So, the percent it grew each year (assuming it grew a consatnt amount each year) is 17.4/13
why?
13/13 = 1 year. so we do 17.4/13 to see how much it grew eahc year..
so the answer rounded off 3 decimal places is 1.338
Step-by-step explanation:
Answer:
a=2
Step-by-step explanation:
12a - 5 = 4a + 11
Subtract 4a from each side
12a-4a - 5 = 4a-4a + 11
8a -5 = 11
Add 5 to each side
8a -5+5 = 11+5
8a = 16
8a/8 = 16/8
a =2
The answer is 2, yous add all of them up and divide by how many there are.
They are all pretty easy all you do is multiply the cost by the amount of things you buy. For example number 4 your variables are cost (c) and songs (s). Your equation is c•s so $0.99 • s. 50 songs would be .99 • 50 which is $49.50
By replacing you get:
5*7-2*11+3*(-1) = 35-22-3= 10
so the answer is 10.
