At the annual high school carnival, Dalton sells popcorn for $4 a bag. His cost for setting up a booth is $20. Today, his goal is to make a profit of $500. How many bags of popcorn must he sell to make a profit of $500?
Hint: 500 = 4x - 20
Answer:
130=x
Step-by-step explanation: Do +20 on both sides the 20 on the left side cancels and 500 + 20= 520. Bring down the 4x. Divide 4 on both sides. 4 divided by 4 cancels. 520/4= 130. So he needs to sell 130. Give me brainliest.

Some friends spent a total of $12.00 on popcorn and drinks at the movie theater. A bucket of popcorn cost $2.00 and a drink cost $1.50.
A. Create an equation to represent the relationship between the number of buckets of popcorn, x, and the number of drinks, y, the friends bought for $12.00.
The friends bought 4 drinks.
B. How many buckets of popcorn did they buy?
Answer:
A. 12 = 2x + 1.5y
B. 3 buckets of popcorn
Step-by-step explanation:
We know 12 is the total and the cost for is $2 EACH we are multiplying so it would be written as 2x same goes for the drinks except it would be 1.50y
Since we found the equation is 12 = 2x + 1.5y and we are told that y represents the number of drinks we can replace y with 4. It would look like this,
12 = 2x + 1.5(4)
After you multiply 1.5 by 4 you get 6.
12 = 2x + 6
-6 -6
6 = 2x
Now divide both sides by 2, that way you isolate the variable.
6/2 = 3
2x/2 = x
So we are left with x = 3, which means if they buy 4 drinks they will buy 3 buckets of popcorn.

In a newspaper, it was reported that yearly robberies in Springfield were up 50%to 279 in 2012 from 2011. How many robberies were there in Springfield in 2011.
hi there! here's my answer for you...
There were 186 Springfield robberies in 2011.
hope this helped. i have included a step-by-step explanation below in case you need it. have a good one!
.
Think about what happens when you double a number.
You multiply it by 2. Since it's been doubles, we say is has had a 100% increase.
Likewise a 50% increase correlates to multiply by 1.5
Since we are trying to find the previous amount that experienced the increase, we divide by 1.5 to find the original amount because that amount*1.5 gives us 279.
Calling the original r, it is clear that 1.5r=279.
Solving for r, we find the original # of robberies to be 186.

Line JK passes through points J(-3, 11) and K(1, -3). What is the equation of line JK in standard form? The answers are
7x + 2y = -1
7x + 2y = 1
14x + 4y = -1
14x + 4y = 1
Linear equation is the equation of a straight line. A linear equation in standard form is: [tex]ax + by = c[/tex]
The equation of JK in standard form is: [tex]7x + 2y = 1[/tex]
Given that:
[tex](x_1,y_1) = (-3,11)[/tex] --- point J
[tex](x_2,y_2) = (1,-3)[/tex] --- point K
First, we calculate the slope (m) of JK using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, we have:
[tex]m = \frac{-3-11}{1--3}[/tex]
[tex]m = \frac{-14}{4}[/tex]
[tex]m = \frac{-7}{2}[/tex]
The equation is then calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
This gives:
[tex]y = \frac{-7}{2}(x - -3) + 11[/tex]
[tex]y = \frac{-7}{2}(x +3) + 11[/tex]
Multiply through by 2
[tex]2y = -7(x +3) + 22[/tex]
Open bracket
[tex]2y = -7x -21 + 22[/tex]
[tex]2y = -7x +1[/tex]
Rewrite in standard form as
[tex]7x + 2y = 1[/tex]
Hence, the equation of JK in standard form is:
[tex]7x + 2y = 1[/tex]

A) 12÷34=46
B) 12×34=38
C) 12+34=54
D) None of the above
The answer is B. One way you can tell what operation you are going to use is by the word. This has the word of, so that is one way to tell that an equation is multiplication. Also, this is 3/4 of 1/2, so you would multiply.
Answer:

