Answer:
30 CDs and 10 Videos were sold.
Step-by-step explanation:
Given that a used book store also started selling used CDs and videos. In the first week, the store sold 40 used CDs and videos, at 4.00 per CD and 6.00 per video.
The sales for both CDs and videos totaled to 180.00.
Let CDs be x and Videos be y
Then we have x+y =3040
and 4x+6y = 180
Two simultaneous equations in two variables and can be solved by elimination method
multiply I equation by 4 and subtract from II.
2y = 20
y =10
x = 30
30 CDs and 10 Videos were sold.
If you would like to solve 9 5/9 - 6 5/6, you can calculate this using the following steps:
9 5/9 - 6 5/6 = 86/9 - 41/6 = 516/54 - 369/54 = (516 - 369) / 54 = 147/54 = 49/18 = 2 13/18
The correct result would be 2 13/18.
Answer:
You would also need to know for how many hours each day would you be working.
145 pages because 145 would round up to 150 but anything below 145 would round to 140
Answer:
Step-by-step explanation:
Exponential functions grow at the fastest rate because the function increase or decrease in a power form.
for example, "2 raised x "means that when ever the power increase the number gets large and the same for decrements.
example: when x=1 it becomes 2
x=2 4
x=3 8
.
.
x=n 2∧n which a very big number.
In the same case it decreases dramatically if the power is negative or the number is improper fraction with positive number exponent; like (3/4)∧x,2∧-x when x is positive real number.
The similarities of both trend is that the change is the same both decrease or increase in similar scenario.
the difference is already known that one goes up with out bound but the one which decays goes down ward both with limitation and in unlimited cases.
