5 : 3 = 30:x where x = number of south american butterflies
5/3 = 30 / x
5x = 90
x = 18
there are 18 south american butterflies in the park
What is your question I will answer it if I can
Answer:
85/1
Step-by-step explanation:
because both numbers are divisible by 16
Answer:
1.95
Step-by-step explanation:
hello :
ln (x + 6) – ln (2x – 1) = 1 ...(*)
this expression exist : 2x-1 > 0 and x+6 > 0 means : x> 1/2 and x > -6
hence for : x> 1/2 (*) equivalent to ln((x+6)/(2x-1))= lne.......(1=lne)
(x+6)/(2x-1) = e
x+6 = e(2x-1) means : x+6 = 2ex-e
-x+2ex = e+6
x(2e-1) = e+6
x = (e+6)/(2e-1) =(2.73+6)/(2(2.73)-1) =8.73/4.46 =1.95
