2.85:5
multiply each side by 8/5
4.56:8
so it is $4.56 for 8 cookies
4x-5y=6 for y
Solve the equation for the specified variable
Answer:
[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
Hope this makes sense. Also please tell me if I'm wrong and I'll be happy to look at it again for ya :)

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,
What is the percentage?
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.

what is the probability of rolling a product less than 5 on a pair of 6-sided dice
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

Find the 10th term for this geometric sequence
Answer:
0.0234375
Step-by-step explanation:
You just keep dividing by 2
If I'm wrong, sorry
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)

Jazelle Momba wants to visit her family in Zimbabwe in 2025, which is 6 years from now. She knows that it will cost approximately $8,000 including flight costs, on-the-ground costs, and extra spending money to stay for 4 months. If she opens an account that compounds interest at 4% semiannually, how much does she need to deposit today to cover the total cost of her visit?
9514 1404 393
Answer:
$6307.95
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
Momba needs to deposit $6307.95 today to have $8000 in 6 years.

he product of two whole numbers is 864 and their sum is 60 . What are the two numbers?
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

2 log x - log y - 2 log z as a single logarithm
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))
Answer:
[tex]log\frac{x^2}{yz^2}[/tex]
Step-by-step explanation:
Simplify 2log(x) by moving 2
inside the logarithm.
Simplify 2log(x) by moving 2
inside the logarithm.
log(x^2)−log(y)−2log(z)
Simplify −2log(z)
by moving 2
inside the logarithm.
log(x^2)−log(y)−log(z^2)
Use the quotient property of logarithms, logb (x)−logb (y)=logb (x/y)
[tex]log\frac{x^2}{y} - log(z^2)[/tex]
Use the quotient property of logarithms, logb(x)−logb(y)=logb (x/y)
[tex]log (\frac{x}{y})/( \frac{1}{z^2}}][/tex]
Multiply the numerator by the reciprocal of the denominator.
[tex]log\frac{x^2\\ }{y}.\frac{1}{z^2}[/tex]
Combine.
[tex]log\frac{x^2*1\\ }{yz^2}[/tex]
Multiply [tex]x^{2}[/tex] by 1
[tex]log\frac{x^2}{yz^2}[/tex]

Brittany brought her collection of Map Mosaics jigsaw puzzles to a secondhand store to sell. She was paid cash for all 8 puzzles in her collection. Before she left, Brittany used $7.25 of her earnings to purchase a used board game. She had $12.75 remaining. Which equation can you use to find the amount of money, p, Brittany received for each puzzle in her collection?
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.
What is the equation?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.
