Answer:

6x-6y-16=0

Step-by-step explanation:

Consider the following system of equations:

a_1x+b_1y+c_1=0\\\\a_2x+b_2y+c_2=0

The system of equations has infinite solutions if \frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}

One equation is 3x-3y=8

3x-3y-8=0

Take another equation as 6x-6y-16=0

So, the two equations are 3x-3y-8=0 and 6x-6y-16=0

a_1=3,b_1=-3,c_1=-8,a_2=6,b_2=-6,c_2=-16

\frac{a_1}{a_2}=\frac{3}{6}=\frac{1}{2}\\  \frac{b_1}{b_2}=\frac{-3}{-6}=\frac{1}{2}\\  \frac{c_1}{c_2}=\frac{-8}{-16}=\frac{1}{2}

So,

\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}

Therefore, another equation can be 6x-6y-16=0

A deck of ordinary cards is shuffled and 13 cards are dealt. What is the probability that the last card dealt is an ace?
alexandr1967 [171]

Answer:

The probability that the last card dealt is an ace is \frac{1}{13}.

Step-by-step explanation:

Given : A deck of ordinary cards is shuffled and 13 cards are dealt.

To find : What is the probability that the last card dealt is an ace?

Solution :

There are total 52 cards.

The total arrangement of cards is 52!.

There is 4 ace cards in total.

Arrangement for containing ace as the 13th card is 4\times 51!.

The probability that the last card dealt is an ace is

P=\frac{4\times 51!}{52!}

P=\frac{4\times 51!}{52\times 51!}

P=\frac{4}{52}

P=\frac{1}{13}

Therefore, the probability that the last card dealt is an ace is \frac{1}{13}.

Four friends plan to rent a car to go on a camping trip. They will drive a total of 450 miles. The cost of gasoline is​ $2.20 pe
Vlada [557]

Answer:

t = (m / g) * p

Step-by-step explanation:

Since we are given a variable for every part of the equation that we need we can go ahead and create the following equation where t equals the total cost

t = (m / g) * p

In this equation, we need to first divide the total number of miles by the number of miles that the car gets per gallon. This would give us the total number of gallons that the car would use during the entire trip. We then multiply the number of gallons by the price per gallon to get the final cost of the entire trip.
