9c/5+32=f

(9c+160)/5=f

9c+160=5f

9c=5f-160

c=(5f-160)/9

c(77)=(5(77)-160)/9

c(77)=25°

9/5c + 32 = f
9/5c = f - 32
c = 5/9(f - 32) <==

when f = 77
c = 5/9(77 - 32)
c = 5/9(45)
c = 225/9
c = 25 <==

What is 2/3x=2y+6 in ax+by=c form?
kifflom [539]

Answer:

2x - 6y = 18

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

\frac{2}{3} x = 2y + 6

Multiply through by 3 to clear the fraction

2x = 6y + 18 ( subtract 6y from both sides )

2x - 6y = 18 ← in standard form
