Answer:
z=(-6)
Step-by-step explanation:
(2/3)*z=(-4)
2*z=3*(-4) --> We move the 3 from the left to the right part of the equation. It was dividing, so we move it multiplying.
2*z=(-12)
z=(-12)/2 --> It's the inverse case of before. 2 was multiplying, so we move it to the right by dividing it.
z=(-6)

Jeri has a total of 40 pets with a total of 160 legs. If
she owns only cats and dogs, how many of each does
she have? Write a system of equations to represent
this situation. Solve it using any method.
Answers
Answer:
let x be the number of cats and y be the number of dogs:
x + y = 40
4x + 4y = 160
If you divide both sides of the second equation by 4, you will be left with:
x + y = 40
Then, subtract both equations:
x + y =40
- (x + y = 40)
0 = 0

George Martin loves The Beatles. Honestly, who doesn’t? On George’s favorite Spotify playlist, 40% of the songs are by The Beatles. During a long road trip, George shuffled his playlist and listened to 30 songs. What is the probability that at least half of the songs on the trip were by The Beatles? Don’t forget to check appropriate conditions before you do your computations. Note: you can assume the playlist is infinite in length.
Answers
Answer:
17.5%
Step-by-step explanation:
First of all, see this situation as a cumulative binomial distribution. You have isolated trials with a probability of success. This makes it binomial. The wording of the question "what is the probability of at least half..." makes this cumulative.
There are a few ways to calculate this, and I'm not quite sure which way you're familiar with. I'll show the cumbersome way and use wolfram to make the calculation.
First, I'll calculate the probability for 15 success, given 30 trials.
30c15*0.4^15*0.6^15
Since the question asks for the probability of at least 15 success, I'll have to make a calculation for the probability of 16 successes, then 17, and so on. Then I'll have to add all the probabilities together. So, I'll use wolfram for that (see attached)

Step-by-step explanation:
Given data
He paid $10 for parking and

4. Determine whether f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.
Write yes or no and explain your reasoning by showing work.
Answers
Answer:
YES! we conclude that f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.
Step-by-step explanation:
Given
Given that the function f(x) and g(x) are inverse functions.
[tex]f\left(x\right)\:=\:\frac{1}{3}x\:+\:5[/tex]
[tex]g(x) = 3x - 15[/tex]
To determine
Let us determine whether f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.
Determining the inverse function of f(x)
A function g is the inverse function of f if for y = f(x), x = g(y)
[tex]y=\frac{1}{3}x+5[/tex]
Replace x with y
[tex]x=\frac{1}{3}y+5[/tex]
Solve for y
[tex]y=3x-15[/tex]
Therefore,
YES! we conclude that f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.
Question 1
What value of v makes the
equation true?
5(5 + 5v) =-29 + 7v
Answers
Answer:
v = -3
Step-by-step explanation:
5 (5 + 5v) = -29 + 7v
or, 25 + 25 v = -29 + 7v
or, 25 + 29 = 7v - 25 v
or, 54 = - 18v
or, v = -54/18
or, v = -3
for checking ( putting the value of v in both sides )
5( 5 + 5 (-3))= -29 + 7 (-3)
or, 5 ( 5 - 15 ) = -29 -21
or, 5 (-10) = -50
or, -50 = - 50
the equation is true
hope it will help you ☺✌
Answer:
v = - 3
Step-by-step explanation:
Given
5(5 + 5v) = - 29 + 7v ← distribute parenthesis on left side
25 + 25v = - 29 + 7v ( subtract 7v from both sides )
25 + 18v = - 29 ( subtract 25 from both sides )
18v = - 54 ( divide both sides by 18 )
v = - 3

It loses -0.04 milliliters per minute.
Step-by-step explanation:
The pipe loses 1 1/5 milliliters (I'mma just call it ml from now on) every 30 minutes. The question is asking how many ml it loses every one minute. To find this, divide 1 1/5 ml by 30. This is very difficult with fractions tho, so convert the fraction into a decimal. (1 1/5 as a decimal is 1.2) Then divide 1.2 by 30 and you get -0.04 ml per minute.
Make sure you put that it loses *negative* 0.04 ml per minute!

b. increase operational capital with a bank loan
c. lower fixed expenses (phone, electric, advertising)
d. lower direct costs (labor, purchasing, controlling, inventory)
Answers
Answer:
b
Step-by-step explanation:
increase operational capital with a bank loan
Increase operational capital with a bank loan is not a recommendation the author of the Businesstown.com article makes to lower your break-even point.
What are Expenses?An expense is an item requiring an outflow of money, or any form of fortune in general, to another person or group as payment for an item, service, or other category of costs.
In the article from BusinessTown.com, the author recommends several strategies to lower the break-even point of a business, which is the point where total revenue equals total expenses. The lower the break-even point, the easier it is for a business to make a profit.
Increase operational capital with a bank loan is not a recommendation to lower the break-even point.
Instead, it suggests borrowing more money to finance operations, which can increase the break-even point and the amount of revenue needed to cover expenses.
Hence, increase operational capital with a bank loan is not a recommendation the author of the Businesstown.com article makes to lower your break-even point.
