Answer:

(3,2)

Step-by-step explanation:

The system is

x + y = 5

x -y = 1

Add the equations to eliminate y

2x = 6----->x=3

Substitute this value in any equation

3+y = 5----->y=2

The solution is (3,2)

Fifteen times the square of a non-zero number is equal to 20 times number.What is the number? Its not 4/3
e-lub [12.9K]
The number is (2√3) / 3

To find the missing number, convert what it says in words to an equation:
15 {x}^{2}  = 20x
Divide both sides by 15:
{x}^{2}  =  \frac{20}{15}   \\  \\  {x}^{2}  =  \frac{4}{3}
Take the square root:
x =  \sqrt{ \frac{4}{3} }  \\  \\ x =  \frac{2}{ \sqrt{3} }  \\  \\ x =  \frac{2 \sqrt{3} }{3}

Each week, Rosario drives to an ice-skating rink that is 60 miles away. The round-trip takes 2. 75 hours. If he averages 55 mile
mart [117]

Rosario's average speed on her way home is 36.66 miles per hour.

<h2><u></u></h2><h2><u>Average speed</u></h2>

Given that each week, Rosario drives to an ice-skating rink that is 60 miles away, and the round-trip takes 2.75 hours, to determine, if she averages 55 miles per hour on his way to the rink, what is her average speed to return to his house, the following calculation must be made:

  • 55 = 1
  • 60 = X
  • 60 / 55 = X
  • 1.09 = X
  • 2.75 - 1.09 = 1.66
  • 55 = 1
  • 27.5 = 2
  • 55 / 3 x 2 = 36.66

Therefore, Rosario's average speed on her way home is 36.66 miles per hour.
