X= 30/5.6 or x≈5.36

To solve for x, you need to isolate it, meaning that it is by itself and not surrounded by any other numbers.

In this case, a number is right next to x meaning it’s meaning multiplied by it

In order to get rid of the 5.6, we have to divide both sides by 5.6. (This way 5.6/5.6 becomes one and therefore x is by itself).

So x= 30/5.6 or x≈ 5.36 :D

Write an algebraic expression to represent each statement<br> 50 added to half of a number, c

Fittoniya [83]

The expression represented by 50 added to half of a number, c is 50 + c/2

<h3>What are expressions?</h3>

Expressions are mathematical statements that are represented by variables, coefficients and operators

<h3>How to translate the algebraic expression?</h3>

The expression is given as

50 added to half of a number, c

half of a number, c means divide c by 2

So, we have

50 added to half of a number, c => 50 added to c/2

Added to means +

So, we have

50 added to half of a number, c => 50 + c/2

Hence, the expression represented by the statement is 50 + c/2

If exactly 180 people sign up for a charter flight, Leisure World Travel Agency charges $298/person. However, if more than 180 p

lesantik [10]

Answer:

The max. revenue is $57,121.

This happens with 239 passengers.

The price of the ticket is $239 per person.

Step-by-step explanation:

Let the variable "P" denote the number of passengers.

If P=180, then the ticket cost is $298/person. Then the price is reduced by $1 for each additional person.

In general, if P=(180+x), then the ticket cost becomes (298-x) per person.

The revenue can be defined as the ticket cost multplied by the number of passengers:

$R=P*T=(180+x)(298-x)=53,640-180x+298x-x^2\\\\R(x)=-x^2+118x+53,640$

We can derive R and equal to zero to maximize the function.

$dR/dx=-2x+118=0\\\\x=118/2=59$

The amount of passengers is:

$P=180+x=180+59=239$

The price of the tickets is

$T=298-59=239$

The revenue is:

$R(59)=(180+59)(298-59)=239*239\\\\R(59)=57,121$

Find the cost of 4.8 kilograms of potatoes at the price of $0.75 a<br> kilogram?

Gelneren [198K]

Answer: $3.60

Step-by-step explanation:

If you need 4.8 kilograms of potatoes and each kilograms costs $0.75, then we should multiply 0.75 by 4.8 to find the cost of 4.8 kilograms of potatoes.

4.8 x 0.75 = 3.6.

Therefore, the cost of 4.8 kilograms is $3.60 dollars. I hope this helps, and good luck!
