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
Snowcat [4.5K]

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

Anuta_ua [19.1K]
2 7/12 hours

X=101/2 - ( 3+4+1/4+2/3)

X=101/2 - 7 + (1/4+2/3)

1/4+2/3= 11/12

101/2 - 7 =3 1/5

X = 3 1/5 - 11/12 = 2 7/12

What is the first operation used to evaluate 5+7•6-2÷4
Kisachek [45]

Multiply 7x6 since when using pemdas, multiplication and division can be inverted, i.e. if multiplication is before division then you multiply and vice versa.


Hope this helps!
