a total of 408 tickets were sold for the school play. They were either adult tickets or student tickets. The number of students

Mama L [17]

Given Situation:
=> There are 408 total of ticket sold for a school play
=> 3 times of the tickets are sold to students compare to the adults
=> So the ratio of the given situation is 1 : 3
=> Now, 1 + 3 = 4
Since, we need 4 parts, let’s divide 408 by 4
=> 408 / 4 = 102 – the number of tickets for adults
=> 102 x 3 = 306 – the number of tickets for students
=> 102 : 306

The width of the triangle is 3/4 the length. The perimeter is 252cm. What is the width of the triangle.

ICE Princess25 [194]

Answer:

C). 54 cm.

Step-by-step explanation:

I think you mean a rectangle .

If the length is x then the width = 0.75x (because 3/4 = 0.75).

Perimeter = 2*length + 2*width.

252 = 2x + 2*0.75x

252 = 2x + 1.5x

252 = 3.5x

x = 252 / 3.5

= 72 which is the length,

The width = 3/4 * 72

= 54 cm.

Here is a story: Lin bought 4 bags of apples. Each bag had the same number of apples. After eating 1 apple from each bag, she ha

Setler [38]

Answer:

Let's define the variable x as the number of apples in each bag.

We know that she bought 4 bags, then the total number of apples that she has is:

Apples = 4*x

Now she eats one apple for each bag, then she eats 4 apples, so she now has:

Apples = 4*x - 4

And we know that this is equal to 28, then:

4*x - 4 = 28

now we can solve this for x.

4*x = 28 + 4 = 32

x = 32/4 = 8

x = 8

There are 8 apples in each bag.

For the diagram part, by a small online search y found the image that you can see below.

The diagram that correctly represents this situation is diagram C, where x represents the number of apples in each bag.