Step-by-step explanation:
First you need to multiply 1/2 and 3/4 then subtract that answer to 1/2 and that is your answer so it is D
Jerry and his family will drive 1,022 miles from Houston to Indianapolis for their summer vacation. They plan to drive between 425 and 475 miles each day. At this rate, which is a reasonable number of days it will take Jerry's family to reach Indianapolis?
Answer:
The reasonable number of days to reach Indianapolis is 3 days.
Step-by-step explanation:
Total distance to be covered from Houston to Indianapolis, d= 1022 miles.
As they plan to drive between 425 and 475 miles/day, so the range of the rate of driving per day, r, is 425<r<475.
Let t day is the reasonable number of days to complete the journey.
As time = (distance)/(speed), so
[tex]t=\frac d r\cdots(i)[/tex]
The given range of the rate is
[tex]425<r<475[/tex]
If [tex]a>b[/tex], than [tex]1/a<1/b[/tex] for [tex]a,b\neq0[/tex];
[tex]\Rightarrow \frac {1}{425}>\frac {1}{r} >\frac{1}{475}[/tex]
If a>b, the for any [tex]\alpha>0[/tex], [tex]a\alpha>b\alpha[/tex], so multiply the above equation by [tex]d[/tex], we have
[tex]\frac {d}{425}>\frac {d}{r} >\frac{d}{475}[/tex]
[tex]\Rightarrow \frac {d}{425}>t >\frac{d}{475}[/tex] [from equation (i)]
[tex]\Rightarrow \frac {1022}{425}>t >\frac{1022}{475}[/tex] [given, d=1022 miles]
[tex]\Rightarrow \frac {1022}{425}>t >\frac{1022}{475}[/tex]
[tex]\Rightarrow 2.40>t >2.15[/tex]
So, to cover the distance of 1022 miles, with the speed in between 425 miles/day and 475 miles/day, Jerry's family will take in between 2.40 days and 2.15 days. This means, for the given speed range, they need 2 complete days and some fraction of 3rd day to reach Indianapolis.
Hence, the reasonable number of days to reach Indianapolis is 3 days.

The value of y varies directly with x. If x=104, then y=78. What is the value of x when y=39?
58
58
52
52
29.25
29.25
69.3
Answer: 52
Step-by-step explanation:
Since the value of y varies directly with x, y = kx where k is a constant.
Since x=104, then y=78, we need to calculate the constant k. This will be:
y = kx
78 = 104k
k = 78/104
k = 0.75
What is the value of x when y=39?
Since y = =kx
39 = 0.75x
x = 39/0.75
x = 52

The point, (-3, 2) is a solution to the following system.
y > x -2 x ≥ 1
True
OR
False
Answer:
False
Step-by-step explanation:
If you connect it, it won't make sense.
y>x - 2
Now plug it in
2 > -3 -2
2 > -5
That's true, but look at the next one
x >= 1
Plug it in
-3 >= 1
-3 isn't greater OR equal to 1, therefore it's false. I know for a fact, if one system isn't true for the point, then NONE of them are. It asked if the point was a solution to the whole system not just one. Trust me, it's false, whether you already "took the test" or not.
No responses yet... John is making trail mix based on a recipe that combines 6 cups of nuts with 5 cups of granola. John has 36 cups of nuts. How many cups of trail mix (total) does he have?
Given:
A recipe combines 6 cups of nuts with 5 cups of granola.
John has 36 cups of nuts.
To find:
Number of cups of trail mix (total) does he have.
Solution:
The recipe combines 6 cups of nuts with 5 cups of granola.
The recipe combines 1 cup of nuts with [tex]\dfrac{5}{6}[/tex] cups of granola.
The recipe combines 36 cup of nuts with [tex]36\times \dfrac{5}{6}[/tex] cups of granola.
So, the number of cups of granola in trail mix is
[tex]Granola=36\times \dfrac{5}{6}[/tex]
[tex]Granola=6\times 5[/tex]
[tex]Granola=30[/tex]
Total number of cups = cups of nuts + cups of granola.
