Answer:
0.2
Step-by-step explanation:
It's in it's simpiliest form because there's nothing you can cancel out without have an exact value for y. y is a variable therefore it can't be cancelled out without also having something to factor out from both the denominator and numerator sorry for not clearly understanding what you was asking
It’s Gonna be D bc 2/3x =y-1
Divide the total cost by 4:
272 / 4 = 68
It cost $68 for 1 tire
In 3 hours half of 700 would be 700/2=350
in 3 more hours, so 6 total, the half life would be 350/2 = 175
in 3 more hours, 9 total, the half life would be 175/2 = 87.5
in 3 more hours, 12 total, the live life would be 87.5 / 2 = 43.75
so it would be 12 hours to have less than 50 mg
