one month Miguel rented 5 movies and 3 video games for a total of $27. The next month he ordered 2 movies and 6 video games for
34kurt

Answer:

The price of each movie is $2.25

The price of each video games is $5.41  

Step-by-step explanation:

Given as :

Miguel rented 5 movies and 3 video games for a total cost = $27

Next day Miguel rented 2 movies and 6 video games for a total cost = $36

Let The cost of each movie = $m

And The cost of each video game = $v

Now, According to question

5 m + 3 v = 27            .....1

2 m + 6 v = 36          ...........2

Now, solving the equation

2 × (5 m + 3 v)  - (2 m + 6 v) = 2 × 27 - 36

Or, 10 m + 6 v - 2 m - 6 v = 54 - 36

Or, (10 m - 2 m) + (6 v - 6 v) = 18

Or, 8 m + 0 = 18

∴ m = \dfrac{18}{8} = \dfrac{9}{4}

i.e m = $2.25

So, The price of each movie =  m = $2.25

Again, put the value of m into eq 2

So, 2 × 2.25 + 6 v = 36  

Or, 4.5 + 6 v = 36  

Or, 6 v = 36 - 4.5

Or, 6 v = $32.5

∴ v = \dfrac{32.5}{6}

i.e v = $5.41

So, The price of each video games = v = $5.41

Hence, The price of each movie is $2.25 and

The price of each video games is $5.41  Answer

Answer:

Option 2

Step-by-step explanation:

Given

B = (-6,1)

B' = (-3,-2)

Step 1: Substitute the original and translated coordinates into (x,y) => (x+a,y+b)

B(-6,1) => B'(-6+a , 1+b) = B'(-3,-2)

Step 2: Write two equations

-6+a = -3 => a = -3+6 = 3

1+b=-2 => b = -2-1 = -3

Hence, we can conclude that Indira wrote the equations wrong which was her first error.

Therefore, Option 2 is correct ..
