Expression consists of numbers, variables, and mathematical operations. The expression f(w)=5(w+4) is equal to f(9)=5(9)+20.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The expression is given to you is,

$f(w)= 5(w+4)$

Now, if we solve the expression it can be written as,

$f(w)=5w+20$

substituting the value of w, we will get,

$f(9)=5(9)+20$

Hence, the expression f(w)=5(w+4) is equal to f(9)=5(9)+20.

koban [17]

Answer:

$11.32

Step-by-step explanation:

Greeting Cards = $1.5 x 2 = $3

Wrapping Paper = $2.29 x 3 = $6.87

Ribbon = $1.45 x 1 = $1.45

So now we must add the totals to figure out how much money Barbra spent in total.

$3 + $6.87 + $1.45 = $11.32

A football team plays in a large stadium. With a ticket price of $19, the average attendance at recent games has been 50 comma

tino4ka555 [31]

Answer:

Part 1: N(x) = 50,000 - 300(x-19)

Part 2: R(x) =-300x² + 55700x

Step-by-step explanation:

Given,

The original price of each ticket = $ 19,

The original attendance = 50,000

Part 1 :

∵ For the each $1 increase in the ticket price, attendance decreases by 300.

Let x represents the price of each ticket after increment,

Thus, if price increment = (x-19) dollars,

New attendance, N(x) = 50,000 - 300(x-19)

Part 2 :

Since, revenue = price of each ticket × attendance

Thus, the revenue from the football game,

R(x) = x(50,000 - 300(x-19))

R(x) = 50000x - 300x²+ 5700x

⇒ R(x) =-300x² + 55700x

Find the whole using the percent proportion.

MAVERICK [17]

Answer:390

Step-by-step explanation:

130% of a=507

130/100 x a=507

13/10 x a=507

13a/10=507

Cross multiplying we get

13a=507x10

13a=5070

Divide both sides by 13

13a ➗ 13=5070 ➗ 13

a=390
