eight time the difference of a number and 2 is the same as 3 times the sum of the number and 3

8* (n-2) = 3*(n+3)

distribute

8n-16 =3n+9

subtract 3n from each side

5n-16 =9

add 16 to each side

5n = 25

divide by 5

n=5

Answer:

∠ACD = 33.5°

Step-by-step explanation:

The arc length will be twice ∠ ABD,

∠ABD will equal ∠ACD because they subtend the same arc length.

3x + 7 = 2(2x - 6.5)

3x + 7 = 4x - 13

x = 20

∠ABD = (2(20) - 6.5) = 33.5

2(4w+7)=62 <br><br> Whats the answer how do I do it?

blondinia [14]

$2(4w + 7) = 62$

Divide both sides by 2

$\frac{2(4w + 7)}{2} = \frac{62}{2} \\$

$4w + 7 = 31$

Subtract both sides 7

$4w + 7 - 7 = 31 - 7$

$4w = 24$

Divide both sides by 4

$\frac{4w}{4} = \frac{24}{4} \\$

$w = 6$
