13=-4k+9
Whats k?
Pl help me due today

Explanation:

13 = -4k + 9

Flip the equation

−4k + 9 = 13

Subtract 9 from both sides

−4k + 9 − 9 = 13 − 9

−4k = 4

Divide both sides by -4

−4k / -4 = 4 / -4

Simplify

k = -1

k=-1

Step-by-step explanation:

13=-4k+9

switch sides

-4k+9=13

subtract 9 from both sides

-4k+9-9=13-9

simplify

-4k=4

divide both sides by negative 4

-4k/-4=4/-4

simplify

k=-1

hope this helps :) have a nice day !!

alot

step-by-step explanation:

its a wood chuck that can chuck wood

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
