Answer:
a. $3600
b. 6:5
Step-by-step explanation:
Put the question into an equation:
8x - 1/4 x 8x = 5x + 450
(simplify before solving) 6x = 5x + 450
(solve) 6x-5x = 450
x = 450
This means that Jimmy had 8 x 450 $ to start with = 3600
you can check this by subtracting a quarter of 3600 from 3600 and also multiplying 450 by 5 and then obtaining their difference. You get 450!
Now ratio of new amounts:
Jimmy now has: $2700
John still has: $2250
so ratio is 2700:2250
simplify to 6:5
Hope this helps

Answer:
sorry i only know the answer of c
it's 8.2 gallons
Step-by-step explanation:
12 gallons = 420 miles
12 gallons = 420 miles? gallons =287 miles
420 miles ÷ 12 gallons = 35miles/gallon
420 miles ÷ 12 gallons = 35miles/gallon287 miles ÷ 35 miles/gallon = 8.2 gallons
I think it’s 3 because it’s just how I think it is I’m probably not correct but I think it’s 3
6x²-5x-4=0
x=(-b+/√b²-4ac)/2a
D=b²-4ac=25+4*6*4=121, √D=√121=11
x=(5+/-11)/12
x1=-6/12=-1/2
x2=16/12=4/3
