$b=a+3\\
c=a+6\\
a^2+b^2=c^2\\\\
a^2+(a+3)^2=(a+6)^2\\
a^2+a^2+6a+9=a^2+12a+36\\
a^2-6a-27=0\\
a^2-9a+3a-27=0\\
a(a-9)+3(a-9)=0\\
(a+3)(a-9)=0\\
a=-3 \vee a=9\\

Tresset [83]

Answer:

8 days

Step-by-step explanation:

We are told in the question:

Carlos has 4/5 of a tank of fuel in his car. He uses 1/10 of a tank per day.

How many days will his fuel last?

1/10 of fuel = 1 day

4/5 of fuel = x

Cross Multiply

1/10 × x = 4/5 × 1

x = 4/5 / 1/10

x = 4/5 ÷ 1/10

x = 4/5 × 10/1

x = 8 days

His fuel lasts for 8 days
