N+2n+20-4=12+3n
3n+20-4-12=12-12+3n
3n+4=3n
3n/3 + 4= 3n/3
n+4=n
n+4-4=n-4

The swimming team has competed in 45 races this season. They have won 30 races so far. How many races will the team need to win

tatuchka [14]

Answer:

15 races

Step-by-step explanation:

The team has competed in 45 and has won 30. So the success rate is:

Success rate is:

$Sccess\ rate=r= \frac{30}{45}*100\\ =66.7\ percent$

We have to find the number of races the team needs to win for 75% success rate

Which means that

$r = \frac{30+x}{45+x} = 0.75\\$

We have to solve the equation for x

$\frac{30+x}{45+x}=0.75\\ 30+x = 0.75(45+x)\\30+x=33.75+0.75x\\x-0.75x=33.75-30\\0.25x=3.75\\x=\frac{3.75}{0.25}\\ x=15$

The team needs to win 15 races to get 75% success rate ..
