11

therefore for 5 events

c=3(5)+8

c=15+8
