Use the elimination method to solve the following system of equations:
2x+y=3
3x – y= 12
The solution is
x = 3
y = -3
(3, -3)
Step-by-step explanation:
Choose one of the equations and isolate y. I will use the first one.
2x + y = 3
Y = 3 - 2x
Now sub the solution for y into the equation below.
3x - y = 3
3x - (3 - 2x) = 12
3x - 3 + 2x = 12
5x - 3 = 12
5x = 15
x = 3
To get y, sub the answer for x into one of the equations.
2(3) + y = 3
6 + y = 3
y = 3 - 6
y = -3
Answer:
(x,)y) =(3,-3)
Step-by-step explanation:
add the equations vertically to eliminate one variable
2x +y = 3
3x -y = 12
5x =15 divide both sides by 5
x = 3 now substitute the given value of x into the equation 2x+y=3
2 x 3 + y = 3 multiply 2x3
6 +y =3 move constant to the right
y = 3-6
y = -3

click on the measurements that is equal to 20 cups.
Measurement of 5 quarts is equal to 20 cups.
What are Measurements?Measurement is the method of comparing the properties of a quantity or object using a standard quantity.
Measurement is essential to determine the quantity of any object.
We have the measurement, 1 cup = 1/4 quarts
Let x be the number of quarts for 20 cups.
By using proportion,
1 / (1/4) = 20 / x
Cross multiplying,
x = 20 × (1/4)
x = 5
Hence the measurement of 20 cups is equal to 5 quarts.

Thee measurement equals to 20 cups is 5 quarts.
Thus, option (a) is correct.
To determine which measurement is equal to 20 cups, compare the conversion factors between cups and each of the given measurements.
As, the conversion factors are:
1 quart is equal to 4 cups 1 pint is equal to 2 cups 1 gallon is equal to 16 cups 1 fluid ounce is equal to 0.125 cups1. 5 quarts
= 5 x 4 cups/quart
= 20 cups
2. 40 pints
= 40 x 2 cups/pint
= 80 cups
3. 1 gallon
= 1 x 16 cups/gallon
= 16 cups
4. 320 fluid ounces
= 320 x 0.125 cups/fluid ounce

what is the mean of the set of numbers please explain case I don't get it
A 5 feet
B 5 feet 1 inch
C 5 feet 2 inches
D 5 feet 3 inches
E 5 feet 4 inches
F 5 feet 5 inches
Answer:
Add up all of the numbers in the set and then divide by how many numbers there are.
Step-by-step explanation:
I'm not sure if that's the most conventional way- but it's how I learned.
Here's your set of numbers:
4'11, 5'0, 5'0, 5'1, 5'2, 5'2, 5'3, 5'4, 5'4, 5'4, 5'4, 5'4, 5'5, 5'5, 5'6
And here's that same set of numbers in inches (which is what I'd use to find it out):
59, 60, 60, 61, 62, 62, 63, 64, 64, 64, 64, 64, 65, 65, 66
Which adds up to a total number of 15 numbers in the set.
Add up 59, 60, 60, 61, 62, 62, 63, 64, 64, 64, 64, 64, 65, 65, 66.
That's 943.
Then we divide 943 by how many numbers there are in the set (15).
The mean of your set is 62.8666667.
Round to the nearest whole number, making it 63.
How many feet is 63 inches?
5'3 is your answer. I hope this helped you and I hope it was correct!

A 10% increase followed by another 10% increase is not the same as a total increase of
20%.
What is the total percentage increase?
Answer:
21%
Step-by-step explanation:
Another 10% increased means it becomes 110*110/100 = 121. The first 10% increase means the second 10% increase will be an actual 11% increase from the original, so it will be a total of 21%.
Answer:
21%Step-by-step explanation:
Because the first 10% increase is calculated as 10% of what you started with. The second 10% is 10% of what you started with plus 10% of the increase caused by the original 10% increase.
Let's do the maths…
Let's start with 100 to make things easy.
We know that 10% of 100 is 10.
We know that 20% of 100 is 20.
So if we increase 100 by 10% we get 110.
If we increase 100 by 20% we get 120.
Now lets do the 10% plus 10%.
From the first 10% increase we were left with 110.
Now if we take 10% of the 110 we have 11.
Add that to the 110 and we get 121.
This is why people are surprised how quick a lone can rise if we don't pay it off. We are paying interest on the basic sum plus interest on the interest, then interest on the interest on the interest.

Step-by-step explanation:
The profit p gained from selling an item can be modeled by a quadratic function in terms of its cost c. If the cost of the item is at $100 or $400, there will be no profit or loss. But if the cost is $250, the item generates the maximum profit of $30.
Answer:
Uh I'm not really sure how to screenshot on my laptop, but the answer should be B.
Step-by-step explanation:
Lets say I made a graph, P being profit C being cost.
P
50|___|___|___|___|___|
40|___|___|___|___|___|
30|___|___|___|___|___|
20|___|___|___|___|___|
10 |___|___|___|___|___|C
0___100|200|300|400|500
It goes from 100 (LOW) to 400 (HIGH). 250 being the the cost of the item, and the maximum profit being 30. Cost 250,0__Profit 0,30. In all 250,30.
Therefore whatever the letter answer is they might be shuffled, do the one that most compares to this formula.

Write the phrase as an expression. 20 less than the product of −2.5 and a number x
Answer:
-2.5x-20
Step-by-step explanation:
-2.5x-20
Answer:
-2.5x - 20
Step-by-step explanation:
"20 less than..." means that you are subtracting 20 from something else, and that something else is usually the next thing in the phrase. it's tricky because it's first in the phrase, but in the expression, it will come last, or after the next operation (which, in this case, is "the product of -2.5 and a number x). the key is to pay attention to the wording. "the product of -2.5 and a number x" is something that can stand alone, but "20 less than" depends on something else, so that's generally how you can tell that it's going to be written after something else, if that makes sense.
"...the product of -2.5 and a number x" means that you are multiplying -2.5 and x. "a number x" just means that x is a variable and its numeric value is currently unknown.
so, as an expression, this would be -2.5x - 20. i hope this helps and i hope my explanation made sense lol! have a lovely rest of your day <3

Answer:
The answer is 22.5 lbs or 22 and a half lbs of mashed potatoes.
Step-by-step explanation:
The ratio of potatoes is 1.5.
10 lbs potatoes * 1.5 = 15 lbs mashed
So 15 lbs potatoes * 1.5 is: 22.5 lbs mashed potatoes.

A teacher offers gift cards as a reward for classroom participation. The teacher places the gift cards from four different stores into a bag and mixes them well. A student gets to select two gift cards at random (one at a time and without replacement). Each outcome in the sample space for the random selection of two gift cards is equally likely. What is the probability of each outcome in the sample space?
1/16
1/6
1/4
1/2
Answer:
its either 1/4 or 1/16. i havent done this in forever.. so i cant figure out which one it is. go with your gut feeling, but i think its 1/4
Answer:
The answer is D. 1/2
Step-by-step explanation:
Because the probability of getting each gift card is 1/4. So since the student picks it without replacement, this means that we're multiplying 1/4 X 1/3 which would equal 1/12. Now we multiply 1/12 by 6 because there are six different variations of getting the cards. This would give us 6/12 or 1/2.

Amico
OOOO
6
Answer:
6 lines of symmetry
Step-by-step explanation:
This is a 6 sided polygon which is known as hexagon.
Now, line of symmetry of this hexagon is a line that passes through the centre of it and thereby divides it into equal parts.
Now, we can see the short lines on each side of the hexagon. When they are extended to join a similar line on the opposite face, they all pass through the centre.
Thus, there are
