Answer:
5.34 pages/h
Step-by-step explanation:
4/45 = p/60
p ≈ 5.34
3 over 5 x minus 15 = 6 over 5 x plus 12
3/5x - 15 = 6/5x +12
-3/5x+3/5x-15=6/5x-3/5x+12 subtraction property
-15=3/5x+12 simplified
-12-15=3/5x+12-12 subtraction property
-27=3/5x simplified
(5/3)(-27)=3/5 (5/3)x multiplicative inverse
-45=x
F(x)=2x+3. easy as that, just replace y with f(x)
