One foot is equal to 12 inches. One inch is equal to 2.54 centimetres. Therefore, 4 feet 9 inches is equal to (2.54 x 12 x 4) + (2.54 x 9) = 144.78 centimetres.
i assume you mean what does x equal in this case. x = 0 here. x-5+9=4 x+4=4 x=0
x = 11 (x+9)/5 = 4 x + 9 = 20 (multiply both sides by 5) x = 11
x= 1.67(rnd) 5= -4+3x+4 5- -4= 9 9=3x+4 9-4=5 5=3x x= 1.67(rnd)
There are 12 inches in one foot, therefore 4 feet 9 inches is equal to (4 x 12) + 9 = 57 inches.
