Can you please help me on 6(1+n)=8n-3(n-7)
Nana76 [90]

Answer:

n = 15

Step-by-step explanation:

6(1+n)=8n-3(n-7)

Distribute

6 +6n = 8n -3n +21

Combine like terms

6+6n = 5n +21

Subtract 5n from each side

6+6n-5n = 5n-5n +21

6 +n = 21

Subtract 6 from each side

6-6+n = 21-6

n = 15

PLEASE HELP FAST!!!
grigory [225]

Answer:

x = 9

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

\frac{x-1}{6} = \frac{16}{12} ( cross- multiply )

12(x - 1) = 96 ( divide both sides by 12 )

x - 1 - 8 ( add 1 to both sides )

x = 9
