Answer:
x = 5/-8
Step-by-step explanation:
4x = 12x + 5
4x - 12x = 5
-8x = 5
x = 5/-8
 
        
             
        
        
        
Answer:
L = 15
Step-by-step explanation:
P = 2L + 2W
you know that P = 50, W=10
So you have to replace those values on the equation
50 = 2L + 2*(10)  --> Replace P and W
50 = 2L + 20  --> Multiply and now you are going to separate the unknown and the constants.
Remember that if you send a constant to the other side of the equal the sign will change to its opposite
50 - 20 = 2L  --> Solve the constants
30 = 2L    --> Now for the L, you have to leave it alone, so the 2 that is multiplying you have to send it to the other side of the equal but with the opposite operation,  the opposite operation of multiplying is dividing, so you have:
30/2 = L
L= 15
 
        
             
        
        
        
Answer:
V= volume of cone A=Ah A= πr2
A= area of base 3
H= height
V= (3.1416)(16)(15) 3.1416x16x15= 753.9
 3
V= 753.9 753.9÷3= 251.3 cu. in
 3
 Volume of the cone is 251.3 cu. in
I hope this helps you. Good luck!
