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?

Answers

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

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

Answers

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)

What’s the solution for y=2x+7 y=3x-1

Answers

Answer:

x=8 and y=23

Step-by-step explanation:

Rewrite equations:

y=2x+7;y=3x−1

Step: Solve y=2x+7 for y:

y=2x+7

Step: Substitute 2x+7 for y in y=3x−1:

y=3x−1

2x+7=3x−1

2x+7+−3x=3x−1+−3x(Add -3x to both sides)

−x+7=−1

−x+7+−7=−1+−7(Add -7 to both sides)

−x=−8−x−1=−8−1

(Divide both sides by -1)

x=8

Step: Substitute 8 for x in y=2x+7:

y=2x+7

y=(2)(8)+7

y=23(Simplify both sides of the equation)

and y is always trailing behind x by -3

Answer:

y = x - 3

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
