Ali has 13 CD's
Here's how I got my answer:
Step 1: Simplify
to 50. Which leaves us with 
Step 2: Simplify
to 5. Which leaves us with
.
Step 3: Simplify
, to get your answer, 13.
Jacinda: d = 10 * t ( a rate: 10 miles per hour )
Raj : d = 1.5 + 4.5 * t
Jacinda will catch up with Raj when:
10 t = 1.5 + 4.5 t
10 t - 4.5 t = 1.5
5.5 t = 1.5
t = 1.5 : 5.5 = 0.27 hours = 16.2 min = 16 min 12 seconds
I am sorry I am not in that level yet
well the formula i came up with is the t=time d= drove and r=rate
youre trying to find the Time, so therefore the beginning of the equation is t= ?? so theres a lil hint :)
Answer:
ft
Step-by-step explanation:
Given parameters:
number of inches of growth = 5inches
time duration =
month
Unknown:
Number of feet that can grow in one month = ?
Solution:
To find the rate;
Rate of growth =
Insert parameters and solve;
Rate of growth =
Rate of growth = 5inches x 
=
inches/month
Now,
Number of feet in one month:
= rate of growth x 1 month
=
inches/month x 1 month
=
inches
Since; 5inches =
feet
inches will give
ft
=
ft
