The sum of three consecutive even integers is 486. Find all three integers.​

Answers

Answer:

161 + 162 + 163 = 486

Step-by-step explanation:

(X) + (X + 1) + (X + 2) = 486

X + X + 1 + X + 2 = 486

3X + 3 = 486

3X + 3 - 3 = 486 - 3

3X = 483

3X/3 = 483/3

There is a guitar that originally costs $249.99. It is on sale for 15% off. You also have to pay 6% sales tax. How much will you pay for the guitar? Please show work!!!

Answers

Answer:

225.24099

Step-by-step explanation:

249.99(0.15) = 37.4985

249.99 - 37.4985 = 212.4915

212.4915(0.06) = 12.74949

212.4915 + 12.74949 = 225.24099

A beekeeper pays $30 to rent a booth at a farmers' market.
She charges $5 for each jar of honey. The graph shows this
situation, which is modeled by the equation y = 5x - 30.
Which of the following is true?
A. The value of x can be negative.
B. The value of y can be negative.
C. The value of x can be fractional.
D. The value of y cannot be zero.
X

Answers

Answer: The answer is A

Step-by-step explanation: because 5x-30= -150 because I looked it up

Answer:

B. The value of y can be negative.

Step-by-step explanation:

The value of y can be negative, which means the beekeeper wasn't able to sell a lot of jars that could compensate the amount he paid for the booth. It also means he didn't have any profit, rather, he incurred a loss.

For example, if the beekeeper sold only 5 jars of honey, the solution will look like this:

Let x be the number of jars of honey the beekeeper sold.

y = 5x - 30y = 5(5) - 30y = 25 - 30y = -5

This means that the beekeeper has a loss of $5.

8 (5 + 4n) + 11 = -5 (3 - 7n)

Answers

Answer:

n=1

Step-by-step explanation:

(5 + 4n) + 11 = -5 (3 - 7n)

5+4n+11=−5(3−7n)

simplify

4n+16=−5(3−7n)

expand

4n+16=−15+35n

regroup

4n+16=35n−15

subtract

16=35n−15−4n

simplify

16=31n−15

add

16+15=31n

simplify

31=31n

n=1

Hope this helps :)

(pls mark brainliest)

Answer:

n=22

Step-by-step explanation:

8 (5 + 4n) + 11 = -5 (3 - 7n)

distribute

=> 40+32n+11=-15+45n

add like terms

=> 51+32n=-15+35n

subtract 35n on both sides and subtract 51 on both sides

32n-35n=-15-51

add like terms

-3n=-66

divide both sides by -3

n=22

What is a function?

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

g(x) = 10 - 2x

For x = 7,

g(7) = 10 - 2 x 7

g(7) = 10 - 14

g(7) = -4

Thus,

g(7) = -4.

Mariah has a spinner that has 10 equal sections, each containing a different number from 1 to 10. Mariah determines about how many times the spinner will land on a number that is greater than 7 in 250 spins, and her work is shown below.

P (number greater than 7) = StartFraction Number greater than 7 over Total number of sections EndFraction times number of spins = StartFraction 4 over 10 EndFraction (250) = 100.

What mistake did Mariah make, if any?
Mariah has the formula reversed; it should be the total number of sections over the numbers greater than 7.
Mariah should have used a 3 in the numerator because there are 3 numbers greater than 7.
Mariah should multiply by the number of sections in the spinner rather than the total number of spins.
Mariah calculated the prediction correctly and did not make any mistakes.

Show how to rewrite 1/5 with the denominator 10

Answers

The denominator is the bottom number.

To change the 5 to 10, you would multiply 5 by 2: 5 x 2 = 10

Because you multiplied the 5 by 2, you also need to multiply the numerator ( top number) by the same amount.

1 x 2 = 2

So 1/5 = 2/10

The answer is 2/10

A biologist studied the frequency of croaks for frogs from two different regions. From a random sample of 32 frogs located in the northern region, the mean number of croaks per hour was 21.3, and from a random sample of 38 frogs located in the southern region, the mean number of croaks per hour was 28.9. To estimate the difference in the mean number of croaks (southern minus northern), a 95 percent confidence interval was constructed from the samples. The interval was reported as (7.1, 8.1). Which of the following claims is supported by the interval? A. All southern frogs croak more times per hour than do all northern frogs. B. The northern frogs are likely to have a greater mean number of croaks per hour than the southern frogs. C. The southern frogs are likely to have a greater mean number of croaks per hour than the northern frogs. D. All frogs in the study have about the same number of croaks per hour. E.
