Answer:4 meters

Step-by-step explanation:

About Elena we know that she moves at 60 meters each 15 seconds:

Distance     Time

  60m     →   15s

and we want to know how far she would go in only 1 second:

Distance     Time

  60m     →   15s

     x        →    1s

where x is the unknown distance, that we calculate as follows: multiply the cross quantities in the table and divide by the other number in the corner.

In one second she will travel 4 meters.

Triangle ABC is congruent to the Triangle DEF , EF=X^2 -7 , BC = 4X-2 ,Find the value of X? help guys
11111nata11111 [884]

Answer:

x=5

Step-by-step explanation:

Congruent triangles mean they have the same side lengths, so the equation here is x^2-7=4x-2. Then, solve the quadratic equation:

x^2-7=4x-2

x^2-4x-5=0

(x-5)(x+1)=0

x=5,-1

Since a side of a triangle can't be negative, the answer is 5.

At the movie theatre, child admission is $6.10 and adult admission is $9.20 . On Thursday, three times as many adult tickets as
natita [175]

Answer:

21 child tickets.

Step-by-step explanation:

Let x represent number of adult tickets and y represent number of child tickets.  

We have been given that on Thursday, three times as many adult tickets as child tickets were sold. We can represent this information in an equation as:

x=3y...(1)

We have been given that at a the movie theater, child admission is $6.10 and adult admission is $9.20.The all tickets were sold for a total of $707.70. We can represent this information in an equation as:

9.20x+6.10y=707.70...(2)  

Upon substituting equation (1) in equation (2), we will get:

9.20(3y)+6.10y=707.70  

27.6y+6.10y=707.70

33.7y=707.70

\frac{33.7y}{33.7}=\frac{707.70}{33.7}

y=21

Therefore, 21 child tickets were sold on Thursday.
