I'm sorry if any of these are wrong I didn't get to check them over.
Step-by-step explanation:
I will be substituting "a number" with the variable x.
1. Four more than twice a number is 8.
2x+4 = 8
2x = 4
x = 2
2. Three more than four times a number is 15.
4x+3 = 15
4x = 12
x = 3
3. Five less than twice a number is 7.
2x-5 = 7
2x = 12
x = 6
4. One less than four times a number is 11.
4x-1 = 11
4x = 12
x = 3
5. Seven more than the quotient of a number and 2 is 10.
(x/2)+7 = 10
(x/2) = 3
x = 6
6. Six less than six times a number is 12.
6x-6 = 12
6x = 18
x = 3
7. Five less than the quotient of a number and 3 is -7.
(x/3)-5 = -7
x/3 = -2
x = -6
8. Seven more than twice a number is 1.
2x+7 = 1
2x = -6
x = -3
9. The difference between 5 times a number and 3 is 12.
5x-3 = 12
5x = 15
x = 3
10. Nine more than 3 times a number is -6.
3x+9 = -6
3x = -15
x = -5
11. Nine more than the quotient of a number and 4 is 12.
(x/4)+9 = 12
x/4 = 3
x = 12
12. Four less than the quotient of a number and 3 is -10.
(x/3)-4 = -10
x/3 = -6
x = -18
13. Nine less than six times a number is -15.
6x-9 = -15
6x = -6
x = -1

x=4
Answer:
x = 4
Step-by-step explanation:
Vertically opposite angles are equal
27x + 2 = 26x + 6 {Subtract 26x from both sides}
27x -26x + 2 = 6
x + 2 = 6 {Subtract 2 form both sides}
x = 6 - 2

Bryan earns $5.00 per lawn mowed and $5.00 per car washed. Let m be the number of lawns mowed and let c be the number of cars washed. Select
all the expressions that could represent the total earned, E in dollars, by Bryan.
E = 5m + c
E = 5(m + C)
E = 5 + mc
E = 5m + 50
E = 5c + m
Answers
Answer:
E=5(m+c)
Step-by-step explanation:
Since Bryan earns $5 for every lawn mowed, the equation right now is 5m. We have to add the $5 for the cars washed, 5c.
5m+5cThat can be factored, 5(m+c)Answer

American Airlines charges $270 for a flight to Denver and $50 for each piece of luggage. Delta Airlines charges $330 for a flight and only $30 for each piece of luggage. Which inequality shows the number of pieces of luggage that need to be checked for American Airlines to cost more than Delta Airines for a flight to Denver?
F 270 + 50x > 330 + 30x
G 270x +50 > 330x + 30
H 270x + 50 < 330x +30
J 270 +50x > 330 + 30x
Answers
Answer:
J; 250 + 50x > 330 + 30x
Step-by-step explanation:
Since we don't have to worry about formatting the numbers to slope-intercept form, we can start the process of elimination.
First, we can disregard G and H because both have the x in the wrong place:
—> F 270 + 50x ≥ 330 + 30x
—> G 270x + 50 > 330x + 30
—> H 270x + 50 < 330x +30
—> J 270 + 50x > 330 + 30x
We're looking for 270 + 50x > 330 + 30x.
Next, we determine which symbols are correct. Since the question is only asking for when American Airlines would be more expensive, not when it would be just as much or more, we can get rid of F.
—> F 270 + 50x ≥ 330 + 30x
—> J 270 +50x > 330 + 30x
We finally have our answer, J.

Living with parents: The Pew Research Center reported that 36% of American Millennials (adults ages 18-31) stll live at home with their parents. A group of students wants to conduct a study to determine whether this result is true for students at their campus. They survey 300 randomly selected students at their campus and determine that 43% of them live at home with their parents. With this data, they test the following hypotheses at the 5% significance level. The P-value is 0.006. H0: Of Millennial students at their campus, 36% live at home with their parents. Ha: More than 36% of Millennial students at their campus live at home with their parents What assumption about the sample underlies the hypothesis test? A. The sample comes from a population of Millennial students at their campus where 36% still live at home with their parents. B.

[tex]\mathbf{The \ sample \ comes \ from \ a \ population \ of \ Millennial \ students }[/tex] [tex]\mathbf{at \ their \ campus\ where \ 3 6\%\ still\ live\ at\ home\ with\ their \ parents}[/tex]
Step-by-step explanation:
From the given information.
The proportion of American Millennials still with their parents = 0.36
The sample size = 300
Sample proportion = 0.43
Level of significance = 0.006
P-value = 0.006
Null hypothesis:
[tex]\mathbf{H_o: Of \ Millennial \ students \ at \ their \ campus, \ 36\% \ }[/tex][tex]\mathbf{ live \ at \ some \ with \ their \ parents . }[/tex]
[tex]\mathbf{H_a: More \ than \ 36\% \ of \ Millennial \ students \ at \ their \ campus \ live \ at \ home }[/tex][tex]\mathbf{ \ with \ their \ parents}[/tex]
The required task is to determine the assumption about the sample that underlies the hypothesis test from the given options.

8(-8x – 6) = -6x - 22
solve for x
Answers
Answer:
x = - 13/29 OR x = - -0.44827586
Step-by-step explanation:
We use PEMDAS to evaluate the equation.
P stands for parenthesis. In this case we distribute the 8 to the equation in parenthesis.
8(-8x - 6)
-64x - 48 = -6x - 22 we will move the terms to their proportional sides
-64x + 6x = 22 + 48 (remember we do the opposite equation to move to the other side of the equals to sign)
-58x = 70 we divide both sides by -58 to isolate x
x = - 13/29 OR x = - -0.44827586
