8n + 2 = 5n + 11 , does anyone one know the answers

n=3

Step-by-step explanation:

8n + 2 = 5n + 11

Subtract 5n from each side

8n-5n + 2 = 5n-5n + 11

3n+2 = 11

Subtract 2 from each side

3n+2-2 = 11-2

3n = 9

Divide by 3

3n/3 = 9/3

n =3

n=3

Step-by-step explanation:

Let's do the algebra step-by-step.

8n+2=5n+11

 -2       -2

8n=5n+9

-5n   -5n

3n=9

/3  /3

n=3

Hope this helps :D

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
