you divide 30/1 by 2/5. to do that you cross multiply. So 30x5 and 2x1. And get 150/2. Then you simplify.
Hope this helps!(:
Rewrite the system of equations in matrix form.
This system has a unique solution 
so long as the inverse of the coefficient matrix 
exists. This is the case if the determinant is not zero.
We have
so the inverse, and hence a unique solution to the system of equations, exists as long as m ≠ -4.
Answer:
1500 dollars
Step-by-step explanation:
annual means yearly and we want to find how much it will cost for 5 months
First thing we want to do is find how much it cost every month and to do that we divide 3600 by 12
3600/12=12 so it cost 300 dollars monthly
then we just multiply that by 5
5x300=1500 so it cost 1500 dollars for 5 months
Answer:
D) 15
Step-by-step explanation:
The sum of the interior angles of a polygon is given by
We have that, the sum of the interior angles of a polygon is
26 right angles. We want to find n, the number of sides.
We substitute into the formula to get:
Divide through by 90
Divide through by 2
X=8 & z=66
because vertical angles are congruent
