5y-21=14

please help me I need the full method ​

5y-21=14

or, 5y = 14+21

or, 5y = 35

or, y = 35/5 = 7

Answer is 7.

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
