Solve simultaniously 2x-y=3 3x+2y=8

2 answers:

8 0

ANSWER: ( 0.75 , 2 )

EXPLANATION:
To find the system of solutions, solve the 2 equations.
(1) Find what you can multiply with to get the same number in the second equation.
(2) Multiply equation by -2
(3) New equation:
-4x - 2y = -6
3x + 2y = 8
(4) Add both equations
(5) New equation:
7y = 14
(6) Divide both sides by 7
(7) New equation:
Y = 2
-
Now find X
(1) Substitute y with a equation
(2) 3x + 2 (2) = 8
(3) 3x + 4 = 8
(4) Subtract 4 both sides
(5) 3x = 4
(6) Divide 3 both sides
(7) x = 0.75

C&A Museum has three million visitors per year. Each visitor spends an averageof 1 hour in the museum. What is the average n

Alona [7]

Answer:

1250 visitors per day

Step-by-step explanation:

Number of visitors per year = 3,000,000

Number of days open per year = 300

Number of hours = 9a.m to 5pm = 8 hours

Number of visitors per hour :

Number of visitors per year / (number of days per year * number of hours per day)

3000000 / (300 * 8)

3000000 / 2400

= 1250 visitors per day

If a wheel with a radius of 50 inches spins at a rate of 500 revolutions per minute, find the approximate linear velocity in mil

Artyom0805 [142]

Answer:

The linear velocity in miles per our is 14789400 mph .

Step-by-step explanation:

Given as :

The radius of wheel = 50 inches

So, the diameter of wheel = 2 × radius = 2×50 = 100 inches

Or, Diameter = 100 × 1.57 miles = 157 miles

The number of revolution per minutes = 500 RPM

or, The number of revolution per hours = 500 × 60 = 30,000 RPH

Now, Circumference of wheel = $\pi$ ×diameter

Or, C = 3.14 × 157 = 492.98 miles

So, Distance cover by wheel = C × RPH × Time in hour

or, D = 492.98 × 30,000 × Time in hour

And Velocity = $\dfrac{\textrm Distance in miles }{\textrm Time in hour}$

or, V = $\dfrac{\textrm 492.98 × 30,000 × Time in hour }{\textrm Time in hour}$

or, V = 14789400 miles per hour

Hence The linear velocity in miles per our is 14789400 mph . Answer
