Sylvia buys a case of water that contains 24 bottles and sells x number of bottles to her co-workers. Sam buys a case of water than contains 36 bottles and sells three times as many bottles as Sylvia sold to his co-workers. How many bottles of water did Sylvia sell if they ended up with the same number of bottles of water left over?
It is given that Sylvia sells x number of bottles and Sam sells three times as many bottles as Sylvia sold to his co-workers.
So, number of bottles Sam sold is 3x.
It is also given that, number of remaining bottle Sylvia and Sam have same.
So,
24 - x = 36 - 3x
3x - x = 36 - 24
2x = 12
x = 6
Therefore, Sylvia sells 6 bottles.
Hence, this is the required solution.

a On January 1, Rose's bank balance was $200. During the month, she wrote checks for $115.25 and $350.00 and made one deposit of $150.50. Which best represents her checking account balance at the end of the month?
Answer:
LOL she has a negative balance of "-114.75"
Step-by-step explanation:
to solve, all you need to do is "200-115.25-350+150.5"
we subtract the 2 values since she wrote the checks for someone to cash, which would empty from her bank, and then she made a deposit of 150.50, so we add that value.

Morgan missed 24 questions on her multiple choice math final that had a total of 200 problems. What percentage of questions did Morgan answer correctly?
Answer:
88%
Step-by-step explanation:
You start out by finding the number of questions she got correct
200 - 24 = 176 questions answered correctly
You then want to divide the number of question she answered correctly by the total number of questions there are.
176/200 or 176 ÷ 200 = 0.88
0.88 = 88/100 = 88%

Answer:

The slope of the line is 3 and the intercept on the y-axis is 7.
Step-by-step explanation:
The slope-intercept form of the equation of a line is y=mx+c, where "m" is the slope of the line and "c" is the intercept of the line on the y-axis.
To find the slope and intercept of 6x+2y=14, you should solve for "y".
From the equation we get;
2y=-6x=14 or dividing each side by 2, we'll get y=3x+7.
Answer:
Domain: (−∞,∞), {x|x∈R}
Range: (−∞,∞), {y|y∈R}
Which set represents a Pythagorean triple?

Answer:
Step-by-step explanation:
B
The set that represents a Pythagorean triple is B: 33, 44, 55
What is a Pythagorean triple ?A Pythagorean triple consists of three positive integers such that the square of the larger one of them is equal to the sum of the squares of the other two .
Let (a, b, c) represents a Pythagorean triple where a, b, c are positive integer and a is the larger one then a² = b² + c²
For A: 27 ,38, 42
Let a = 42 , b= 38 ,c= 27
⇒a² = 42² = 1764
and b² + c² = 38² + 27² = 1444 + 729 = 2173
∴a² ≠ b² + c²
Thus , A: 27 ,38, 42 is not a Pythagorean triple
For B: 33 ,44, 55
Let a = 55 , b= 33 ,c= 44
⇒a² = 55² = 3025
and b² + c² = 33² + 44² = 1089 + 1936 = 3025
∴a² = b² + c²
Thus , B: 33 ,44, 55 is a Pythagorean triple
For C: 35 ,38, 42
Let a = 42 , b= 35 , c= 38
⇒a² = 42² = 1764
and b² + c² = 35² + 38² = 1225 + 1444 = 2669
∴a² ≠ b² + c²
Thus , C: 35 ,38, 42 is not a Pythagorean triple
For D: 68 ,72, 81
Let a = 81 , b= 68 , c= 72
⇒a² = 81² = 6561
and b² + c² = 68² + 72² = 4624 + 5184 = 9808
∴a² ≠ b² + c²
Thus , D: 68 ,72, 81 is not a Pythagorean triple
Therefore, Only set B: 33, 44, 55 represents a Pythagorean triple.

