At the city museum, child admission is $5.20 and adult admission is $9.90 . On Monday, twice as many adult tickets as child tick
DiKsa [7]
To solve this, I would just find what two adult tickets and one child ticket wold be worth.

To find that, just do:

5.20 + 9.90 * 2, which makes 25.

So now you just find how many 25s are in 900, or 36.

So 36 children's tickets were sold that day.

Hope I helped :)

Okay, I'm going to be adding more but what is 4/10 x 3?
Marat540 [252]

Answer:

6/5 or 1 1/5

6/5 is an improper fraction, so I didnt know if youd need an improper one or a proper one. They both are the same thing though :)

Step-by-step explanation:

4/10*3

They both need to be a fraction, and any number over 1 = that number. So,

4/10*3/1

4*3=12

10*1=10

12/10

Then, you have to simplify the fraction.

6/5 (bc 2 goes into 12 6 times and 2 goes into 10 5 times)

or 1 2/10= 1 1/5

Hope this helps. Plz give brainliest. Also, plz sub to Kgirl633 on yt.

Please help I’m not sure how to do this and I’m struggling
Alexeev081 [22]

1.1     Pull out like factors :

  -8x - 2  =   -2 • (4x + 1)

2.1    Divide both sides by  -2

Remember to flip the inequality sign:

2.2    Divide both sides by  4  

     x+(1/4)  ≥ 0

Solve Basic Inequality :

2.3      Subtract  1/4  from both sides

           x ≥ -1/4
