hi
if x= 2+4y-5 then x-2 +5 = 4y so y = (x-2+5) /4 = ( x+3) /4
conclusion y = (x+3)/4
Answer:
Step-by-step explanation:
This is how we do it in college, I hope I can be of some help.
First, you multiple 9.6 miles with 5 minutes. Then, you divide your answer with 0.4 miles. Next, you cancel the two mile units because of division and then be left with 120 minutes.
9.6 miles x <u> 5 minutes </u> = <u> 48 miles x minute </u> = 120 minutes
0.4 miles 0.4 miles
Diameter of the larger gear х см
1/4х = 16 - 2.5
1/4x = 13.5
x = 13.5 * 4
x = 54 cm - diameter of the larger gear /
