Answer:
-6
Step-by-step explanation:
-6/b-50=-49
step1;collect like terms
-6/b=-49+50
-6/b=1
step2;cross multiply
-6/b=1
-6=1b(1b can also be regarded as b)
b=-6

enters the irrational number category.
Integers numbers are the numbers without decimals between -infinity and infinity.
Natural numbers are the whole numbers from 1 to infinity.
Whole numbers are natural numbers + 0.
You must find the relative rates of both workers...
T=f/3 and J=f/2 so if they work together to clear the field then:
ft/3+ft/2=f make all terms have a common denominator of 6
(2/2)(ft/3)+(3/3)(ft/2)=(6/6)f
2ft/6+3ft/6=6f/6 multiply both sides by 6
2ft+3ft=6f divide both sides by f
2t+3t=6 combine like terms on left side
5t=6 divide both sides by 5
t=6/5 hr
t=1 1/5 hr
t=1 hr 12 min
The perimeter of the carpet is determined by its dimensions so the dimensions of the room are irrelevant to the question.
P=2(x+y) where x and y are the dimensions, here x and y equal 9 and 12 ft so
P=2(9+12)
P=2(21)
P=42 ft
