8.5b.
7a= 5a +3b
-5a -5a
2a = 3b
/2
a= 1.5b
Solve by substitution and you get;
8.5b=8.5b
Because of the lack of constants in the equation there isn't a definite answer.
We need to move the decimal so that there is only one whole number.
375,000.
To do that, we move to the left 5 spaces
3.75000
Now since we moved 5 spaces to the left it would be 3.75 * 10^5
Answer:
The simplify form of the provided expression is:
Step-by-step explanation:
Consider the provided expression.

Now simplify the above expression as shown below:

as 16/8 = 2
Now again simplify the above expression.
as 2/6 = 1/3
Now, multiply the whole expression with 3.
Hence, the simplify form of the provided expression is:
5? Did you mean to insert a picture

so, as you can see, the "common difference" is -5, namely to get the next term we simply "add" -5 to the current one, and we know the first term is 12, ok, so,
