What is the solution to the following system
Answer:
Option C. (4, -1, 3)
Step-by-step explanation:
The given system of equations is
x + y + z = 6 -----(1)
x - y + z = 8 ------(2)
x + y - z = 0 -----(3)
We subtract equation 1 by 3
(x + y + z) - (x + y - z) = 6 - 0
z + z = 6
2z = 6
z = 3
Now we subtract equation 1 by 2
(x + y + z) - (x - y + z) = 6 - 8
2y = -2
y = -1
Now we put the values of x and y in equation 1
x + (-1) + 3 = 6
x + 2 = 6
x = 6 - 2 = 4
Therefore, the solution of the equations is (4, -1, 3).
Option C is the answer.
What is the percent of change from 180 to 387
To find the percent of change, subtract to find the amount of change
387 - 207 = 180. The increase is 207.
Then divide the amount of change by the original amount
207 ÷ 180 = 1.15
Change the decimal to a percent, and multiply the number by 100:
1.15 X 100 = 115
The answer is 115%

A pharmacist is filling small empty bottles with cough syrup from a larger bottle. He can solve the inequality to find the number of small bottles, x, that can be filled from the larger bottle and still have 250 milliliters left in the larger bottle. Which statement describes the number of small bottles the pharmacist can fill?
The number of small bottles the pharmacist can fill from the larger bottle and still have 250 milliliters remaining can be discovered through a mathematical operation, presumed to be a subtraction-based inequality. This would determine that the amount in the larger bottle, minus the total amount in the small bottles, is equal to or greater than 250 ml.
Explanation:Unfortunately, the question lacks an inequality to be solved. However, we can assume that the problem may involve a mathematical operation including subtraction, since the pharmacist wants to keep a certain amount of milliliters (250 ml) left in the bigger bottle. In that case, the amount of syrup in the larger bottle minus the total amount of syrup placed into the small bottles should be equal to 250 ml.
Conceptually, this can be understood as follows:
If 'a' is the total quantity in the larger bottle, 'x' is the quantity which each smaller bottle can contain, and 'n' is the number of smaller bottles, we can create an inequality as follows: a - nx >= 250. This inequality means that the pharmacist can fill 'n' number of smaller bottles and still be left with at least 250 ml in the larger bottle.
So, solving this formula would yield the number of bottles that can be filled without reducing the larger bottle's quantity below 250 ml.

The pharmacist can fill any number of small bottles x that satisfies the inequality: [tex]\[ x \leq \left\lfloor \frac{L - 250}{S} \right\rfloor \][/tex]
The correct statement describing the number of small bottles the pharmacist can fill is that the pharmacist can fill x small bottles, where x is any integer less than or equal to the quotient of the volume of the larger bottle minus 250 milliliters, divided by the volume of one small bottle.
To solve this problem, let's denote the volume of the larger bottle as L milliliters and the volume of each small bottle as S milliliters.
The pharmacist wants to fill x small bottles and have 250 milliliters remaining in the larger bottle.
Since the pharmacist can fill the small bottles until there is no more volume left to fill an additional bottle, the inequality that represents this situation is:
[tex]\[ xS \leq L - 250 \][/tex]
To find the maximum number of small bottles that can be filled, we divide both sides of the inequality by S
[tex]\[ x \leq \frac{L - 250}{S} \][/tex]
In summary, the pharmacist can fill any number of small bottles x that satisfies the inequality:
[tex]\[ x \leq \left\lfloor \frac{L - 250}{S} \right\rfloor \][/tex]
-3.3=x/6 solve for x
-3.3=[tex]\frac{x}{6}[/tex]

Shaun has a set of blocks. When he separates the blocks into groups of 21, he has 34 groups of blocks. How many groups of blocks would Shaun have if he separated them into groups of 14 instead?
So if I had this problem I would multiply 21 x 34= 714 then I would divide it by 14 which would get me 51. There would be 51 blocks in each group!
Shaun would have 51 groups of blocks if he separated them into groups of 14. We found this by calculating the total number of blocks Shaun originally had (714) and dividing by the new group size (14).
Explanation:The problem is about finding the total number of blocks Shaun has. We first multiply the number of groups Shaun can make (34) by the size of each group (21), which gives us 714 blocks. Then, we find out how many groups he'd have if he separated the blocks into groups of 14 instead, by dividing the total number of blocks (714) by the new group size (14). So, Shaun would have 51 groups of blocks if he divided them into groups of 14.

the sunflower is the only single flower that grows as high as 3 meters. it can grow 30 cm each week. in which week does the sunflower reach a height of 3 meters ?
To determine when a sunflower reaches a height of 3 meters, given it grows at a rate of 30 cm per week, we divide 300 cm by 30 cm per week to find that the sunflower will reach the height in the 10th week.
The question asks us to determine in which week a sunflower, which can grow 30 cm each week, reaches a height of 3 meters.
Calculation of Weeks Required for Sunflower to Reach 3 Meters:
Firstly, we need to convert the final desired height from meters to centimeters, since the growth rate is given in centimeters per week:
3 meters = 300 centimeters
Next, we divide the final desired height by the weekly growth rate to find the number of weeks:
300 cm / 30 cm/week = 10 weeks
Therefore, the sunflower reaches a height of 3 meters in the 10th week.
if (5)=-3, then the point ???? is on the graph of f
f(x) = y
f(5) = -3 therefore the point is (5, -3).
Which is the graph of y = 1/x?
answer: the first graph
explanation:
it would not be the second one because it is a slope (y = mx + b) and so would be the third choice.
i don't think it would be the last one because it's going only up to 40. which the equation say only y = 1/x and it's not a big number equation.

