92 is the answer :> also happy v-day!
Answer:26
Step-by-step explanation:
Y=1.25^x-2/5-10
Take log of both sides
So Y+10=1.25^x-2/5
So log to base 10 of the two sides of the equation is
Log(Y+10)=X-2/5log1.25.
To make X the subject, divide both sides by log1.25.
Log(Y+10)/log1.25=X-2/5.
Recall that Y was given to be 115
It becomes log(115 +10)/Log1.25=x-0.4
21.64=x-0.4
X=25.6
What are we solving for the value of a b and c or like how do u want this solved ?
Answer:
16.7 would be the bigger
Step-by-step explanation:
Hope this helps :)
Sorry if im wrong :(
Let x = the number of hours you rented the boat
$140 = $20x + $60.
Subtract 60 from both sides
$80 = $20x
Divide each side by 20.
4 = x.
You rented the boat for 4 hours
