Where do I put one set of parentheses in this equation?
Answer:
You could put a set of parentheses around [tex]8^{2}[/tex] ÷ [tex]4[/tex]
Step-by-step explanation:

Write the equation of the line, in slope intercept form, that goes through the points (6,4) and (-3,-5)
Answer:
y = x - 2
Step-by-step explanation:
Find the slope using rise over run
(y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-5 - 4) / (-3 - 6)
-9 / -9
= 1
Using y = mx + b, plug in the slope and a point to solve for b:
y = mx + b
4 = 1(6) + b
4 = 6 + b
-2 = b
Plug in the slope and b to y = mx + b
y = 1x - 2
y = x - 2
So, the equation of the line is y = x - 2

If you pay $7 for 3 tickets how much would 24 tickets cost?
Answer:
24 tickets would cost about $55.92
Step-by-step explanation:
To solve this equation I decided to figure out how much one ticket cost. I divided 7 by 3 and got 2.333333 I rounded that to one ticket costing $2.33. I then multiplied 2.33 by 24. 24 x 2.33= 55.92.
The reason I multiplied 24 by 2.33 is because the cost of one ticket is $2.33 so if I wanted to buy 24 tickets, I would have to multiply in order to find out the total cost.
I hope that this answer helped :D
Answer:
24 tickets would cost $56
Step-by-step explanation:
You would Convert it to a decimal by dividing the numerator by the denominator. 7/3*24=$56
3 tickets cost=$7
1 ticket cost= 7/3=$7/3

which of the following word problems can be solved using the inequality 9x+18>72
Step-by-step explanation:
In this question, I see an outlier. Most of the time you may want to solve the inequality, but check how the answers are phrased in relation to the inequality. The equation shows a > symbol.
Answer A states, "save at least $72." If the inequality used a greater than or equal to sign this could work, yet it uses a > symbol. I would go with B & C, if you haven't chosen already.
It takes a bear 9 more days to eat a barrel of honey alone than it takes the bear and a second bear to eat the barrel of honey together. It takes the first bear 7 fewer days to eat a barrel of honey alone than it takes the second bear to eat a barrel of honey alone. In how many days can the two bears eat a barrel of honey together?
Answer:
it takes the bears 12 days to eat honey together.
Step-by-step explanation:
1/x+9+1/x+16=1/x
(solve this using cross multiplication)
= x^2 = 144
x=12
The number of days that it takes for both of the considered bears to eat a barrel of honey together is 12 days.
How are number of people to time needed to complete a task related?More people to do a task means less time it will take.
Less people to do a task means more time it will take.
Thus, they are inversely related.
We can define a constant as "Manpower" needed for doing that specific work.
Each worker has his/her own strength. That strength is applied per unit of time.
Let we define:
Manpower needed for a work = time taken for that work × strength used for that work per unit of time
(we used multiplication as it represents linear use of strength to finish the task, so using that strength for a finite units of time means you stacked up your strengths that many times to finish that work)
Here, we have:
Instead of people, here we consider bears.Work in consideration = eating honey out of a considered barrel (assuming all barrels considered will have same amount of honey)Assume that:
Strength of first bear (call it bear A) for eating honey = S per day (as unit of time is a day here).Strength of second bear (call it bear B) for eating honey = T per dayManpower the work needs be M (assume)Time needed by bear A to complete the work = 'x' daysTime needed by bear B to complete the work = 'y' days.Then, we get:
Manpower needed for a work = time taken for that work × strength used for that work per unit of time
[tex]M = x \times S\\M = y \times T[/tex]
If bear A and bear B both do the work together, then their strenghts will add up.
That means, the combined strength would be S + T per day
The manpower the work needs is still M, therefore, the time needed is:
[tex]M = \text{Time needed} \times (S + T)\\\\\text{Time needed} = \dfrac{M}{S+T}[/tex]
This is the time needed for both bears to do the work together.
Also, it is given that:
It takes a bear 9 more days to eat a barrel of honey alone than it takes the bear and a second bear to eat the barrel of honey together.
or
Time needed by bear A to do work = 9 + time needed by both bears to do the work
or
[tex]x = 9 + \dfrac{M}{S + T}[/tex]
Also, it is given that:
It takes the first bear 7 fewer days to eat a barrel of honey alone than it takes the second bear to eat a barrel of honey alone.
or
Time taken by bear A to do the work = Time taken by bear B for that work - 7 days
or
[tex]x = y - 7[/tex]
Thus, we got these equations:
[tex]M = S \times x\\M = T \times y\\\\x = \dfrac{M}{S + T} +9\\\\x = y - 7[/tex]
call them first, second, third and fourth equation as per their ordering.
From the first and second equation, we get:
[tex]S = \dfrac{M}{x}\\\\T = \dfrac{M}{y}[/tex]
Putting these values in the third equation, we get:
[tex]x = \dfrac{M}{M/x + M/y} + 9\\\\\\x = \dfrac{xy}{x+y} + 9\\\\(x-9)(x+y) = xy\\x^2 -9x -9y + xy = xy\\x^2 -9x = 9y[/tex]
From the fourth equation, we know that:
[tex]x = y - 7[/tex]
or [tex]y = x +7[/tex]
Putting this value of y in the equation [tex]x^2 -9x = 9y[/tex], we get:
[tex]x^2 -9x = 9(x+7)\\x^2 -9x = 9x + 63\\x^2 -18x -63 =0\\\\x^2 -21x + 3x -63 = 0\\x(x-21) + 3(x - 21) = 0\\(x+3)(x-21) = 0\\(x+3) = 0, (x-21) = 0\\x = -3, x = 21[/tex]
'x' represents time in number of days. So it cannot be negative.
Thus, the value of x obtained is 21.
Also, we need: Time needed for both the bears to do the work together.
This time is the value of [tex]\dfrac{M}{S+T}[/tex], which is equal to [tex]x - 9[/tex] days (from the third equation)
Thus, the time needed for both the bears to do the work together = [tex]x-9 = 21-9 = 12 \; \rm days[/tex]
Thus, the number of days that it takes for both of the considered bears to eat a barrel of honey together is 12 days.

