Answer:
q=45
Step-by-step explanation:
To do this we have to isolate q.
q is being divided by 3, so to reverse that we have to multiply it by 3.
However, in an equation, what you do to one side, you must do to the other. This is so the equation stays equal.
15=q/3
That said, what we can do is multiply the entire equation by 3.
45=q
So the solution to the equation is 45.
Yes, because you can multiply $3 by 3 to get $9 and 6 muffins by 3 to get 9 muffins.
Answer:
A. $22,500
Step-by-step explanation:
10% = 10/100 = 1/10
To divide a decimal number by 10, move the decimal point one place to the left (remove a zero):
$225000./10 = $22500.0 = $22500
First of all, you can use
and the equation becomes
Now, from the known identity
we can half all the angles and we get
So, the equation has become
So, everything comes down to solve
The associated equation
has roots
So, we want one of the following
Solve for the associated angles and you're done
