oee [108]3 years ago
3 0

Answer:

\small \sf \frac{2}{3}   = x \\

Step-by-step explanation:

Solve for x;

2x - ( x - 2 ) = 4x

distribute minus sign through parantheses

  • 2x - x + 2 = 4x

combine like terms

  • x + 2 = 4x

subtract x from both side

  • x - x + 2 = 4x - x
  • 2 = 3 x

Divide each side by 3

\small \sf \frac{2}{3}  =  \frac{3x}{3} \\

\small \sf \frac{2}{3}  = x\: \\

lisov135 [29]

Answer:

40 more kids chose baseball over basketball.

Step-by-step explanation:

The best way to go about this is to use benchmark percentages.

For baseball, 25% of 800 people chose that, so we can do 800/4 to get 200, so 200 students chose baseball

For basketball, we could do 800/5 but that isn't mental math, so we can do 10% of 800 is 80 and 80*2=160. So 40 more kids chose baseball over basketball.
