x =11

Step-by-step explanation:

We can use ratios to solve

RS             ST  

------- = ---------

MN           NO

3             5.5  

------- = ---------

6            x

Using cross products

3x = 6*5.5

3x =33

Divide by 3

3x/3 = 33/3

x =11

Answer:

11 because as you see 3 and 6 if you divide it the scale factor is 1/2 so you just do 5.5 times 2 and get 11

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

m - 4m = -6

<u>Step 2: Solve for </u><em><u>m</u></em>

  1. Combine like terms:                    -3m = -6
  2. Divide -3 on both sides:              m = 2

<u>Step 3: Check</u>

<em>Plug in m into the original equation to verify it's a solution.</em>

  1. Substitute in <em>m</em>:                     2 - 4(2) = -6
  2. Multiply:                                 2 - 8 = -6
  3. Subtract:                                -6 = -6

Here we see that -6 does indeed equal -6.

∴ m = 2 is the solution to the equation.

Sarawongs school is selling tickets to the anual talent show on the first day of ticket sales the school sold 1 adult ticket and
vaieri [72.5K]

Price of one adult ticket is $9 and price of one student ticket is also $9.

Step-by-step explanation:

Let,

Adult ticket = x

Student ticket = y

According to given statement;

x+2y=27   Eqn 1

2x+2y=36   Eqn 2

Subtracting Eqn 1 from Eqn 2;

(2x+2y)-(x+2y)=36-27\\2x+2y-x-2y=9\\x=9

Putting x=9 in Eqn 1;

9+2y=27\\2y=27-9\\2y=18

Dividing both sides by 2;

\frac{2y}{2}=\frac{18}{2}\\y=9

Price of one adult ticket is $9 and price of one student ticket is also $9.
