Answer:
y = 2x - 12 or A
Step-by-step explanation:
6x - 3y = 36 Subtract 6x from both sides.
-3y = 36 - 6x Divide by - 3
-3y/-3 = 36/-3 - 6x/-3
y = -12 + 2x
The answer is A
What is the length of segment BD?
Mallory and Aimee save money for summer camp. They both plan to save the same amount of money. Mallory has 35$ and plans to save 15$ each week. Aimee has 5$ and plans to save 50$ a week. How many weeks it'll take for Aimee and Malloy to have the same amount of money
Answer:
0.857 weeks
Step-by-step explanation:
Using the information provided we can create the following equations for the total amount Mallory (M) and Aimee (A) will save after x number of weeks...
M = 35 + 15x
A = 5 + 50x
Now we would need to make both of these equations equal one another and solve for x to calculate after how many week both Aimee and Mallory will have saved the same amount of money
35 + 15x = 5 + 50x ... subtract 5 and 15x from both sides
30 = 35x ... divide both sides by 35
[tex]\frac{30}{35}[/tex] or 0.857 = x
Finally, we can see that after 0.857 weeks both Mallory and Aimee will have saved the same amount of money.
*** The process provided is correct but I believe that the actual values for Aimees savings should be $50 and plans to save $5 a week, this would make the final result 1.5 weeks which would make more sense***
What is the height of the flagpole in the diagram below
Answer: The height of the flagpole is 12 feet.
Step-by-step explanation:
Let the height of the flagpole be 'H'.
So, from the figure, we can conclude that, the height and shadow of the flagpole is in proportion to the height and shadow of the stick.
Given:
Height of stick is,
Shadow of the stick is,
Shadow of the flagpole is,
Now, as these are in proportion, we have
Plug in the given values and solve for 'H'. This gives,
Hence, the height of the flagpole is 12 feet.

Its actually pretty hard, so I don't really want to show my explanations with words, but there is a number explanation. Sorry if this is wrong. It is pretty hard, since you asked lots of times, I tried to give it a go.
6 X 10^-5 is 2*10^3 times the value of 3 X 10^-8.
6 X 10^-5 is how many times the value of 3 X 10^-8 is to be determined.
Fraction is defined as the number of compositions that constitute the whole.
Let 6 X 10^-5 is x times the value of 3 X 10^-8.
[tex]6 * 10^{-5}= x 3 * 10^{-8}\\\\x = \frac{6 * 10^{-5}}{3 * 10^{-8}} \\\\x = 2 *10^3[/tex]
Thus, 6 X 10^-5 is 2*10^3 times the value of 3 X 10^-8.

Answer:
x < 6
Step-by-step explanation:
Distribute the 2 to the parentheses:
2(x − 3) < 6

Solve for x:
2x < 12
x < 6
So, x < 6 is the answer.

The equation of line h is y = -2x + 1. If line h is dilated with a scale factor of 4 with respect to the origin, what is the equation of the new line?
Answer:
y = -2x + 4Step-by-step explanation:
Given line h:
y = -2x + 1Dilated line is parallel to original, so will have same slope of -2
y-intercept will change by a scale factor of 4:
(0, 1) → (0*4, 1*4) = (0, 4)So the equation of the new line is:
y = -2x + 4Which of the following is a true statement of two linear equations?

Which number sentence is true?
A. -1/12 times 6/7 = -1/14
b. -1/12 times (-6/7)= -1/14
c. 1/12 times 6/7 = -1/14
d.1/12 times (-6/7) = 1/14
Answer:
We conclude that:
[tex]-\frac{1}{12}\cdot \frac{6}{7}=-\frac{1}{14}[/tex]
Hence, option (A) is true.
Step-by-step explanation:
Let us solve the expression
-1/12 times 6/7 = -1/14Let us solve the L.H.S to check whether it becomes equal to R.H.S
[tex]-\frac{1}{12}\:\times \frac{6}{7}[/tex]
Factor the number: 12=6×2
[tex]-\frac{1}{6\cdot \:2}\cdot \frac{6}{7}[/tex]
Cross - cancel the common factor

