The absoulte vaue of 300-48t is 30=29=-4
6 students received an A.
30 multiplied by .2 (you change percent to decimal) is 6.
Is there more to the question,
It is really simple. The ratio between both the triangles is 7, so you just divide 49 by 7(it gives you 7) to get the value of x. The answer is option (a) 7.
Hope This Helped!
Good Luck!
