Whould anyone mind helping please. The first box says 6.25x+12x=30.75 the second box says 6.25x+12=30.75 3rd box says 6.25x+30.7

Answer:

The correct equation is: 6x+12 = 30.75

And 3 people went to the movies

Step-by-step explanation:

We will write the equation to represent this scenario.

Let x be the number of people who went for movies.

Then the price of ticket for x people will be: 6.25x

They spent $12 on refreshments and a total of $30.75 so the equation will be:

$6.25x+12=30.75$

solving the equation will give us total number of people

So,

$6.25x+12 = 30.75\\6.25x = 30.75-12\\6.25x = 18.75\\\frac{6.25x}{6.25} =\frac{18.75}{6.25}\\x = 3$

Hence,

The correct equation is: 6x+12 = 30.75

And 3 people went to the movies

cluponka [151]

Answer:

$20.

Step-by-step explanation:

Given:

In the clip from the Simpsons, Ralph charges Bart twice the fair from Tucson to Flagstaff, minus 2/3 the fair from Albuquerque to El Paso.

It costs $40 to travel from Tucson to Flagstaff,

And $90 to travel from Albuquerque to El Paso.

Question asked:

How much does Bart need to pay ?

Solution:

Fair to travel from Tucson to Flagstaff = $40

Fair to travel from Albuquerque to El Paso = $90

<u>As Ralph charges Bart twice the fair from Tucson to Flagstaff, minus 2/3 the fair from Albuquerque to El Paso. </u>

$Bart\ need\ to\ pay=2 \times\$40 - \frac{2}{3} \times\$90\\ \\$

$=80-\frac{180}{3} \\ \\ =80-60\\ \\ =20$

Thus, Bart need to pay $20.
