5[3(x+4)-2(1-x)]-x-15=14x+55 what is x
1 answer:
Answer:
The value of x is 2
Step-by-step explanation:
Given expression as :
5 [ 3 (x + 4) - 2 (1 - x) ] - x - 15 = 14 x + 55
Or , 5 [ 3 x + 12 - 2 + 2 x ] - x - 15 = 14 x + 55
Or, 5 [ 5 x + 10 ] - x - 15 = 14 x + 55
Or, 25 x + 50 - x - 15 = 14 x + 55
Or , 24 x + 35 = 14 x + 55
Or, 24 x - 14 x = 55 - 35
Or, 10 x = 20
∴ x = = 2
Hence The value of x is 2 . Answer

Answer:
Step-by-step explanation:
There was no figure but the question is clear
Volume of a cylinder is given by the formula
where r is radius of base of cylinder, h is the height
Volume of a cone is given by
where r is the radius of base of cone, h is the height
The radius of the cylinder = (diameter) =
(12) = 6cm
Height of cylinder = 15cm
Volume of cylinder
Radius of cone = (radius of cylinder) =
(6) = 3 cm
Height of cone same as height of cylinder = 15cm
Volume of cone,
Difference is the volume of the remaining solid
