Which equation represents "the sum of eight times a number and seven is twice the number"? 8(7 + 2n) 8n = 7 + 2n 7n + 8 = 2n 8n + 7 = 2n

D.

Step-by-step explanation:

Let N represent the number.

We are asked to find the equation that satisfies the given description.

8 times the number would be .

The sum of eight times a number and seven would be .

Twice the number would be .

To find our required equation, we will equate the sum of eight times a number and seven to twice the number as:

Therefore, option D is the correct choice.

step-by-step explanation: yes

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
