7c+5=9(c−3)
Answer:
c = 16
Step-by-step explanation:
First, distribute the 9 to the parentheses:
7c + 5 = 9(c − 3)
7c + 5 = 9c - 27
Then, subtract 7c from both sides:
5 = 2c - 27
Add 27 to both sides:
32 = 2c
Divide each side by 2:
16 = c
So, c = 16

C: Those who like Hamburgers but not burritos.
Step-by-step explanation:
Like Hamburgers ↓ Does Not Like Hamburgers↓ Total↓
Likes burritos → 39 38 77
Does not like burritos → 95 33 128
Total → 134 71 205
So, according to the above table, a total of 77 customers like burritos, out of which 38 do not like hamburgers, hence, the remaining 39 like Hamburgers.A total of 128 customers do not like burritos, out of which 95 do like hamburgers, hence, the remaining 33 do not like Hamburgers.A total of 134 customers like hamburgers, but 71 do not like it, hence, the total respondents are 205.Part A: The percent of respondents who do not like hamburgers and burritos both
There are 33 such respondents.
Hence, percentage 33/205 * 100 = 16.09%
Part B: Marginal relative frequency of all customers that like hamburgers
It will be the ratio of the sum of the customers that like hamburgers to the total number of respondents
Hence, ratio 134/205 = 0.65
Part C: The data point that has the strongest association of its two factors.
For this, we need to find the ratio of all the four data with the total.
Those who like Hamburgers and burritos: 39/134 = 0.29
Those who like Hamburgers but not burritos: 95/134 = 0.71
Those who like burritos but not Hamburgers: 38/71 = 0.53
Those who do not like burritos or Hamburgers: 33/71 = 0.47
So, the answer is those who like Hamburgers but not burritos.
Given a geometric sequence with a1=5 and a4=135 find a2.
Answer:
15
Step-by-step explanation:
Terms in a geometric series that are n apart will have a ratio that is r^n. Here we have terms a4 and a1, which are 4-1=3 apart, so their ratio is ...
a4/a1 = 135/5 = 27 = r^3
r = ∛27 = 3
The second term is the first, multiplied by this common ratio:
a2 = a1·r = 3(5)
a2 = 15
What is the equation of the line that passes through the point (5,8) and has a slope
of 3/5?
Answer:
[tex]y=\frac{3}{5}x+5[/tex]
Step-by-step explanation:
The equation for a line in slope-intercept form is:
[tex]y=mx+b[/tex]
Let's go through what each variable represents:
"y": y-coordinate for any point on the line
"m": slope of the line
"x": x-coordinate for any point on the line
"b": y-intercept (where the line intercepts the y-axis; represented by only the y-coordinate since the x-coordinate is 0)
Given:
Slope = 3/5
Passes through point (5, 8) --> x = 5, y = 8
Find:
y-intercept
We have determined what the question has given us, and what we need to find. Now, we can substitute the given values into the equation:
[tex]y=mx+b\\8=\frac{3}{5}(5)+b\\8=\frac{15}{5}+b\\8=3+b\\$Subtract 3 from both sides\\$b=5[/tex]
Therefore the equation of the line is:
[tex]y=\frac{3}{5}x+5[/tex]

If two sides in one triangle are 9 and 21 , then the third side might be
a) 9
b) 11
c) 12
d) 13
please explain how you got the answer in details I'm completely lost
Answer:
13
Step-by-step explanation:
there is a rule that says that if you add any 2 sides, it should be more than the third. 9+21 is greater than 13. 21+13 is greater than 9. 13 is the only number which if you add 9 to it it will be greater than 21. 12 will equal 21, but it still wont work.

What is the answer to this quadratic equation: 6x² + 11x – 35
Answer:
Step-by-step explanation:
This thing looks like you have to use the quadratic equation to solve it. You don't. It will factor. but you might have to guess a bit.
(3x )(2x )
(3x - 5 ) (2x + 7) How lucky is that!!?
Remove the Brackets
3x * 2x + 3x*7 - 5*2x - 35 Combine
2x*3x^2 + 21x - 10x - 35
6x^2 + 11x - 35
So the guess turns out to be correct. Now we need to solve for the roots.
3x - 5 = 0 Add 5 to both sides.
3x = 5 Divide by 3
x = 5/3
x = 1.6667
2x + 7 = 0 Subtract 7 from both sides
2x = - 7 Divide by 2
2x/2 = - 7/2
x = - 3.5
Answer
x = 1.667 orx = - 3.5

selling price of the lamp?
Answer:$24
Step-by-step explanation:
To find 20 percent of a number you multiply the number by 20, then multiply the answer by .01.
120 x 20 = 2400
2400 x .01 = 24
Answer: I think its 24 tell me if I'm wrong
20 divided by 100 gives you 0.2

A situation arises in which I am able to split $100 with you if we both agree to the split. If we do not both agree, nobody gets any money. The catch is I get to decide what the split is going to be before we make our decision. I tell you, the split will be Mr. Wright getting $99 and you only getting $1. Are you going to agree to the split or nah? Why did you choose the decision you made? Do you think your decision is rational or logical? Why or why not?
Answer:
No, I would not take that because it is rational and it will not evenly split within all of the people.
Step-by-step explanation:
If Mr. Wright is getting 99% of the money, and you get 1%, would you take it?

1/3(y+7)=3(y−1)
Solve for y
Answer:
2
Step-by-step explanation:
multiplying each number by 1/3 gives
1/3y+7/3= 3y-3
3y-1/3y=7/3+3
8/3y=16/3
y=16/3÷8/3
y=16/3×3/8
y=2
The solution of the equation 1/3(y+7)=3(y−1) will be ; y = 2
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that the equation is 1/3(y+7)=3(y−1)
First, multiplying each number by 1/3 gives;
1/3y+7/3= 3y-3
3y-1/3y=7/3+3
8/3y=16/3
Cross multiplication;
y=16/3÷8/3
y=16/3×3/8
y=2
Therefore, the solution of the equation 1/3(y+7)=3(y−1) will be ; y = 2
