Answer:

Step-by-step explanation:

Question One

Multiply through by 2

2*1/2 * (2x + y ) = 21/2 * 2

Combine

2x + y = 21

Subtract 2x from both sides

y = 21 - 2x

Now equate the two given equations

y = 21 - 2x

y = 2x

Add 2x to both sides

2x = 21 - 2x

2x + 2x = 21

4x = 21

x = 21/4

x = 5 1/4

or

x = 5.25

Question 2

\dfrac{2x + 6}{(x + 2)^2} - \dfrac{2}{(x + 2)}

multiply numerator and denominator of the second fraction by (x + 2)

\dfrac{2x + 6}{(x + 2)^2} - \dfrac{2(x + 2)}{(x + 2)*(x + 2)}

Remove the numerator brackets in the right hand fraction. Look out for the minus sign.

\dfrac{2x + 6}{(x + 2)^2} - \dfrac{2(x + 2)}{(x + 2)^2}\\\\\dfrac{2x + 6- 2x - 4}{(x + 2)^2}}\\\\\dfrac{2}{(x + 2)^2}

an Olympic swimming pool is 6 meters long how many lives will and have to swim in order to swim 1 kilometer
vlada-n [284]
I'm guessing you mean laps here
Let's find out how many meters are in a kilometer. Kilo is 1000 more than a single unit, so for every kilometer you have 1000 meters.

so divide 1000/6 to find the amount of laps to swim 1 kilometer
