Answer:
no, because they need a 1 or a fraction yo be a mixed number..... I hope that helps
Step-by-step explanation:
It would take 6.5 years if I’m correct.
You answer this by isolating the variable. This means you work on the side where the variable is and do reverse operations to undo what was done in reverse "pemdas" order.
Start by translating and writing an equation:
Let x be the number
so:
12-1/4 x = 22
now subtract 12 from both sides. (because 12-12=0)
12-12-1/4 x =22-12 (now simplify)
-1/4 x = 10
next you want 1 x, not -1/4 x.... so to get to 1 you multiply both sides by the reciprocal of -1/4 which is -4/1
-1/4 * -4/1 x = 10 * -4/1 (multiply and simplify)
x = -40
2/9 play strings. 1/3 x 2/3 = 2/9. Think of it this way, if the school has 18 students and 1/3 play an instrument, 6 students play an instrument. Of those 6 students, 2/3 or 4 play a string instrument. 4/18 simplifies to 2/9
