Answer:

10 Seconds

Step-by-step explanation:

Speed of Elene = 3m/s

Speed of Abbi = 2m/s

Let the  time be t  seconds taken by Elene to  catch abbi.

Distance for any speed S and time is calculated by formula given below

Distance = speed * time

  • distance covered by Elene in time t =  3m/s * t = 3t m  -->equation A
  • distance covered by Abbi in time t =  2m/s* t = 2t m  --> equation B

Since it is given that Elene has given abbi 10 m head start it means that

Elene has to run extra 10 meters than Abbi to catch abbi.

Thus we can say that

distance run by Elene = 10 m + distance run by Abbi

Substituting that value distance run by Elene from equation A

and distance run by Abbi from equation B

we have

3t = 2t +10

=>3t - 2t = 10

=> t = 10

Therefore it will take 10 second for elene to catch abbi.

Answer:

the answer for X is -6

Step-by-step explanation:

g(X)=5/2x -1 and g(X)= - 1

sub -16 on g(X)

-16=5/2x -1

-16+1 = 5/2x

-15 = 5/2x

divide both sides by 5/2

X= -6

Alenkasestr [34]

Answer:

See explanation

Step-by-step explanation:

9x(-2y+5x)-4xy(6x-3y)

By the distributive property this is equal to:

9x(-2y)+9x(5x)-4xy(6x)-4xy(-3y)=\\\\-18xy+45x^2-24x^2y+12xy^2

Hope this helps!
