Hello,

Rational numbers are numbers that can be represented by fractions that consist of integers.

In this case, B. -7/3 is already a fraction that consists of integers, so it is a rational number.
C. square 3 is = 3^{2} = 9, which can be represented by 9/1, so it is also a rational number.

A and D are incorrect as they cannot be represented by fractions that consist of integers.

The answers are B and C.

Hope this helps!

Lubov Fominskaja [6]

<u>Answer:</u>

First car:  35 gallons

Second car: 15 gallons

<u>Step-by-step explanation:</u>

Assuming x to be the gas consumed by 1st car and 50 - x to be the gas consumed by 2nd car.

We know that:

Distance traveled = fuel efficiency × gas consumed

20x+35(50-x)=1225

20x+1750-35x=1225

35x-20x=1750-1225

15x=525

x=35

So 50 - x = 50-35=15

Therefore, first car consumed 35 gallons while second car consumed 15 gallons.
