Answer:
PQ = 3.2
Step-by-step explanation:
PQ = PR - QR
PQ = 4.8 - 1.6
PQ = 3.2
Answer: 3 in.
Step-by-step explanation:
Given
The base of the triangle is 
The area of the triangle is 
Solve mixed fraction
Base is
Area is
The area of the triangle is given by
Insert the values to get the height
So we know there are 5 red and 12 silver marbles, together making 16 marbles.
This would mean that there is a 5/17 chance of choosing a red marble.
When you do the math to convert 5/17 into a decimal, it turns into being a .29 chance.
Convert .29 into a decimal, and you know that you have a 29% chance of grabbing a red marble.
Hope this helped!

Step-by-step explanation:
Solve the system via elimination (add the equations):
-10y + 9x = -9
+ (10y + 5x = -5)
-----------------------
14x = -14
x = -1
Plug in the value for 'x' into the second equation:
-10y + 5(-1) = -5
Solve for y:
-10y - 5 = -5
--> -10y = 0
--> y = 0
x = -1
y = 0
The base is 11 ft and the legs are both 19ft.
x+2x-36+2x-36=588
Addition Property of Equality
x+2x+2x=660
Combine Like Terms
5x=660
Division Property of Equality
x=132in
2(132)-36=228in
132in÷12=11ft
228in÷12=19ft
