Answer:
The question is incomplete or there are details missing.
Step-by-step explanation:
From similar parameters, if by what they mean is that the football field measures 300feet in length, which is the dimension in length, this can also be in terms of metre.
The conversion factor between ft and metre is 1ft = 0.3048m
As such, we can only have variations or the length of the field measured may have ranges of measurement, but as it is the length of the field can not be expressed in terms of miles, the most reasonable vale of n we can get will be the least measurement in metres.
So if 60 marks is 40%do buildind blocks 40%+ 40 % 80% = 120 marks so ad 20 % which is 30 marks so full marks is 150
Answer: Non-proportional
Step-by-step explanation:
The unit rate for the gas per gallon is $3.17. You want to find out if that is equal to the amount you would pay for 10 gallons at once. If you multiply the unit rate by ten, you would get 10 gallons = $31.70
So...you know that it is not proportional
Answer:
Step-by-step explanation:
9y-4 = 50
9y = 54
y= 6
9y-4+7x+xy = 180
9(6)-4+7x+6x= 180
54-4+13x = 180
13x+50 = 180
13x = 130
x = 10
