Answer: 85 student tickets, 65 adult tickets.
Let's say the # of students is x and the # of adults is y. The two equations we get are 7.50x + 15y = 1612.50 and x + y = 150
x = 150 - y
7.5(150-y) + 15y = 1612.5
1125-7.5y+15y=1612.5
7.5y=487.5
y=65

x=150-65
x=85

Hope this helps!

Jack is playing a game. When a player wins 3 consecutive games, the player receives 10 bonus points and then the player’s total
svlad2 [7]
Let Jack's current point is p

After winning 3 consecutive games, the bonus point is given by
b(p)=p+10

The score after 5% = 0.05 increase is
s(p)= (1+0.05)p=1.05p

(s.b)(p)=1.05(p+10)=1.05p+10.5

Paws at play made a total of $1,234 grooming 22 dogs. Paws at play charges $43 to groom each small dog and $75 for each large do
vovikov84 [41]

Step-by-step explanation:

We are asked to write a system of equations using our given information.

Let x be number of small dogs and y be number of large dogs.

We have been given that paws at play made a total of $1,234 grooming 22 dogs, which means that number of small dogs and large dogs is 22. We can represent this information as:

x+y=22...(1)  

We have been given that paws at play charges $43 to groom each small dog and $75 for each large dog. So the total grooming charges for grooming x small and y large dogs will be 43x+75y, that is equal to total charges for grooming $1234.

We can represent this information as:  

43x+75y=1234...(2)

Therefore, our desired system of equations is:

x+y=22...(1)

43x+75y=1234...(2)

To make 1 batch of green paint, Ethan mixes 2 3/8 (Fraction) just so you know
zzz [600]

Answer:

11\frac{7}{8} ounces

Step-by-step explanation:

Since Ethan needs 2 \frac{3}{8} ounces of blue paint to make 1 batch of green paint, we can multiply the amount of blue paint needed by 5 to see how much blue paint he'll need for 5 batches of green paint.

(2 \frac{3}{8})5 = 10 \frac{15}{8} \rightarrow \boxed{11\frac{7}{8}}

This means he will need 11\frac{7}{8} ounces of blue paint to make 5 batches of green paint.

What is the sum of the given polynomials in standard form? (x2 – 3x) (–2x2 5x – 3).
Rina8888 [55]

Sum of standard form polynomials means adding the terms of same variable. The sum of the given polynomial in standard form is,

-x^2+2x-3

<h3>What is polynomial equation?</h3>

A polynomial equation is the equation in which the unknown variable is one and the highest power of the unknown variable is n.

Here, <em>n</em> is any real number.

In the polynomial equation the the terms are added or subtracted from each other only when the power of the variable is same.

Given information-

The first polynomial equations given in the problem is,

(x^2 - 3x)

The second polynomial equations given in the problem is,

(-2x^2+ 5x - 3).

To find the sum of these two polynomials, add the two terms together as,

(x^2 - 3x)+(-2x^2+ 5x - 3)

Let the result of the sum is f(x). Thus,

f(x)=(x^2 - 3x)+(-2x^2+ 5x - 3)\\f(x)=x^2-3x-2x^2+5x-3

Separate the similar power variable as,

f(x)=(x^2-2x^2)+(-3x+5x)-3\\f(x)=-x^2+2x-3

Thus the sum of the given polynomial in standard form is,

-x^2+2x-3
