Answer:
10
Step-by-step explanation:
one possible way to do this is to simply observe that 12*2 =24, so 5 shares must also be multiplied by 2
another way is to set up a proportion, 5/12=x/24, cross multiply, 5*24=12x, solve for x, x=(5*24)/12=10
solve 2m + 4m - 3m squared
George is making brown paint he wants to make brown paint he must mix purple and yellow paint together in a 1:1 ratio. In order to make purple he must mix red and blue paint together at a ratio of 2 quarts red to 1 quart of blue. How many quarts of yellow does he need
Answer:
3/4 quarts of yellow paint is needed
Step-by-step explanation:
From the question, we are told that:
In order to make purple he must mix red and blue paint together at a ratio of 2 quarts red to 1 quart of blue.
3 quart of Purple paint mix requires 2quarts of red paint and 1 quart of blue paint.
We are also told that:
When George wants to make brown paint he must mix purple and yellow paint together in a 1:1 ratio.
This means 1 Purple paint to 1 Yellow paint
4/4 quarts of Yellow paint = 1 yellow paint
3/4 quarts of Yellow paint = 3/4 quarts of purple paint

A drivers distance varies directly as the amount of time traveled. After 6 hours, a driver had traveled 390 miles. How far had the driver traveled after 4 hours?
The distance traveled after 4 hours is 260 miles.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 - 9 = 9 is an equation.
We have,
Distance ∝ Time
Distance = K x Time
Now,
390 = 6K
K = 390/6
K = 65
Now,
Distance = 65 x 4
Distance = 260 miles
Thus,
After 4 hours the distance traveled is 260 miles.

Sheila is going to the arcade with only 15 dollars to spend. The cost of each game is 75 cents and the price of admission into the arcade is 5 dollars. Which inequality can be used to solve for g, the number of games that she can play, and what is the maximum number of games she can play?
A - 5g + 0.75 <_ 15, 13 games
B - 0.75g + 5 <_ 15, 14 games
C - 0.75g + 5 <_ 15, 13 games
D - 5g + 0.75 <_ 15, 14 games
Answer:
C
Step-by-step explanation:
It is 75 cents a game plus 5 dollars admission. You should automatically subtract 5 dollars for admissions. That would give you ten dollars. You would just multiply how many games by how much they cost.
(You can also find the number of games first, and then solve the two inequalities that match that number backwards)

11. During an evening out, Dean paid a cab driver $20. He
then spent $25 on dinner and half of his remaining money on a painting. He bought an umbrella for $23.75 and had $42.15 left. How much money did Dean have at the beginning of the weekend?
Answer:
$176.80
Step-by-step explanation:
$42.12 (what he had left) + 23.75 = 65.90
65.90 (Amount he had after he bought the painting) + 65.90 (The other half of his remaining money he spent on the painting) = 131.80
131.80 + 25 + 20 = 176.80

14)
Answer: (10) 3.2 (11) option 2 (12) option 4
(13) Distributive (14) Associative
Step-by-step explanation:
10) "Absolute value" makes the number positive.
- |-4| + |-7.2|
= - 4 + 7.2
= 3.2
11) "Opposite" changes the sign.
the opposite of [tex]-\sqrt{\dfrac{2}{5}}[/tex] is [tex]+\sqrt{\dfrac{2}{5}}[/tex]
12) Reciprocal means "flip" the fraction
the reciprocal of [tex]-\sqrt{\dfrac{2}{5}}[/tex] is [tex]-\sqrt{\dfrac{5}{2}}[/tex]
13) a(b + c) = ab + ac is the Distributive Property
[tex]-\sqrt5(2+X)[/tex]
= [tex]-\sqrt5(2) -\sqrt5(X)[/tex]
= [tex]-2\sqrt5 -X\sqrt5[/tex]
14) a · (b · c) = (a · b) · c is the Associative Property
[tex]20(4\sqrt5)[/tex]
= [tex](20\cdot 4)\sqrt5[/tex]
Solve for x:
30 = 14 - 4(3 - x)
Answer:
-7
Step-by-step explanation:
First, distribute. 30 = 14 - 12 - 4x
Then, simplify and get the regular numbers one the left side.
30 = 2 - 4x 28 = -4x
Finally, divide both sides by -4 to get x by itself.

