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

Gareth believes that if he flips a coin 820 times, it will land heads up exactly 410 times. What would you tell Gareth about his prediction?
Answer:
What I would tell Gareth is that his prediction is somewhat right because there is a 50/50 chance of landing the coin on each side because 410 is half of 820.

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.

Task 10: It takes 10 pounds of potatoes to make 15 pounds of mashed potatoes. At this rate:
How many pounds of mashed potatoes can they make with 15 pounds of potatoes?
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.

The admission ticket for Pat Pat Zoo is $1.50 for children and $4.00 for adults. On a certain day, 2200 people went to the zoo and $5050 was collected. How many children and how many adults went to the zoo that day?
Answer:
1380 children and 820 adults went to the zoo that day
Step-by-step explanation:
System of Equations
Define the following variables
x = number of children that went to the zoo
y = number of adults that went to the zoo
On a certain day, 2000 people went to the zoo, thus:
x + y = 2000
Solving for x:
x = 2000 - y [1]
The admission ticket is $1.50 for children and $4.00 for adults and that same day, $5050 was collected, then:
1.50x + 4y = 5050 [2]
Substituting x from [1]:
1.50(2000 - y) + 4y = 5050
Operating:
3000 - 1.50y + 4y = 5050
3000 + 2.5y = 5050
Subtracting 3000
2.5y = 5050 - 3000 = 2050
Dividing by 2.5
y = 820
From [1]
x = 2200 - 820 = 1380
1380 children and 820 adults went to the zoo that day

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.

Answer:
(x + 5) • (x + 3) • (x - 2) • (x - 4)
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 1 • 15 = 15
Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is 8 .
-15 + -1 = -16
-5 + -3 = -8
-3 + -5 = -8
-1 + -15 = -16
1 + 15 = 16
3 + 5 = 8 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 3 and 5
x2 + 3x + 5x + 15
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x+3)
Add up the last 2 terms, pulling out common factors :
5 • (x+3)
Step-5 : Add up the four terms of step 4 :
(x+5) • (x+3)
Which is the desired factorization
(x + 5) • (x + 3) • (x - 2) • (x - 4)
