-4+2(5k-6)=-3k-39
need it with the steps
Answers
1. Distributive property 2(5k-6) = 10k -12
2. Add 10k-12-4= - 3K -39 which is 10k-16= - 3K -39
3. Add to both sides 10k -16 +16 = 10k, -3k-39 + 16 = -3k-24, 10k = -3k-24
4. Add to both sides with variable
10k + 3k = 13k, -3k-24+3k = -24
5. Divide 13k/13 = -24/13
6. The answer k≈ −1.846153846153846

The first three terms of a geometric sequence are as follows.
2, 10, 50
Find the next two terms of this sequence.
Answers
Answer:
250, 1250
Step-by-step explanation:
Since 10/2 = 50/ 10 = 5, the common ratio = 5 So the next term in the sequence is found by multiplying the last term by 5.
Therefore, 50 x 5 = 250 and 250 x 5 = 1250. So, the next two terms in your sequence are 250 and 1250

The enrollment at a university increased from 1,000 students to 6,000 students over a 6-year period. What was the percent increase in enrollment over that time period?
Answers
Answer: 500%
Step-by-step explanation:
The percent increase is calculated as:
= (New number of students - Old number of students) / Old number of students * 100%
= (6,000 - 1,000) / 1,000 * 100%
= 5 * 100%
= 500%
Sixty percent, or 12, of the students in Alex's class are going to the movies. 2/3, or 14, of the students in Mary's class are going to the movies. Which class has more students? Justify your answer using equations.
Answers
Answer:
Mary's class.
Step-by-step explanation:
One way to do this is to figure out how many students are in Alex's class and how many students are in Mary's class.
60% of Alex's class is 12 students
[tex]\frac{12*100}{60}[/tex] = [tex]\frac{1200}{60}[/tex]= 20 students
[tex]\frac{2}{3}[/tex] or 66.66% (repeating) of Mary's class is 14 students
[tex]\frac{14*100}{66.66}[/tex] = [tex]\frac{1400}{66.66}[/tex] = 21 students
(^^66.66 repeating)
Mary's class has more students than Alex's class.

Answers
But then someone ate 1/3 of the peanuts, and the bag is now only 2/3 full.
This means that there is only two-thirds of the original 3/4 pound remaining now.
This can be simply solved by: 3/4 * 2/3 = 2/4 = 1/2 pound

Thank you!
Answers
Answer:
Step-by-step explanation:
1. The probability that your mail is delivered before 2 pm is 0.9, so the probability that the mail is delivered at 2 pm or after 2 pm (so not before 2 pm) is 1-0.9=0.1.
Remark: 0.9=9/10=90/100=90%, and 0.1 is 10%

A cell phone provider offers a plan that costs $40 per month plus $0.20 per text message sent or received. A comparable plan costs $70 per month but offers unlimited text messaging.
Answers
Answer:
For, 250 messages the plans cost the same. Under 250 messages, plan A is cheaper.
Step-by-step explanation:
Giving the following information:
Plan A:
Fixed costs= $40
Variable cost= $0.2
Plan B:
Fixed cost= $40
I assume that we have to determine the indifference point, where the two plans cost the same.
First, we need to establish the total cost equations
Plan A= 20 + 0.2x
Plan B= 70
x= number of messages
Now, we equal both formulas and isolate x:
20 + 0.2x = 70
0.2x= 50
x= 250
For, 250 messages the plans cost the same. Under 250 messages, plan A is cheaper.

Step-by-step explanation:
Colton has 888 comedy movies, 666 action movies, 555 fantasy movies, and 111 drama movie on his list of favorite movies. For every 555 movies on the list, there are 222 \_\_\_\_____\_, \_, \_, \_ movies.
Answers
Answer: Comedy
Step-by-step explanation:
Find out the percentages of each of the movies. First find the total quantity.
= 888 + 666 + 555 + 111
= 2,220 movies
Comedy = 888/2,220 * 100% = 40%
Action = 666 / 2,220 * 100% = 30%
Fantasy = 555/2,220 * 100% = 25%
Drama = 111/ 2,220 * 100% = 5%
222 movies out of 555 is:
= 222 / 555 * 100%
= 40%
222 movies out of 555 movies will therefore be comedy.
Answer:
222/555 are comedy

Given the relation y = 3x^2 + 1, if the input is 4, what is the output?
Answers
Answer:
Step-by-step explanation:
y=3(4)²+1
=48+1
=49
Answer:
The output is 49
Step-by-step explanation:
If the input is 4, then x = 4.
Replace x with 4 and you have the equation:
3(4)^2 + 1 = 49
Because Y is the output, and Y = 49, the output is 49

[tex]E(x) = 4.56[/tex] --- Mean
[tex]s^2 = 1.0944[/tex] --- Variance
[tex]s = 1.0461[/tex] --- Standard Deviation
Step-by-step explanation:
See Comment for missing details
Given
[tex]p = 0.76[/tex] --- proportion
[tex]n = 6[/tex] -- sample
Solving (a): The mean; E(x)
This is calculated as:
[tex]E(x) = n * p[/tex]
Substitute values for n and p
[tex]E(x) = 6 * 0.76[/tex]
[tex]E(x) = 4.56[/tex]
Solving (b): The variance; s^2
This is calculated as:
[tex]s^2 = n*p*(1-p)[/tex]
Substitute values for n and p
[tex]s^2 = 6 * 0.76 * (1-0.76)[/tex]
[tex]s^2 = 6 * 0.76 * 0.24[/tex]
[tex]s^2 = 1.0944[/tex]
Solving (c): The standard deviation; s
This is calculated as:
[tex]s = \sqrt{s^2[/tex]
Substitute value for s^2
[tex]s = \sqrt{1.0944[/tex]
[tex]s = 1.0461[/tex]
