Since the news outlet posted a poll on its website, it would be biased on the fact that it's on the website. Some people don't read the website, or don't have a computer or internet.

Write an expression for the sequence of operations described below. Multiply u by t, subtract the result from v, then triple wha
Triss [41]

Answer:

The expression is 3(v - ut)

Step-by-step explanation:

* Lets explain how to solve the problem

- There are some words we can change them to mathematics symbols

# Add  ⇒ +

# Subtract ⇒ -

# Multiply ⇒ ×

# Divide ⇒ ÷

- Ex:

# Add x and 6 ⇒ x + 6

# Subtract 7 from y ⇒ y - 7

# Multiply 5 by m ⇒ 5 × m = 5m

# Divide n by 2 ⇒ n ÷ 2 = n/2

*<em> Lets solve the problem</em>

- We want to write an expression for the sequence of operations

  described below

- Multiply u by t, subtract the result from v, then triple what you have

* <em>Lets make these operations</em>

- Multiply u by t

∴ u × t = ut

- Subtract the result from v

- Means take ut from v, so v will come first

∵ The result is ut

∴ v - ut

- Triple what you have

∵ Triple means multiply by 3

∵ we have (v - ut)

∴ 3(v - ut)

* The expression is 3(v - ut)

There are x boys playing in the park. The number of girls playing in the park is equal to the square root of the number of boys.
konstantin123 [22]

Answer:

Option A. 36

Step-by-step explanation:

Let

x-------> the number of boys

y------> the number of girls

we know that

x+y=42 -----> equation A

y=\sqrt{x} -----> equation B

using a graphing tool to solve the system of equations

Remember that the solution is the intersection point both graphs

The solution is the point (36,6)

see the attached figure

therefore

The number of boys is 36

Discriminant of a quadratic equation can be calculated as:

Discriminant = b² - 4ac

b = coefficient of x term = 2
a = coefficient of squared term = 1
c = constant = 7

So,

Discriminant = 4 - 4(1)(7) = -24

So, the correct answer to this question is option C
