** 72/400 = 0.18**

**0.18 x 100 = 18**

**Add percentage. 18%!**

Question

Solve the system of equations
â€‹
2xâˆ’9y=14
x=âˆ’6y+7
â€‹
x, equals ?
y, equals ?

Solution 1

**Step-by-step explanation:**

Hey there!

Given eqautions are;

2x-9y= 14â€¦â€¦â€¦â€¦â€¦(i)

x= -6y+7â€¦â€¦â€¦â€¦â€¦â€¦(ii)

~ Putting the value of"x" from eqaution (ii) in eqaution (i).

2(-6y+7) - 9y = 14

~ Simplify it.

-12y +14 -9y= 14

21y = 0

y =0/21

**Therefore****,**** ****y=**** ****0****.**

Now,

~ Put value of "x" on eqaution (ii).

X = -6(0)+7

x= (0)+7

x= 7

**Therefore****,**** ****x****=**** ****7****.**

__Check____:____ __

*Putting** the** value** of** X** and** y** **in **eqaution** **(**ii)*

*7**=** **-**6**(**0**)**+**7*

**7****=****7****(True)****.**

**x****=**** ****7**

**y=**** ****0**

__Hope____ it____ helps____.____.____.____.__

Solution 2

**Answer:**

x = 7

y = 0

**Step-by-step explanation:**

use substitution method:

2(-6y + 7) - 9y = 14

-12y + 14 - 9y = 14

-21y = 0

y = 0

x = -6(0) + 7

x = 7

Question

Question

You have budgeted $4,800 for a company to complete guest satisfaction surveys for you. They charge $1,800 + $6 per respondent. How many respondents will you be able receive for the money paid?

Solution 1

There are 500 **respondents **will you be **able receive** for the money paid.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The **budgeted **for a **company **to complete guest satisfaction surveys for you is, $4,800.

And, They charge $1,800 + $6 per respondent.

Now,

Let Number of **respondents **will you be able receive for the money paid is, x

Hence, We can formulate;

â‡’ $1800 + $6x = $4800

â‡’ 1800 + 6x = 4800

â‡’ 6x = 4800 - 1800

â‡’ 6x = 3000

â‡’ x = 500

Thus, There are 500 **respondents **will you be **able receive** for the money paid.

Question

A stadium has 54,000 seats.Seats sell for 30$ in section A,$24 in section B, and $18 in section C.The number of seats in section A equals the total number of seats in section B and C.Suppose the stadium takes in $1,384,800 from each sold -out event.How many seats does each section hold

Solution 1

**Answer:**

46160

**Step-by-step explanation:**

Total price of seats A = 1384800Ã·2=692400

seats in section A=692400Ã·30=23080

seats in section B = 23080Ã·2=11520

seats in section C=23080Ã·2=11520

Totals seats in the stadium=23080 +11520 +11520 = 46160
