Glenn races his motorcycle 30 times last season. he finished first 12 times, second 5 times and crashed in 9 races. what percent of the races did he crash? set up a proportion and solve.

The sum of the first eight terms of an arithmetic progression is 9m + 14. the fifth term of the06 progression is 2m - 6, where m is a constant.given that the first term of the progression is 26,find the value of the common difference, d and thevalue of m.

Solving algebraic equations 2m+3=11

Rationalize the denominator- 12x/√x-10
