The bottom of ignacio's desktop is 74.5\,\text{cm}74.5cm74, point, 5, space, c, m from the floor. ignacio sits in his adjustable chair, and the tops of his legs are 49.3\,\text{cm}49.3cm49, point, 3, space, c, m from the floor. each clockwise rotation of the knob on the chair raises ignacio's legs by 4.8\,\text{cm}4.8cm4, point, 8, space, c, m.
write an inequality to determine the number of clockwise rotations, rrr, ignacio could make with the knob without his legs touching the desk.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
