12. USING EQUATIONS So far this baseball season, you have 12 hits out of 60 times at-bat. Solve the equation 0.360 = (12 + x)/(60 + x) to find the number of consecutive hits you need to raise your batting average to 0.360.
0.36 = (12 + x)/(60 + x) cross multiply 0.36x + 21.60 = 12 + x 21.60 - 12 = x - 0.36x 9.60 =0.64x divide both sides by 0.64 x =9.60 / 0.64 x = 15 - number of consecutive hits.
