Di are you alright? I noticed the fact that you aren't online from 7th April or so-
(-5/6x+51/2)-(2/3x+4)
Answer:
-1.5x + 21.5 (or (43-3x)/2)
Step-by-step explanation:
(-5/6x + 51/2) - (2/3x + 4)
First, find the opposite of 2/3x + 4 because of the negative sign.
-5/6x + 51/2 - 4/6x - 4
Now combine -5/6x and -4/6x to get -9/6x or -3/2x
-3/2x + 51/2 - 4
Convert 4 into 8/2 since 51/2 is a fraction.
-3/2x + 51/2 - 8/2
Since the denominators of 51/2 and -8/2 are the same, just subtract 51 and 8 to get 43.
-3/2x + 43/2
-3/2x and 43/2 have the same denominator (2), so you can just put it like this (It's up to you!):
(43-3x)/2
The answer to (-5/6 + 51/2) - (2/3x + 4) is -3/2x + 43/2 (or (43-3x)/2)
Or you could put it like this (I converted both -3/2 and 43/2 to a decimal.)
-1.5x + 21.5
To celebrate getting a new job, Marco went out for a dinner that cost $100. If the localsales tax is 6% and Marco left a 15% tip on $100, what was the total cost of his meal?
Answer:
$121
Step-by-step explanation:
So if the meal cost $100, finding out the percentages is pretty easy.
The sales tax is 6%, and 6% of 100 is simply 6.
15% of 100 is simply 15.
So, adding the total cost of the meal plus the sales tax plus the tip is simply $121.

You put $900 into an account earning 2% interest compounded continuously. Find the amount in the account at the end of 12 years.
Given:
Principal value = $900
Rate of interest = 2% compounded continuously.
Time = 12 years.
To find:
The amount in the account at the end of 12 years.
Solution:
If the interest compounded continuously, then the formula for amount :
[tex]A=Pe^{rt}[/tex]
Where, P is principal, r is rate of interest, t is numbers of years.
Putting P=900, r=0.02 and t=12, we get
[tex]A=900e^{0.02(12)}[/tex]
[tex]A=900e^{0.24}[/tex]
[tex]A=1144.12423529[/tex]
[tex]A\approx 1144.12[/tex]
Therefore, the amount in the account at the end of 12 years is about $1144.12.

Mr. Mastrogiacomo is testing the hypothesis that the proportion of households in a large town that have high-speed internet service is equal to 0.7 against the alternative that the proportion is different from 0.7. What is the chief advantage of using a confidence interval to test this hypothesis rather than a significance test
Step-by-step explanation:
You can use a confidence interval (CI) for hypothesis testing. In the typical case, if the CI for an effect does not span 0 then you can reject the null hypothesis. But a CI can be used for more, whereas reporting whether it has been passed is the limit of the usefulness of a test.

7 freinds to a party if each freind will get 5 cookies and each box has 12 cookies how many boxes does shenika need to get
Answer:
3 boxes
Step-by-step explanation:
To find the answer for the problem consider the amount of friends and how many cookies they will receive
First multiply 5 and 7 to find the amount of cookies she needs
5 x 7 = 35
She needs 35 cookies but there are 12 cookies per box
36 / 12 is 3
We are using 36 because it is the closest number to 35 that 12 can go into
She needs to get 3 boxes in order for each friend to get 5 cookies
Hope I helped :]
Answer:
Shenika needs to get 3 boxes.
Step-by-step explanation:
7 friends x 5 cookies each = 35 cookies needed.
12 cookies in each box.
12 x 3 = 36 cookies.

You had $22 to on four raffle tickets . After buying them you had $6. How much did each raffle ticket cost?
Answer:
X=4
Each raffle ticket cost 4 dollars
Step-by-step explanation:
22-4x=6
solve
-4x=-16
Divide
x=4
Answer: 4 bucks
Step-by-step explanation: 22 bucks at first
You buy four tickets, then you have 6 bucks
If the amount spent is x, then 22 - 4x = 6, so -4x + 22 =6
22 minus 22 is 0, cancel it out — 6 minus 22 is -16
-4 divided by -4 is 0, now you only have x. -16/-4 = 4
X = 4, 4 bucks per raffle ticket

Answer:
Two walls are 6*2
Multiply, add the products, round UP and multiply times 6.
NOTE: Why round up? because if you need, for example, 1.22 gallons, you have to get 2 gallons. If you buy just 1 you'll be short, and you can't buy 0.22 of a gallon.

Find the slope of the line that contains the points named.
K(c + d, c-d), L(c-d, c+ d)
A.0
B.-1
C 1
Answer:
B. - 1Step-by-step explanation:
The slope of the line passing through two given points: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
K(c + d, c-d) ⇒ x₁ = c + d, y₁ = c - d
L(c-d, c+ d) ⇒ x₂ = c - d, y₂ = c + d
So, the slope:
[tex]m=\dfrac{c+d-(c-d)}{c-d-(c+d)}=\dfrac{c+d-c+d}{c-d-c-d}=\dfrac{2d}{-2d}=-1[/tex]

Arjun solved the equation 7·=56. His work is shown.
What error did Arjun make?
Math item stem image
CLEAR CHECK
56·7 is not equal to 392.
Arjun should have divided both sides of the equation by 56 instead of multiplying by 7.
Arjun should have divided both sides of the equation by 7 instead of multiplying.
