serious [3.7K]

x+y+z=1

x=1/(y+z)

1/(y+z)-2y+3z=2  

1-2y²-2yz+3yz+3z²=2(y+z)

(1-2y²+yz+3z²)/2=y+z

z=(1-2y²+yz+3z²)/2 -y/1

z=(1-2y²+yz+3z²-2y)/2

How many hours will a car traveling at 65 miles per hour take to catch up to a car traveling at 55 miles per hour if the slower
son4ous [18]

It will take the first car 5.5 hours to catch up to the second car.

Step-by-step explanation:

Speed of second car = 55 miles per hour

As the car has started one hour before; it has already traveled

Distance = Speed * Time

Distance = 55*1 = 55 miles

Let,

x be the number of hours.

Distance covered in x hours = 55x

S(x) = 55x+55

Speed of first car = 65 miles per hour

Distance covered in x hours = 65x

F(x) = 65x

For catching up;

F(x) = S(x)

65x=55x+55\\65x-55x=55\\10x=55

Dividing both sides by 10

\frac{10x}{10}=\frac{55}{10}\\x=5.5

It will take the first car 5.5 hours to catch up to the second car.

-2x + 6y = 6<br> -7x + 8y = -5
AleksandrR [38]

Answer:

x=-2\\y=2

Step-by-step explanation:

-2x+6y=6\\-7x+8y=-5

Let's multiply the first equation by 7 and the second equation by -2

(7)(-2x+6y=6)\\(-2)(-7x+8y=-5)

-14x+42y=42\\14x-16y=10

Now add them together. In this step, x is eliminated.

26y=52

Divide by 26.

y=\frac{52}{26}\\ y=2

Now plug this into any of the two equations to find x.

-2x+6y=6\\-2x+6(2)=6\\-2x+12=16\\-2x=16-12\\-2x=4\\x=\frac{4}{-2}\\ x=-2
