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

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.

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

x is always +3 ahead (30-27=3)
and y is always trailing behind x by -3
Answer:
y = x - 3
Step-by-step explanation:
You are given an x and a y and need to find the difference.
Set up a formula using one of the given x and y pairs and solve.
y = x - u plug in an x and y and solve for the unknown(u)
27 = 30 - u
-3 = -u
u = 3
Now plug the unknown into the original equation
y = x - 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

Can somebody solve this: x^4+2x^3-25x^2-26x+120
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)