Write the expression in standard form. three divided by quantity three minus twelve i.
3/(3 - 12i)
To simplify this, multiply both sides by (3 + 12i)
(3 - 12i)(3 + 12i)
Distributive property.
3(3 + 12i) - 12i(3 + 12i)
9 + 36i - 36i - 144i^2
Simplify.
9 - 144i^2
i^2 can be interpreted as -1.
9 + 144
Combine like terms.
153 is the simplified version of the bottom half of the expression.
Now for the top half.
3(3 + 12i)
Distributive property.
9 + 36i
We can simplify this further by factoring.
3(3 + 12i)/153
1 + 4i/17
1/17 + 4i/17 is the simplified version of the expression. (This is your answer.)
Let me know if you have any other questions.
To write the expression in standard form, divide 3 by the quantity 3 - 12i and rationalize the denominator by multiplying by the conjugate of the denominator to simplify to (3 + 12i)/51.
To write the expression in standard form, 3 divided by (3 - 12i), you need to rationalize the denominator by multiplying both the numerator and denominator by the conjugate of the denominator to eliminate the imaginary part. The conjugate of 3 - 12i is 3 + 12i.
Therefore, multiplying by the conjugate gives you: (3/(3 - 12i)) x ((3 + 12i)/(3 + 12i)).
This simplifies to the standard form: (3(3 + 12i))/(3^2 - (12i)^2) = (3(3 + 12i))/(9 + 144) = (3 + 12i)/51.

We are drawing a single card from a standard 52 card deck. Find the following probability
The probability of drawing a single card from a standard 52-card deck is calculated using the formula 'Desired outcomes/Total outcomes'. For a specific card, the probability is 1/52. For a face card, it's 12/52 or simplified to 3/13.
Explanation:In the context of your question about drawing a single card from a standard 52 card deck, it's important to first understand the composition of the deck. A standard deck comprises of 52 cards; four suits of 13 cards each. The suits are clubs, diamonds, hearts, and spades, with clubs and spades being black, while diamonds and hearts are red.
To calculate the probability of drawing a specific card, we need to use the formula for probability, which is Desired outcomes/Total outcomes. In your case, drawing a specified single card from a 52-card deck, there is only one desired outcome and the total number of outcomes is 52. Hence, the probability would be 1/52.
If you are looking for the probability of drawing, say a face card (jack, queen, king), remember the deck has 12 face cards. Hence, the probability becomes 12/52 = 3/13.

What value should going to the empty boxes to complete the calculation for finding the product of 0.98×0.73? both numbersare the same however only input the answer at one time and your answer.
Answer:
Missing same value is 0.02
Step-by-step explanation:
Instead of multiplying big decimal numbers we put short cut by making 0.98 as a difference of near integer and one decimal.
i.e 0.98 =1-0.02
Since 0.02 is the same for other also other term
0.73 = 0.75-0.02
Now product can be done very easily.
Steps are shown below:
0.98x0.73
= (1-0.02) (0.75-0.02)
= 0.75 -0.02(1+0.75)+0.0004
= 0.7504-(0.035)
= 0.7154

find the exact value of cos 5pi/3
Answer:
1/2
Step-by-step explanation:
The angle 5pi/3 shows up in the 3rd quadrant and is equivalent to the angle 300 degrees. The "reference angle" of 300 degrees is 60 degrees; the reference angle in this case has the same trig function values as does 300 degrees. Thus, the cosine of 5pi/3 is the same as the cosine of 60 degrees, which is 1/2.
Using equivalent angles, it is found that:
[tex]\cos{\left(\frac{5\pi}{3}\right)} = \frac{1}{2}[/tex]
[tex]\frac{5\pi}{3}[/tex] is an angle in the fourth quadrant, as [tex]\frac{2\pi}{3} \leq \frac{5\pi}{3} \leq 2\pi[/tex].
To find the equivalent in the first quadrant to an angle in the fourth quadrant, we subtract [tex]2\pi[/tex] from the angle, then:
[tex]2\pi - \frac{5\pi}{3} = \frac{6\pi}{3} - \frac{5\pi}{3} = \frac{\pi}{3}[/tex]
Just as in the first quadrant, the cosine is positive in the fourth quadrant, thus, applying the equivalent angle:
[tex]\cos{\left(\frac{5\pi}{3}\right)} = \cos{\left(\frac{\pi}{3}\right)} = \frac{1}{2}[/tex]
