2v+18=16-4(v+7) how does one do this

v = - 5

distribute right side of equation and simplify

2v + 18 = 16 - 4v - 28

2v + 18 = - 12 - 4v ( add 4v to both sides )

6v + 18 = - 12 ( subtract 18 from both sides )

6v = - 30 ( divide both sides by 6 )

v = = - 5

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

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
