Answer:

n = 20/7

Step-by-step explanation:

4n+5=25-3n

Add 3n to each side

4n+3n+5=25-3n+3n

7n +5 = 25

Subtract 5 from each side

7n+5-5=25-5

7n = 20

Divide by 7

7n/7 = 20/7

n = 20/7

Alla [95]

By the segment addition postulate,
AC + CE = AE so AC = AE - CE
AC = (x+50) - (x+32)
AC = x+50-x-32
AC = 18

Which equation is equivalent to 3/5 = x+1/y-2 when solved for x?

Otrada [13]

Answer:

It's the second option x = (3y - 11) / 5.

Step-by-step explanation:

3/5 = x+1/y-2

Cross multiplying:

3(y - 2) = 5(x + 1)

3y - 6 = 5x + 5

5x = 3y - 6 - 5

5x = 3y - 11

x = (3y - 11) / 5.
