Math pretty much has its own language. In an expression, u have to " break it apart " to make each term
one more then the product of a number and 7 decreased by 5...
" product " means multiply.....so the product of a number and 7 would be 7n.
one more then the product....(7n + 1)....." decreased" means subtract....
so ur expression is : (7n + 1) - 5
(7n + 1) - 5....when n = 6
(7(6) + 1) - 5 =
43 - 5 =
38 <==
To simplify this ration we need to divide each member of ration with same number.
We can start with 2.
18/2: 30/2 : 72/2 or
9:15:36
Now we can divide by 3 because 15 isn't divisible by 2.
we get:
3:5:12
This ration cannot be simplified further.
Answer:
$160
Step-by-step explanation:
You can set up an equation that will work for any time period, but since it is only 4 months we can do this simply too:
10 x 2 = <em>20</em>
<em>20</em> x 2 = <u>40</u>
<u>40</u> x 2 = 80
80 x 2 = 160
