You are right on the question
Answer:
d(4)=?
where
d= distance
t= hours
In this Linear function given by the law d(t) = 12t +20 and the graph below. To find the d(4), means to find out how many miles she cycled in the instant 4 hours.
By this function, after a break , the instant t=0, she had already cycled 20 miles.
Let's calculate
d(4) = 12(4) +20
d(4) =48+20
d(4)= 68 miles
Step-by-step explanation:
The answer to the question is b
100. Percent means out of hundred, so one percent means one out of a hundred, two percent means two out of a hundred, etc.
1.n represents the number of tickets she bought.
2.27.75n represents the total cost of n tickets
3.Without the handling fee Olga paid 138.75
4.To get 27.75n by itself on one side of the equation you can move 5.5 from the left to right of the equation
<u>Step-by-step explanation</u>
n is the total number of tickets Olga bought.
27.75n represents the total cost of n tickets.It is given in the question that one ticket costs $27.75 and thus n number of tickets will cost $27.75 n.
The handling fee is 5.5
27.75n+5.5=144.25
27.75n=144.25-5.5=138.75
without the handling fee Olga will pay $138.75
