Solve by Elimination:
6y+5x=8
2.5x+3y=4
Multiply the second equations by 2:
5x+6y=8
we know see that both equations are the same line, this means that there is an infinite amount of solutions to the equation
Answer:
The 15th visitor
Step-by-step explanation:
You have to find the LCM of the two numbers given by multiplying the chances that a visitor gets either a bumper sticker or a key chain.
1/3 x 1/5 = 1/15.
This means that every 15 people that visit the museum get both the bumper sticker and the key chain but since 15 is the lowest positive multiple of itself, the 15th visitor to the museum every day will be the first to get both items.
Answer:
Pythagorous Theorem
Step-by-step explanation:
in this case
Answer:
x = 48
Step-by-step explanation:
First find y
52+y+59 = 180 since they from a straight line
y = 180-59-52
y = 69
Then we know the angles of a triangle add to 180
x+y+63 = 180
x+69+63 = 180
x = 180-69-63
x =48
Answer:
Second option is correct
Step-by-step explanation:
Given:
Central angle = 15°
Radius of the circle = 9 in
Arc length = ?
Given formula is
Where n is the central angle of the sector.
Write the given formula for Arc length of the sector.
We know that the the circumference of the circle is 
, where r is the radius of the circle,
Now we substitute central angle value and radius value in above equation.
----------(
)
Divide the numerator and denominator by 5.
Therefore the arc length of the sector is
