Answer:
12
Step-by-step explanation:
to find how much she made off of brownies, use this equation
15×.8=$12
then, to find how much she made off of cupcakes, subtract the amount she made off of brownies from the total price
$30 - $12 = $18
lastly, to find how many cupcakes could be bought with $18, divide 1.5 from 18
18 ÷ 1.5 = 12
so 13 cupcakea

if the mean of 4,6,4,7,(x+1),8 and 2 is 5 ,find the median
===========================================================
Explanation:
The mean is found by adding up all of the values and dividing by n, where n is the number of values in the set.
In this case, we have n = 7 values here. We count (x+1) as well since x is a placeholder for a number, which makes (x+1) also a placeholder in a sense.
As for what replaces x, we're not sure yet but we can use algebra to solve.
Lets add up all of the values given except for the "5" at the end. That 5 is the mean which is not part of the data set.
Adding up those values mentioned gives:
4+6+4+7+(x+1)+8+2 = x+32
Then divide this over n = 7 to get the mean 5
(x+32)/n = mean
(x+32)/7 = 5
-----------------------------
Let's isolate x
(x+32)/7 = 5
x+32 = 7*5
x+32 = 35
x = 35-32
x = 3
If x = 3, then x+1 = 3+1 = 4
So the (x+1) is being a placeholder for the number 4.
In other words, we'll replace the (x+1) with 4.
The data set of
4,6,4,7,(x+1),8,2
updates to
4,6,4,7,4,8,2
-----------------------------
We'll get to the median in a moment, but first we need to check if we have the correct replacement for (x+1)
Add up the values in the set {4,6,4,7,4,8,2}
Doing so leads to: 4+6+4+7+4+8+2 = 35
Then divide by n = 7 to compute the mean: 35/n = 35/7 = 5
We get the mean is 5 which matches with the instructions. So we have the correct replacement for the (x+1). We can now find the median.
------------------------------
To find the median of any data set, we need to make sure the numbers are in order from smallest to largest.
Right now {4,6,4,7,4,8,2} is not sorted, but we can sort the items to get {2,4,4,4,6,7,8}
The median is at the exact middle. In this set, the median is that third copy of '4'. Note how "2,4,4" is to the left of the median while "6,7,8" is to the right of the median. There is the same number of values on either side of the median to show things are balanced and we are at the center point.
As an alternative, you can cross off each pair of outer values one at a time until you steadily arrive at the midpoint, which again is that third copy of '4'.
So that's why the median is 4.

HELP
Answer:
x < 4
Step-by-step explanation:
Given the inequality :
- 20 > - 4(2x - 3)
Open the bracket
-20 > - 8x + 12
Collect like terms
-20 - 12 > - 8x
-32 > - 8x
Divide both sides by - 8
4 > x
x < 4

Simplify the following equation. Explain each step and write the property used. 3x+2x-3+10=27
Answer:
x=4
Step-by-step explanation:
1. Add like terms: 5x+7=27
2. Use the subtraction property on both sides to get rid of 7: 5x=20
3. Divide 5 on both sides to get x by itself: x=4
A colony of 1,000 bacteria doubles in size every 18 minutes. What will the population be 54 minutes from now? (show steps) - will give brainliest
Answer:
3000.24
Step-by-step explanation:
We know that every 18 min, the colony grows 1000, so to make it easy, the way i do it is that i find out how much it grows per min
1000 / 18 = 55.56
Then, to find out how big it will be in 54 min, we just multiply
55.56 x 54 = 3000.24
So that will be the size of the colony in 54 min. I hope this helps :)

What is the image of the point (9,7) after a rotation of 180 counterclockwise about the origin
The image of the point (9,7) after a rotation of 180 counterclockwise about the origin is at (-9, -7)
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.
Rotation of a point A(x, y) 180 counterclockwise about the origin produces an image at A'(-x, -y).
Hence, the image of the point (9,7) after a rotation of 180 counterclockwise about the origin is at (-9, -7)

What is the Inequality for this graph?
Given:
The graph of an inequality.
To find:
The inequality for the given graph.
Solution:
From the given graph it is clear that the boundary line passes through the points (6,0) and (0,-4). So, the equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-0=\dfrac{-4-0}{0-6}(x-6)[/tex]
[tex]y=\dfrac{-4}{-6}(x-6)[/tex]
[tex]y=\dfrac{2}{3}(x-6)[/tex]
[tex]y=\dfrac{2}{3}x-4[/tex]
The area under the boundary line is shaded and boundary line is a dotted line it means the points on the line are not included in the solution set. So, the inequality sing must be <.
[tex]y<\dfrac{2}{3}x-4[/tex]
Therefore, the required inequality for the given graph is [tex]y<\dfrac{2}{3}x-4[/tex].
