Answer:
5x-6+7x+12=180
Step-by-step explanation:
5x+7x = 12x
12x - 6 +12 = 180
add 12 and -6 to get 6.
12x + 6 = 180
subtract 6 from both sides to get 174.
12x = 174.
now divide both sides by 12 to get x = 14.5 or 29/2 which cancels out to 6
0.37
1 2/3 divided by 4 1/2
Are there any answer choices??
600 = 45x (x= minutes)
13.3333333=x
1*(2/3) = 80 minutes
80x= 13.333333*80
