5b
(ab/b) / (4a/5b) =(ab / b) * (5b / 4a) = (5ab2 / 4ab)= 5 / (4b)
Your equation cannot be solved. So we simplify using fun algebra! 4b + b = 5b
5ab-2ab+4a-b+5b = 3ab+4a+4b
5b = 8 therefore b = 8/5 therefore b = 1.6
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
5b
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
I Don't know the full song, but I can show the intro to start you off. B=blow - D=draw 5b - 5b - 5b - 4b - 5b - 6b - 4b
Ans. 2a-5b
(ab/b) / (4a/5b) =(ab / b) * (5b / 4a) = (5ab2 / 4ab)= 5 / (4b)
Your equation cannot be solved. So we simplify using fun algebra! 4b + b = 5b
5ab-2ab+4a-b+5b = 3ab+4a+4b
5b = 8 b = 8/5 or 1.6
-86
5b = 8 therefore b = 8/5 therefore b = 1.6
5a2 - 20ab - 25b2 = 5(a2 - 4ab - 5b2) = 5(a2 - 4ba - 5b2) since -5b*b = -5b2 and -5b + b = -4b, then = 5(a - 5b)(a + b)
