X=-1/3y+4/3 X=2Y+6 Help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
jonny [76]
Both equal so set equal to each other
-1/3y+4/3=2y+6
times both sides by 3
-y+4=6y+18
add y to both sides and minus 18 both sides
-14=7y
divide both sides by 7
-2=y

sub back
x=2y+6
x=2(-2)+6
x=-4+6
x=2

The results of a swim meet are shown. Who swam the fastest? Explain your reasoning.
kobusy [5.1K]

Answer : The Susana swam the fastest.

Step-by-step explanation :

Speed : It is defined as the distance traveled per unit time.

Formula used :

Speed=\frac{Distance}{Time}

First we have to determine speed of the following persons.

<u>For Tawni :</u>

Distance = 50 m

Time = 40.8 s

Speed=\frac{Distance}{Time}=\frac{50m}{40.8s}=1.225m/s

The speed of Tawni is, 1.225 m/s

<u>For Pepita :</u>

Distance = 100 m

Time = 60.2 s

Speed=\frac{Distance}{Time}=\frac{100m}{60.2s}=1.661m/s

The speed of Pepita is, 1.661 m/s

<u>For Susana :</u>

Distance = 200 m

Time = 112.4 s

Speed=\frac{Distance}{Time}=\frac{200m}{112.4s}=1.779m/s

The speed of Susana is, 1.779 m/s

From this we conclude that, in this problem meter affects the response and the speed of Susana is more than the Pepita and Tawani.

Thus, Susana swam the fastest.
