Answer:

Step-by-step explanation:

9x+5y=35

Step 1: Add -5y to both sides.

9x+5y+−5y=35+−5y

9x=−5y+35

Step 2: Divide both sides by 9.

9x9=−5y+359

x=−59y+359

Answer:

x=−59y+359

Let's solve for x.

2x+5y=0

Step 1: Add -5y to both sides.

2x+5y+−5y=0+−5y

2x=−5y

Step 2: Divide both sides by 2.

2x2=−5y2

x=−52y

Answer:

x=−52y

Answer: c = [tex]\frac{24}{5}[/tex]

Step-by-step explanation:

Hey there!

Step 1: Cancel 33 on both sides.

24 - 2c = 2c + c

Step 2: Simplify 2c + c to 3c.

24 - 2c = 3c

Step 3: Add 2c to both sides.

24 = 3c + 2c

Step 4: Simplify 3c + 2c to 5c.

24 = 5c

Step 5: Divide both sides by 5

[tex]\frac{24}{5}[/tex] = c

Step 6: Switch Sides.

c = [tex]\frac{24}5}[/tex]

Can  √ 49 be simplified ?

Yes!   The prime factorization of  49   is

√ 49   =  √ 7•7   =

The total number of students will be 1952.

Based on the information, let the total number of students be x.

Therefore, the equation to solve the question will be:

3/4x = 1464

0.75x = 1464

x = 1464/0.75

x = 1952

In conclusion, the correct option is 1952.

Answer:

I'd say, ask google for help

Step-by-step explanation:

Say, "Hey Google"

I'll break this into four parts, one for each table.

Part 1

To see if we have a direct variation, we divide each y value over its corresponding paired x value. So we compute y/x. If we get the same result for each column, then we have a direct variation.

Column 1 = y/x = 2/20 = 0.025

Column 2 = y/x = 4/30 = 0.1333 approximately

We don't get the same y/x value, so we don't have a direct variation.

===============================================

Part 2

Same idea as before

Column 1 = y/x = 30/2 = 15

Column 2 = y/x = 90/6 = 15

Column 3 = y/x = 105/7 = 15

Column 4 = y/x = 165/11 = 15

We get the same result each time, so the constant of proportionality is k = y/x = 15.

Therefore the direct variation equation is y = 15x.

All direct variation equations are in the form y = kx.

===============================================

Part 3

Column 1 = y/x = 54/3 = 18

Column 2 = y/x = 90/5 = 18

Column 3 = y/x = 126/7 = 18

Column 4 = y/x = 162/9 = 18

We get the equation y = 18x, which is a direct variation

===============================================

Part 4

Column 1 = y/x = 15/1 = 15

Column 1 = y/x = 30/4 = 15/2 = 7.5

We get different values, so table 4 is not a direct variation.

Answer: The answer is 668.00

Step-by-step explanation: Part one (8 x 2.00)= 16.00 x 41.00 = 656.00 ⇒ ( 8 people, 2.00 per shoes, 41.00 total 656.00)

Part two 1.50 x 8 = 12.00 ( 8 people and 8 sodas for 1,50)

Part three 656.00 + 12.00 = 668.00 ( total price because of the shoes, the two games, the soda and the number of people that had to pay.)

HOPEFULLY THIS HELPS!!!

The expression for the total amount is;

⇒ $16.00 + $32,800 + $12.00 = $32,828

What is an expression?

Expression in math is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that;

They each rent a pair of bowling shoes for $2.00.

They each play two games for a total of 4100.

They each buy a soda for $1.50.

Now,

Cost of shoes for eight friends = 8 x 2.00 = $16.00

And, Cost for playing two games = 8 x 4100 = $32,800

And, Cost of soda for eight friend = 8 x 1.50 = $12

Thus, Total cost = $16.00 + $32,800 + $12.00

                        = $32,828

So, The expression for the total amount is;

⇒ $16.00 + $32,800 + $12.00 = $32,828

Let the width of the rectangle be w.

Let the length of the rectangle be l.
