Answer:
5
Step-by-step explanation:
take your price and subtract the monthly price
115-40=75
now you have the price of all your extra devices summed up
75÷15=5 extra devices
96% is the answer 100%/x%=125/120
(100/x)*x=(125/120)*x - we multiply both sides of the equation by x
100=1.04166666667*x - we divide both sides of the equation by (1.04166666667) to get x
100/1.04166666667=x
96=x
x=96
Answer:
Step-by-step explanation:
Step 1: Solve one of the equations for one of the variables.
Step 2: Substitute that equation into the other equation, and solve for x.
Step 3: Substitute x values into one of the original equations, and solve for y.
Answer:
22.05
Step-by-step explanation:
21x150%=31.5
31.5×30%=9.45
31.5-9.45=22.05
4 and 8 are corresponding angles.
The easiest way to tell is to look at the two groupings: 1, 2, 3, 4 and 5, 6, 7, 8. 4 and 8 are in the same position in both groupings (bottom right corner). This makes them corresponding.
Adjacent angles would have a common side and vertex. This would be like 4 and 2 or 1 and 3 or 5 and 7 or 8 and 6.
Alternate interior angles would be opposite angles inside the parallel lines. This would be like 4 and 5 or 3 and 6.
Alternate exterior angles would be opposite angles outside the parallel lines. This would be like 2 and 7 or 8 and 1.
