a girl scout has (5x-12) boxes of cookies and sells (3x+18) of them. Write an expression to represent the amount of boxes she has left. i need help.
Answers
Answer:
2x - 30
Step-by-step explanation:
You have to subtract 3x + 18 from 5x - 12:
=> 5x - 12 - ( 3x + 18) = 5x - 12 - 3x - 18 = 5x - 3x - 12 - 18 = 2x - 30
The first step was to apply distributive properties to get rid of the parenthesis, after that the terms were arranged and the like terms combined
Answer = 2x - 30
Simplified becomes 2x-30

Step-by-step explanation: Since the total number of games played in the graph is 12, if you half that and get six, you half the total number of wins as well and get 4. :]
Answer:
B. 4
Step-by-step explanation:
First we need to find out the total amount of games played. Since there are no variables, we can just simply add up the values under "number of games".
Doing so will get us 12. Now lets convert each out come into a fraction.
Wins - 8/12
Loses - 2/12
Ties - 2/12
Once we have them in fractions we need to convert them to decimals then to percents. To do so we just need to divide the numerator by the denominator.
8/12 = 0.66666666
2/12 = 0.16666666
2/12 = 0.16666666
Next multiply each decimal by 100 to get the percent.
0.66666666*100 = 66.666666%
0.16666666*100 = 16.666666%
0.16666666*100 = 16.666666%
Finally you need to take the total amount of games, and divide it by each percent to find the amount of games won, lost and tied

Find the surface area of a top open cylinder
12 in radius
2 in height
Answers
The surface area of the top open cylinder is 6810.149 sq.cm.
A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.
Surface area of a cylinder = Base area + Lateral area
Base area of a cylinder = 2 × π × r²
Lateral area of a cylinder = (2 × π × r) × h
Therefore, here base area of a cylinder = 2× π × 12²
= 5837.27 sq.cm.
And, lateral area of a cylinder = (2 × π × 12) × 2
= 972.8784 sq.cm.
Therefore, total surface area of a cylinder = 5837.27 + 972.8784
= 6810.149 sq.cm.

Brayden conducted a scientific experiment. For a certain time, the temperature of a compound rose 2 2/5 degrees in 1/5 of an hour. How much did the temperature of the compound rise in one hour?
Answers
Answer: 12 degrees or 11 5/5 or 60/5
Step-by-step explanation:
Since the temperature is rising 2 2/5 per 1/5 of an hour we just need to multiply 2 2/5 times 5 because 5/5 would equal the whole hour. In order to multiply easier you can change 2 2/5 to an improper fraction by multiplying the whole number with the denominator and then adding the numerator. Which you should get 12/5 next change 5 to a fraction which would be 5/1. 5 times 12 is 60 and 5 times 1 is 5. You get 60/5 which if divided is 12.
For the number line you just have to find 1/5 and 2 2/5 on it and mark it.

A.
52 inches
B.
7 inches
C.
42 inches
D.
49 inches
Answers
=========================================================
Explanation:
Let's say we have a triangle with sides x,y,z
Also, let's further say we know that x = 19 and y = 28 (from AB and BC respectively).
The third missing side z can't be nailed down to a single number, but we can establish a possible range. That range is
y-x < z < y+x
28-19 < z < 28+19
9 < z < 47
So any number between 9 and 47, excluding both endpoints, will work as a possible side length for the third missing side.
Something like 7 inches is too small, so we rule out choice B. Choice D is ruled out since 49 inches is too big. Same goes for choice A also.
The only thing left is choice C. The 42 is between 9 and 47
In other words, 9 < 42 < 47 is true.
So that's why the third missing side could be 42 inches.
Side note: I'm using a modification of the triangle inequality theorem.