Joseph and his family were going to the beach. Joseph's sister was running late so Joseph left their house with his mom. Joseph's dad waited for his sister to get ready and left one hour later driving 75 km/hour in an effort to catch up to Joseph and mom. After
driving for four hours Joseph's dad finally caught up. How fast was Joseph's mom driving?
Select the correct response:
100 km/hour
30 km/hour
60 km/hour
50 km/hour
Answer:
60 km/hr.
Step-by-step explanation:
When Dad caught up the the time he had been driving was 4 hours and the time Mom had been driving was 1 + 4 = 5 hours.
They both drove the same distance, d km.
For Dad:
speed = d / time
75 = d / 4
d = 75 * 4 = 300 km.
Mom took 5 hours to travel this distance, so
Mom's speed was 300 / 5 = 60 km/hr.
Step-by-step explanation:
Answer:

solve for x: |3x+12|= 18
=====================================================
Work Shown:
|3x+12| = 18
3x+12 = 18 or 3x+12 = -18
3x = 18-12 or 3x = -18-12
3x = 6 or 3x = -30
x = 6/3 or x = -30/3
x = 2 or x = -10
The rule used in step 2 is the idea that if |x| = k, for some positive number k, then x = k or x = -k. One equation breaks into two separate ones. From there we solve each equation for x as normal. Follow PEMDAS in reverse, undoing each operation, to isolate x.
If you're curious why the absolute value breaks into two parts, consider something like |x| = 7. This means x is 7 units away from zero on a number line. There are two possible locations where x could be: 7 and -7. This is one example showing why we get two different results. The same applies to our equation as well, just it's a bit more complicated.

su edad y la de su padre es igual a 36. ¿Qué edad tiene Ezequiel?
Usando un sistema de ecuáciones, hay que Ezequiel tiene 11 años.
¿Qué es un sistema de ecuaciones?Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.
En este problema, las variables son:
x: La edad de Sandro.y: La edad de Ezequiel.z: La idad de su padre.Sandro y Ezequiel son hermanos y el producto de sus edades es igual a la edad de su padre, o sea:
xy = z
Sandro es 8 años menor que Ezequiel, o sea:
x = y - 8.
La suma de su edad y la de su padre es igual a 36, o sea:
x + z = 36.
z = 36 - x
z = 44 - y
En el primer ecuácion:
xy = z
(y - 8)y = 44 - y
y² - 7y - 44 = 0
(y - 11)(y + 4) = 0
y - 11 = 0 -> y = 11.

6. Moe and Curly went to Best Buy. Moe bought four CDs and five DVDs and
paid $123. Curly bought two CDs and four DVDs and paid $84. What is the
cost of one CD? What is the cost of one DVD?
(Can y’all help me out real quick please)
How do I write my two equations for this??
Answer: one CD cost $12 and one DVD cost $15 .
Step-by-step explanation:
In this situation we will represent the cost o one CD by x and the number of one DVD by y. Four CDs plus five DVDs cost 123 so we will represent it by the equation 4x + 5y = 123
The same or the second part of the statement. 2 CDs plus 4 DVDs cost $84 so we will also represent that by the equation , 2x + 4y = 84
Since we have two equations we will use it to solve or x and y using the elimination method.
4x + 5y = 123
2x + 4y = 84 Multiply the down equation by -2 to eliminate the x variable.
-2(2x + 4y ) = -2(84)
-4x -8y = -168
We will now have the new equations ,
4x + 5y = 123
-4x - 8y = -168 Add both equations to
-3y = -45
y= 15
This means each DVD cost $15 .
Now we will now have to solve for x by plotting in the value of y into the equation .
4x + 5(15) = 123
4x + 75 = 123
-75 -75
4x = 48
x = 12
This also means that one CD cost $12.
Is 5 x 3^{x} equal to 15x?
Here's your answer, folks:
Without substitution, yes, here? No.
The value of the substituted numbers is essential to finding the correct answer in algebra.
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
5 x 3 = 15
15 squared or cubed = 15 x 15 || 15 x 15 x 15

In that case, 15 times a number could not possibly be equal to 5 x 3 unless x was actually 1, which we do not know.

NO

Answer:
15
Step-by-step explanation:
4x15=60
60-30=30
2x15=30
Answer:
Option C is the correct answer.
Step-by-step explanation:
We have been given that a and b are parallel to each with a straight angle.
If a and a are parallel, then angle suspended by a and b will be equal to each other. It is because of Alternate angle of triangle.
Let's head to the question.
According to the above statement, we have the following equation.
2x°= 4x -30°
0r, 2x° - 4° = -30°
0r, -2x° = -30
0r, 2x° = 30°
0r, x = 30°/2°
0r, x = 15°
Hence, x = 15° will show that lines a and b are parallel.
