Answer: 40%
Step-by-step explanation:
700 - 500 = 200
200 / 500 = 40%
If the ratio of miles is
.. mr : mrs = 3 : 1
The total number of "ratio units" is 3+1 = 4, so each one stands for 3200/4 = 800 miles.
Mr Storey drove 3*800 = 2400 miles
Mrs Storey drove 1*800 = 800 miles
1: 9x+3
2: 3m^2+9m-7
3: 3x^2+3y^2+y+4
Those are all of the answers in order! I hope this helps.