Item 19 Question 1 A nurse is making identical first aid bags for patients using 72 antiseptic wipes, 55 adhesive bandages, and 36 packets of ointment. What is the greatest number of identical first aid bags the nurse can make with the least amount of items leftover? Describe the contents of each bag.
Answer:
36 identical bags with 2 antiseptic wipes, 1 adhesive bandage and 1 ointment in each bag.
Leftovers: 19 adhesive bandages.
Step-by-step explanation:
First of all, let us try to find out the maximum number of identical first aid bags that can be prepared from the given contents.
The maximum number of bags that can be prepared will be equal to the quantity of the content which is available in minimum amount.
And that is number of packets of ointments.
Therefore, greatest number of bags that can be prepared is 36.
Now, it can be seen that 72 antiseptic wipes are available.
72 is a multiple of 36.
Therefore, if we put 2 antiseptic wipes in each bag, no leftovers will be there for packet of ointments and antiseptic wipes.
Now, let us consider adhesive bandages.
Maximum of 1 adhesive bandages can be put in each bag because only 55 such bandages are available.
Therefore, the answer is:
36 identical bags with 2 antiseptic wipes, 1 adhesive bandage and 1 ointment in each bag.
Leftovers: 19 adhesive bandages.

determine if the given equations are functions or not function
x = 3, y² = -5x -12, x² + y² =81. are all not functions. the others are functions.
Step-by-step explanation:

A function assigns the values. The correct options are C and E.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
An equation is said to be a function if for each different value of x(input) it should give a different output. Therefore, for different inputs of x, the value of the output y should be different and unique. Also, the values if the equation produces the same output for two values of x it also said to be a function.
A.)
x = 3, since for every value of x the value is 3, which is not possible. Hence, this is not a function.
B.)
x² + y² = 81
For the given equation if the value of x is given as 0, the value of y will be,
x² + y² = 81
0² + y² = 81
y² = 81
y = ±√81
y = -9, 9
Hence, this can not be a function.
C.) y = -x + 11
For the given equation if the value of x is kept anything the value of y will be different. Thus, this is a function.
D.)
y² = -5x - 12
For the given equation if the value of x is given as less than -2.4, there will be two values of y. Thus, the given equation is not a function.
E.)
y = 2x² - 6x + 4
The given function will return will the same value of y for 2 different values of x. Hence, this is a function.
F.)
y = -7
Since the given equation can only have the value of y as 7. Therefore, it is not a function.
Hence, the equations that are a function are y = -x + 11 and y = 2x² - 6x + 4.

What is the property of 42x1=42
Help please I have a F and I’m confused..?
Answer:
x = -4
Step-by-step explanation:
x-5 = -9
Add 5 to each side
x-5+5 = -9+5
x = -4
Answer:
A. x = -4
Step-by-step explanation:
x - 5 = -9 (plus 5 on each side to get rid on 5 on the left side) so -9 + 5
x = -4
-6x + 3x = -21 linear equations
well combine like terms

Step-by-step explanation:
-6x + 3x = -21
Combine like terms
-3x = -21

Which of the following are true about the graph of f(x)=−4x2?
Select the TWO that apply.
the answer is A and D
when you differentiate the question you find that the maximum point is (0,0)i.e
[tex] \frac{dy}{dx} = - 8x[/tex]
when dy/dx is 0 values of x are 0,0
and the function shows that valies of x are real numbers.
The domain of the graph is (−∞,∞), {x|x∈R} and the maximum point (0,0) which is the correct answer would be options (A) and (D)
What are the domain and range of the function?The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.
Given function as
f(x) = -4x²
The range is the set of values that correspond with the domain.
Range: (−∞,0], {y|y≤0}
Domain: (−∞,∞), {x|x∈R}
and the function shows that values of x are real numbers.
The maximum point is when differentiating the function, which is (0,0) i.e
dy/dx = -8x
Values of x are 0 when dy/dx is 0.
Hence, the domain of the graph is (−∞,∞), {x|x∈R} and the maximum point (0,0) which is the correct answer would be options (A) and (D)
