5 1/6-[1 1/5+{2 3/4+5 1/2+x-(5/6-2/3)}]=2 61/120
Answers
Answer:
Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed. If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches, or 64 cubic inches. (Cubic inches can also be written in3.)
Answer:
Given 51/6 - [11 / 5 + {23 / 4 + 51 / 2 + x - ( 5 / 6 - 2 / 3 )}] = 261/120
now,
⇒ 51/6 - [11 / 5 + {23 / 4 + 51 / 2 + x - 1 / 4 }] = 261/120
⇒ 51/6 - [11 / 5 + { (124 - 4x) / 4 }] = 261/120
⇒ 51/6 - [11 / 5 + { 31 - x }] = 261/120
⇒ 51/6 - [11 / 5 + 31 - x ] = 261/120
⇒ 51/6 - [11 / 5 + 31 - x ] = 261/120
⇒ 51/6 - [(11 + 155 - 5x)/5] = 261/120
⇒ 51/6 - [166 / 5 - 5x / 5 ] = 261/120
⇒ 51/6 - 166 / 5 + 5x / 5 = 261/120
⇒ 5x / 5 = 261/120 - 51/6 + 166/5
⇒ 5x / 5 = (261 - 1020 + 3984) / 120
∴ x = 3225 / 120 is the correct value of x
