Answer:

The correct answer is - 12.

Step-by-step explanation:

Given:

Total number of people = y = 39x+50

Total amount spent y = 518

Solution:

The equation for the number of people who attended the dinner

y = 39x+50

The cost of dinner is equally divided by number of people =

then, 518 = y

placing value, 518 = 39x+50

x = (518-50)/39

= 468/39

= 12

Then number of people attended the dinner = 12

There are 84 boys in the 6th grade class. If boys make up 30% of the 6th graders, how many students are in this whole 6th grade
koban [17]
<h3>Answer:  280</h3>

Work Shown:

x = number of students in the 6th grade class

30% = 30/100 = 0.30

30% of x = 0.30x this is equal to 84 since "30% of the 6th graders are boys (and there are 84 boys in sixth grade)", so we say 0.30x = 84

Divide both sides by 0.30 to isolate x

0.30x = 84

0.30x/0.30 = 84/0.30

x = 280

So there are 280 students overall in the 6th grade class.

A recipe calls for 1.5 cups of raisins for 18 cookies how many cups of raisins must be used for making 30 cookies. please break
Zanzabum

Lets list what we know:

1.5 cups = 18 cookies

How many cups in 1 cookie will help us find the answer:

1.5 / 18     (1.5 cups per 18 cookies)

divide both sides by 1.5 (to get how many cookies in 1 cup)

1 / 12        (1 cup = 12 cookies)

Now, how many times does 12 fit in 30?

30/12 = 2.5

This means it takes 2 and a half cups of raisins to get 30 cookies.

If anything is still unclear please comment,

Hope this was helpful

Have a great day!
