A car travels at the rate of x miles per hour for y minutes. which of the following gives the number of miles the car has travel
harkovskaia [24]

Given that speed of car = x miles per hour

Time of travel = y minutes = y/60 hours

(Because there are 60 minutes in an hour)

We have to calculate distance travelled so we will use formula

Distance = speed * time

Distance = x * y/60

Distance = xy/60

Hence choice d) xy/60 is the final answer.

A family has two cars. The first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of
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.

Help with my algebra homework
Maru [420]

Let's solve your equation step-by-step.

2x /5 + 3 = x/10 - 1

Step 1: Simplify both sides of the equation.

2x /5 + 3 =  x/10 - 1

2/5x + 3 = 1/10x - 1

Step 2: Subtract 1/10x from both sides.

2/5x + 3 - 1/10x = 1/10x - 1 - 1/10x

3/10x + 3 = -1

Step 3: Subtract 3 from both sides.

3 /10x + 3 - 3 = -1 - 3

3/10x = -4

Step 4: Multiply both sides by 10/3.

(10/3) * (3/10x) = (10/3) * (-4)

x = -40/3

Determine the quotient and remainder F(x)=6x^4+12x^3+24x^2+<br> 23x+18 is divided by g(x)=2x^2+2x+4
Mekhanik [1.2K]
The only way to do this one is by long division which I can't figure out how to show here. There are some great examples online if you google long division with polynomials.

The answer is 3x^2+3x+3 with a remainder of 5x+6 who's is usually shown as (5x+6)/2x^2 +2x+4 which was the divisor g(x).