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}[/tex]
[tex]-\frac{1\cdot \:1}{2\cdot \:7}[/tex]
Multiply the number: 7×2 = 14
[tex]-\frac{1}{14}[/tex]
Therefore, we conclude that:

In the first week of June, a restaurant sold 10,345 omelets. In the second week, 1,096 fewer omelets were sold than in the first week. In the third week, 2 thousand more omelets were sold than in the first week. In the fourth week, 2 thousand fewer omelets were sold than in the first week. How many omelets were sold in all in June? *
Answer:
40, 284 omelets
Step-by-step explanation:
Given that:
In the first week of June = 10345 omelets were sold
In the second week = 1096 fewer omelets are sold than in week one
i.e. 10345 - 1096 = 9249 omelets
In the third week = 2000 more were sold than week one.
i.e. 2000 + 10345 = 12345 omelets
In the fourth week = 2000 fewer omelets were sold than week one.
i.e. 10345 - 2000 = 8345 omelets
Thus, the total quantity of Omelet sold in the month of June is:
= (10345 + 9249 + 12345 + 8345) omelets
= 40, 284 omelets
Marie has 11 coins, all of which are quarters and nickels. In all, they're worth $1.15. How many of each kind of coin does Marie have?
Answer:
Step-by-step explanation:
x + y = 11
.25x + .05y = 1.15
25x + 5y = 115
-25x - 25y = -275
-20y = -160
y = 8 nickels
x + 8= 11
x = 3 quarters
3 quarters and 8 nickels

Find the particular solution to y ' = 2sin(x) given the general solution is y = C - 2cos(x) and the initial condition y of pi over 3 equals 1 . (5 points)
-2cos(x)
closeIncorrect
3 - 2cos(x)
checkCorrect
2 - 2cos(x)
-1 - 2cos(x)
Answer:
[tex]y=2-2\cos(x)[/tex]
Step-by-step explanation:
We have the differential:
[tex]y^\prime=2\sin(x)[/tex]
With the general solution:
[tex]y=C-2\cos(x)[/tex]
And we want to find the particular solution such that it satisfies the initial condition:
[tex]\displaystyle y\Big(\frac{\pi}{3}\Big)=1[/tex]
So, we have:
[tex]y=C-2\cos(x)[/tex]
Substituting π/3 for x and 1 for y yields:
[tex]\displaystyle 1=C-2\cos\Big( \frac{\pi}{3} \Big)[/tex]
Solve for C. Evaluate:
[tex]\displaystyle 1=C-2(\frac{1}{2})[/tex]
Simplify:
[tex]1=C-1[/tex]
Hence:
[tex]C=2[/tex]
Therefore, our particular solution will be:
[tex]y=2-2\cos(x)[/tex]
Hence, our answer is C

A bowl contains blueberries and strawberries. There are a total of 16 berries in the bowl. The ratio of blueberries to strawberries is 3 : 1. How many of each berry are in the bowl?
Answer:
12 blueberries and 4 strawberries
Step-by-step explanation:
We can try the guess method.
3:1 3 + 1 = 4 4 is too low. We need a sum of 16.
Multiply both numbers in the ratio by 2.
6:2 6 + 2 = 8 8 is still too low
Multiply both numbers in the ratio by 4.
12:4 12 + 4 = 16 16 is correct.
Answer: 12 blueberries and 4 strawberries
how do you solve 4devided by
12
Answer:
0.33333333
Step-by-step explanation:
4 divided by 12 would be written like this: 4/12
it's always good to simplify if possible, so it should look like this: 1/3
3 which is the denominator would be divided by 10, so 3/10 = 0.33333333
0.33333333 is the answer because the numerator is how many times you multiply it, and 1*0.33333333 = 0.33333333
