Answer: 72874
Step-by-step explanation:
To solve this, you can first find the sum of all numbers from 1 to 400. Using the formula for arithmetic series, you can get 1+2+3+4...+400=80200. Then, you can subtract all multiples of 11 from 1 to 400. That is 11+22+33+44+...+396. Dividing all numbers by 11, we have the new arithmetic series 1+2+3+4..+36, which using the formula, equals 666. Multiply this by 11 to get 7326 and subtract from 80200 to get 72874.

what is the answer for 5/11x + 2/3x - 1/6x = -189
Answer:
x = -198
Step-by-step explanation:
5/11 x + 2/3 x - 1/6 x = -189
66(5/11x + 2/3x - 1/6x) = 66(-189)
30x + 44x - 11x = -12474
63x = -12474
x = -198
Answer:
x = -210
Step-by-step explanation:
[tex]\frac{5}{11x} + \frac{2}{3x} - \frac{1}{6x} = -189[/tex]
[tex]\frac{37}{33x} - \frac{1}{6x} = -189[/tex]
[tex]\frac{21}{22x} = -189[/tex]
0.9x = -189
[tex]x = \frac{-189}{0.9}[/tex]
x = -210

Hi there! Please help me asap and explain how you did it... Tysm!♡♡
Answer:
A = ( -1 , 4 )
B = ( -4 , 3 )
C = ( -2 , 1 )
Explanation:
You basically just flip it along the line like a mirror would
A = ( -1 , 4 )
B = ( -4 , 3 )
C = ( -2, 1 )
Basically, you match the coordinates of the image to the other part and see the new coordinates. It's like seeing something in a mirror, but with a different view.

Sam’s Soups is open 6 days a week, 76 hours in all. Its hours are the same every day, except on Saturday and Sunday. On those days, it is open 2 hours longer. How long is Sam’s Soups open on Sunday? Use an equation to solve.
Answer:
14 hours
Step-by-step explanation:
Let x be the number of hours open on each of the four days (because it is six days per week) that are not Saturday or Sunday. Thus, the total number of hours on those days would be 4x. Then, we are told that Sam's Soups are open 2 hours longer on Saturdays and Sundays, so that would be x + 2. There are two of those days, so that would be 2(x + 2). Since all of these hours total 76, we have our equation:
4x + 2(x + 2) = 76
4x + 2x + 4 = 76
6x = 72
x = 12
Remember, 12 hours is the number of hours that Sam's Soups is open on days that are not Saturday and Sunday. Those days are x + 2. Thus, that is 12 + 2 = 14 hours.
Answer:
14 hours
Step-by-step explanation:
x = hours on day other than saturday and sunday
y = hours on Saturday and Sunday.
Sam's soups are only open 6 days a week, and 2 are weekends, so it is only open on 4 weekdays.
4x + 2y = 76
We know the hours on Saturday and Sunday are 2 hours more than the weekday hours.
So,
y = x + 2
Substituting that back into the original equation,
4x + 2(x+2) = 76
4x + 2x + 4 = 76
6x = 72
x = 12
y = 14
So Sam's Soups is open 14 hours on Sunday.

Answer:

12,455 + x = 23,894
x = 10,560
Step-by-step explanation:
Let's say that the variable 'x' represents the salaries for the second month, so out equation would be:
10,205 + x = 23,894
To solve, we must isolate the variable by subtracting 12,455 from both sides:
10,205 + x = 23,894
-10,205 -10,205
x = 10,560
So, the second month's salary was $10,560
Step-by-step explanation:
Answer: x = $30,560
Step-by-step explanation:
1. Let the second month payment be x
2. The first month + The second month = both of the months
3. So substituting: 10,205 + x = 40,765
4. Subtract 10,205 from both sides: x = 30,560

The amount of money you spend on x CDs and y DVDs is given by the equation 14x+18y=126. Find the intercepts.
Need this soon please
Answer:
The y intercept is (0,7) The x intercept is (9,0)
Step-by-step explanation:
You set the x to zero if you want the y intercept and vice versa for the x intercept.
14x+18y=126 y intercept
14(0)+18y=126
0+18y=126
18y=126 divide by 18
y=7
do the same thing for the x intercept except set the y to 0
Two stores advertise a discount on the same type of watch. At both stores, the original price of the watch was $35.00
Store A discounts the price of the watch by 20%
Store B discounts the price of the watch by 15%
How much less is the discounted price of the watch at store A than the discounted price of the watch at store B?
Store A has $ 1.75 less discounted price than Store B.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
The original price of the watch was $35.00
Store A:
Discount = 20%
So, price after discount = 35 - 35 x 0.20
= $28
and, Store B:
Discount = 15%
So, price after discount = 35 - 35 x 0.15
= $29.75
Hence, Store A has $ 1.75 less discounted price than Store B.

How do the expressions 2q^2-3p and 2(p+q)/q Compare when p=8 and q=4?
Answer with a symbol :)
Answer:
2q^2-3p > 2(p+q)/q
Step-by-step explanation:
You want to compare 2q^2-3p and 2(p+q)/q when (p, q) = (8, 4).
EvaluationTo find the value of the expression, put the numbers in place of the corresponding variables, and do the arithmetic.
2q^2 -3p
2(4)^2 -3(8) = 2(16) -3(8) = 32 -24 = 8

What is 5,890,000 in Scientific Notation?
Answer:
5.89 x 10^6
The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.
Calculating scientific notation for a positive integer is simple, as it always follows this notation:
a x 10b
Follow the steps below to see how 5,890,000 is written in scientific notation.
To find a, take the number and move a decimal place to the right one position.
Original Number: 5,890,000
New Number: 5.890000
count how many times you moved the decimal and that's your power
in this case it's ^6
The average weight of five cats is 5.2 kg. The weights of four of the cats are 5.4 kg, 5 kg, 4.8 kg, and 4.9 kg. Find the weight of the fifth cat.
Answer:
5.9 kg
Step-by-step explanation:
Remember! To find the average of things, you add them al up and divide by how many things there are. This is an important detail that will help us solve the problem
It says the average is 5.2
This means ...
( weight of cat 1 + cat 2 + cat 3 + cat 4 + cat 5 ) ÷ 5 = 5.2
Let's plug in all of the values we know to find the weight of cat 5
( 5.4 + 5 + 4.8 + 4.9 + CAT 5 ) ÷ 5 = 5.2
Let's add all of this up and solve this!
( 20.1 + CAT 5 ) ÷ 5 = 5.2
multiply 5 by both sides so we can get the weight of cat 5 alone
20.1 + CAT 5 = 26
subtract
CAT 5 = 26 - 20.1
CAT 5 = 5.9
the weight of cat 5 is 5.9 kg