This question is so hard
Any number times one equals itself, and any number multiplied by two equals itself plus itself, so 1*2=2 and 1*2=1+1. The transitive property of equality states that if x=y and y=z then x=z. Since both 1+1 and 2 are equal to 1*2, they must be equal to each other, so 1+1=2.
The answer is 2
Six less than twice a number x is four
Answer:
2 x − 6
Explanation:
"Six less than.." means "Subtract 6 from".
Do not confuse this with "Six less..." which means "Subtract from 6".
Confusing, I know.
We know that "Double a number" means
2 x , where x is your mystery number.
Therefore, we have:
2 x − 6 , which translates to "6 less than 2x" or "6 less than twice a number"

Answer:
180° (in place of blank)
Step-by-step explanation:
GIVEN :-
∠D = 127°∠A = 75°PROCEDURE :-
∠C & ∠D are linear pair. (∵ They lie on same line)
⇒ ∠C + ∠D = 180°
⇒ ∠C = 180° - 127°
In a triangle , sum of its all interior angles equals to 180° (which is also known as "Angle Sum Property). So,
∠A + ∠B + ∠C = 180°
⇒ 75° + ∠B + (180° - 127°) = 180°
⇒ ∠B = 180° - 75° - (180° - 127°)

Answer:
y = 45 / 2x + 50
Step-by-step explanation:
The best equation for the line of the best fit would be y = 45 / 2x + 50.
The slope would be 45 / 2 and the y-intercept would be ( 0 , 50 ).
I used the points, ( 0 , 50 ) and ( 4 , 140 ) to get the equation, slope, and the y-intercept.
I used those points because they were the most accurate ones that I know for now.
Also, remember the formula is, "y = mx + b."
