Answer:

X=18 4x=72 6x=108

Step-by-step explanation:

Since the diagonal side of the parallelogram from each side has the same angle, there are two 4x's and to 6x's. Adding them all together is 20x and a parallelograms angles always to add up to 360 degrees. So 360=20x so x=18 and 4×18=72 and 6×18=108.

A. 7.
B. 9
C. 37
D. 39

Answers

Answer with step-by-step explanation:

If we use the formula, we would get this:

f(8) = 3(8) - 2 = 24 - 2 = 22

f(5) = 3(5) - 2 = 15 - 2 = 13

22 - 13 = 9

3 (2n + 4) - 2 = 1 +5 (n + 1)​

Answers

Answer:

n = -4

Step-by-step explanation:

Start off by remembering PEMDAS which first P means parenthesis so use distributive property to multiply the 2n + 4 by the 3 in front of it and do the same to the n + 1 and multiply that by the 5 in front which turns your question into 6n+12-2=1+5n+5 so now i'd combine like terms on both sides which now gives you 6n + 10 = 5n +6 so now to get the n on one side i'm going to sub tact it from both sides doesnt matter which one you do but to make it easier i'd subtract the 5n from the 6n because the whole point is to solve for n and by doing that you'd already be getting it by itself. so now the question should look like n + 10 = 6 so subtract 10 from both sides to isolate the n and you get your answer n = -4

Answer:

N = - 4

Step-by-step explanation:

3 (2n+4)-2=1+5(n+1

distribute 3 through the paretheses

6n+12-2=1+5n

add the numbers

6n+10=6+5n

move constant to the right-hand side and change its sign

6n-5n=6-10

calculate the difference

n = - 4

Problem 2:

Priya is walking down a long hallway. She walks halfway and stops. Then, she walks half of the remaining distance, and

stops again. She continues to stop every time she goes half of the remaining distance.

1. What fraction of the length of the hallway will Priya have covered after she starts and stops two times?

2. What fraction of the length of the hallway will Priya have covered after she starts and stops four times?

3. Will Priya ever reach the end of the hallway, repeatedly starting and stopping at half the remaining distance? Explain

your thinking.

Answers

Answer:

The answers to the questions about problem 2 are:

The fraction of the length after Priya stops two times is 3/4.The fraction of the length after Priya stops four times is 15/16.Priya will never reach the end of the hallway.

Step-by-step explanation:

The explanation about each answer is below:

1. In the first stop, Priya has walked half of the total length, and there would still be half the hallway, however, when she stops the second time, she has walked the half of the half, I mean:

[tex]\frac{1}{2}/2=\frac{1}{4}[/tex]

If you add the two values you obtain the total distance traveled by Priya:

[tex]\frac{1}{2}+\frac{1}{4}= \frac{3}{4}[/tex]

And the distance traveled in two stops is 3/4 of the total length of the hallway.

2. With four stops the system is the same, we know with two stops Priya travels 3/4 of the hallway, now with the third stop, she will travel half of the remaining distance:

[tex]\frac{1}{4}/2=\frac{1}{8}[/tex]

And in the fourth stop she will travel half of the remaining, I mean:

[tex]\frac{1}{8}/2=\frac{1}{16}[/tex]

Now, we add all the values of the distances obtained:

[tex]\frac{3}{4}+\frac{1}{8}+\frac{1}{16}= \frac{15}{16}[/tex]

So, the distance traveled by Priya in the fourth stop is 15/16 of the total length of the hallway.

3. How we know, the numbers are infinite, in the same forms the distances, by this reason, how the problem says that Priya walks just half of the distance, she will never reach the end because despite she has very near of the end, she will continue walking just half and ever smaller distances.

Michael is paid $9 per hour to work at the movie theater and $7 per hour when he helps his aunt at her bakery. Michael cannot work more than 32 hours in a week, but he wishes to earn at least $251 each week. Which weekly work schedule is within Michael’s constraints?

Answers

Answer:

The first one/$9 an hour job.

Step-by-step explanation:

For every 32 hours he works at the $9 per hour job he makes $288.

On the other hand, for every 32 hours he works at the $7 per hour job he only makes $224.

So the only one that'll work where he gets at least $251 is the $9 an hour job.

Hope this helps and have a nice day!
