Answer:

  C:  3/4x + 3/4 + 3/4 + 2/4x

Step-by-step explanation:

The various expressions simplify to ...

  given: 5/4x +6/4

  A: 46/4x

  B: 2/4x +6/4

  C: 5/4x +6/4

  D: 2/4x +11

Answer:

Step-by-step explanation:

xy = 864

x + y = 60                     Solve for y in the second equation

y = 60 - x                      

x * (60 - x) = 864          Remove the brackets.

60x - x^2 = 864           Put in order of powers and subtract 864

-x^2 + 60x - 864 =0    Multiply through by -1

x^2 - 60x + 864 = 0

This factors

(x - 36)(x - 24) = 0

Either

x - 36 = 0    in which case

x = 36

or

x - 24 = 0

x = 24

The two numbers are x = 36 and y = 24

of x = 24 and y = 36

Answer:

94

Step-by-step explanation:

Answer:

2/3 probability

Step-by-step explanation:

less than 5 is 4. There are 6 sides, so its 4/6. 4 out of 6 simplifies to 2/3.

Answer:

as there are 2 six-sided dices so total cases = 6*6 = 36

products less than 5 are = (1,1) , (1, 2), (1, 3), (2,1), (2,2), (3,1)

so number of products less than 5 = 6

so the probability = 6/36 = 1/6

Answer:

0.046875 aka 3/64

Step-by-step explanation:

In a geometric sequence, each term will be related to the previous term by undergoing either multiplication or division.

In this case, each case is exactly 1/2 of the previous term. 12 is half of 24, and 6 is half of 12. By continuing this sequence, we get

1: 24

2: 12 (24 * 1/2)

3: 6 (12 * 1/2)

4: 3 (6 * 1/2)

5: 3/2 (3 * 1/2)

6: 3/4 (3/2 * 1/2)

7. 3/8 (3/4 * 1/2)

8. 3/16 (3/8 * 1/2)

9. 3/32 (3/16 * 1/2)

10. 3/64 (3/32 * 1/2)

Answer:

33

Step-by-step explanation:

First, you need to put it in numerical order: 16, 24, 33, 36, 49

Next, find the number in the MIDDLE of it, which would be 33.

So, the answer is 33.

Answer:

maybe always true because that is number

The sum of rational number and irrational number always be an Irrational number

O Always true

The 75 exhibits are in the reptile house.

we have given that,

A volunteer at the zoo is responsible for feeding the animals in 15 exhibits in the reptile house.

We have to determine how many exhibits are in the reptile house.

Therefore we have

if 15 exhibits = 20% of total exhibits,

A percentage is a number or ratio expressed as a fraction of 100.

then 15/20% = 75 total exhibits in the reptile house

We can check the answer,

75 x 20% = 15

Therefore the 75 exhibits are in the reptile house.

Answer:

[tex]p=(12.75+7.25)/8[/tex]

Step-by-step explanation:

The money she earned is the remaining money plus the board game price. With the total profit, you divide by the 8 puzzles

Brittany received an amount of $2.50 for each puzzle in her collection.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let's assume the amount of money Brittany received for each puzzle in her collection is p dollars.

Then the total amount of money she received for 8 puzzles will be 8p dollars.

If she used $7.25 to buy a board game, then the amount of money she had before purchasing the board game was 12.75 + 7.25 = $20.

We know that the total amount of money Brittany received for 8 puzzles was 8p dollars. So we can write an equation:

8p = 20

Divide both sides by 8:

p = 2.5

Therefore, he received $2.50 for each puzzle in her collection.

Step-by-step explanation:

The compound interest formula can help with that.

  A = P(1 +r/n)^(nt) . . . . value of principal P at rate r for t years, compounded n times per year.

  P = A(1 +r/n)^(-nt) = $8000(1 +0.04/2)^(-2·6) = $8000(1.02^-12) = $6307.95

Answer:

log ( x^2/(yz^2))

Step-by-step explanation:

2 log x - log y - 2 log z

We know a log b = log b^a

Rewriting

2 log x = log x^2  and 2 log z = log z^2

log x^2 - log y -  log z^2

Rewriting

log x^2 - (log y +  log z^2)

We know that log a + log b = log (a*b)

log x^2 - (log (y z^2))

And we know log a - log b = log (a/b)

log ( x^2/(yz^2))

[tex]y = - \frac{4}{5} x + \frac{6}{5} [/tex]

Step-by-step explanation:

First subtract 4x on both sides in order to get -5y alone. Now you have -5y = 4x + 6 (since neither 6 nor 4x are like terms). Now divide -5 on both sides in order to get rid of it, so we can get y by its self. Now you have y = -4/5 x + 6/5
