Answer:
-24x + 18y
Step-by-step explanation:
6 x -4x = -24x
6 x 3y = 18y
The simplified expression is -24 x + 18y.
What is Distributive Property?The distributive property states that multiplying the sum of two or more addends by a number yields the same outcome as multiplying each addend separately by the number and combining the resulting products.
Given:
6(-4x + 3y).
Now, using Distributive Property
a x (b+ c)= a x b+ a x c
So, 6(-4x + 3y).
= 6 x (-4x) + 6 x 3y
= -24 x + 18y
Hence, the simplified expression is -24 x + 18y.

the answer I guess is 8.
Micah is planning a road trip. He estimates that he will drive a total of of 8 1/4 hours. He wants to stop for gas after 1/3 of the total time has passed. How long will he drive before he stops for gas? Express your answer as a mixed number.
a. 8 1/12 hours
b. 2/3 hours
c. 11/4 hours
d. 2 3/4 hours
8.25 hours is our base number here. 1/3 of it is taken up when he stops at the gas station.
8.25, 4.125 is half of it, 2.75 is our answer for this,
8.25/3 gives you 2.75 due to 2.75 making it 5.5 when doubled and so on
so, the answer is 2 3/4 hours, D

Norah has 2 3 ton of stone to spread equally in 4 square yards. How many tons of stone will be spread in each square yard
Answer:
The answer is 1/6.
Step-by-step explanation:
The question is worded in such a way to be open to misunderstanding. I feel it could mean Norah must spread her stone at the rate of 2/3 of a ton per square yard across 4 square yards and the total is sought.
It could also be saying that Norah has 2/3 of a ton to be divided equally across 4 square yards and is seeking the amount of stone each square yard needs.
In the former case it is a matter of multiplying the vulgar fraction by four and in the latter case the answer could be approached by considering the total amount of stone given is four times the answer that is required and so would be given by dividing 2/3 by 4/1 or more simply by multiplying by 1/4 and not forgetting to cancel the resulting fraction down to the lowest common denominator.
A better way for practical purposes would be to convert 2/3 of a ton into pounds and then divide by four. A workman required to do the work would not be messing around with fractions but would be working in pounds and tons or if using Imperial measure it would be pounds, stones, hundredweight and tons.

In a sample of 800 adults, 242 said that they liked sugar cereals. Three adults are selected at random without replacement. Find the probability that all three like sugar cereals.
Answer:
[tex]P(A) = 0.0274[/tex]
Step-by-step explanation:
Given
[tex]n = 800[/tex] --- Population
[tex]A = 242[/tex] --- those that liked sugar cereals
Required
Probability that three selected like sugar cereals
The probability that the first adult selected likes sugar cereals is:
[tex]P(A_1) = \frac{242}{800}[/tex]
The probability that the second adult selected likes sugar cereals is:
[tex]P(A_2) = \frac{242-1}{800-1} = \frac{241}{799}[/tex]
We subtracted 1 because it is a probability without replacement
Similarly:
[tex]P(A_3) = \frac{241-1}{799-1} = \frac{240}{798}[/tex]
The required probability is calculated as follows:
[tex]P(A) = P(A_1) * P(A_2) * P(A_3)[/tex]
[tex]P(A) = \frac{242}{800} * \frac{241}{799} * \frac{240}{798}[/tex]
[tex]P(A) = \frac{242*241*240}{800*799*798}[/tex]
[tex]P(A) = \frac{13997280}{510081600}[/tex]
[tex]P(A) = 0.0274[/tex]

The direct proportion y=kx is given in the following table. Find the coefficient k, and fill in the table:
Answer:
Look at image
Step-by-step explanation:
image shown below, copy the answer from there.
The value of coefficient k is 5. The required values are y = 15.5 when x = 3.1, y = 12.5 when x = 2.5, y = 6 when x = 1.2, y = 4.5 when x = 0.9, x = 0.06 when y = 0.3, and x = 0.02 when y = 0.1.
What is the equation?The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.
The direct proportion y = kx is given in the shown table.
Find the coefficient k, and fill in the table:
As per the question, we have
y = kx .....(i)
To determine the value of k, we substitute the value of x = 0.14 and y = 0.7 in equation (i),
⇒ 0.7 = k (0.14)
⇒ k = 0.7/0.14
⇒ k = 5
Substitute the value of k = 5 in equation (i), and we get
y = 5x .....(ii)
Now, we are finding the values of the table,
Substitute the value of x = 3.1 in equation (ii), and we get
y = 5(3.1)
y = 15.5
Similarly, the other required values are
y = 12.5 when x = 2.5, y = 6 when x = 1.2, y = 4.5 when x = 0.9, x = 0.06 when y = 0.3, and x = 0.02 when y = 0.1.

Do the parenthesis first.....
52 - 43 = 9
9 ÷ 3x ( 2 + 3)
Parenthesis ( do the distributive property...multiply 3x by whatever is inside the parenthesis)
9 ÷ 3x × 2 + 3x × 3
9 ÷ 6x + 9x
Combine like terms (both x's)
9 ÷ 15x

Answer:
x = 4, y = 116
Step-by-step explanation:
In a parallelogram, the opposite sides and opposite angles are congruent.
3x + 4 = 16 ( subtract 4 from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
and
y - 60 = 56 ( add 60 to both sides )
y = 116

A cubic root function has a domain of x>=7 and a range of y>=-1, what is the domain of its inverse?
Answer:
The domain of the inverse is x >= -1
Step-by-step explanation:
Functions:
Domain: Values of input(usually x).
Range: Values of output(usually y)
Inverse function:
The domain of the inverse function is the range of the original function.
The range of the inverse function is the domain of the original function.
In this question:
Original function has range y >= -1.
So the domain of the inverse is x >= -1
20% of Aussies have blue eyes. If 4 Aussies in a play group have blue eyes, how many Aussies are in the group?
Answer:
20
Step-by-step explanation:
Step 1: 4 = 20% × Y
Step 2: 4 = 20/100 × Y
Multiplying both sides by 100 and dividing both sides of the equation by 20 we will arrive at:
Step 3: Y = 4 × 100/20
Step 4:Y = 4 × 100 ÷ 20
Step 5: Y = 20
The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
20% = 4
100% = 20
The total number of people in the group is 100 people.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
We have,
Number of Aussies with blue eyes = 4
Percentage of blue eyes in the Aussies = 20%
This can be written as:
20% = 4
Now,
The percentage of the total number of people in the group = 100%
So,
20% = 4
Multiplying 5 on both sides.
5 x 20% = 5 x 4
100% = 20
This means,
The total number of people in the group is 100.
Thus,
The total number of people in the group is 100 people.
