Step-by-step explanation:
Answer:
Step-by-step explanation:
The answer is -6/-1 or -6 is because you simply -72/-12 you get -6 you can check that they are equivalent by cross multiplying.
Answer:
1) Adding
2) x = 1.5 y = 8
Step-by-step explanation:
1. Which would be a more helpful for solving the system: adding the two equations or subtracting one from the other?
Adding.
Would eliminate the y variable
2.solve the system without graphing, show your reasoning
After adding the equations
8x = 12
Divide both sides by 12
x = 1.5
Substitute into the first equation
2(1.5) + (1/2)y = 7
3 + (1/2)y = 7
(1/2)y = 4
y = 8

Answer:</h2>
144 cm squared
<h2>
Step-by-step explanation:</h2>
The steps are same as for the calculation of area of the octagon I solved for you earlier. That is why I will post here only calculations and not the actual steps.
360/10=36 degrees
36/2=18 degrees
sin(18)=x/7
x= 2.1631 cm
Cos(18)=y/7
y=6.6573
y*x= 14.4006
14.4006*10=144 cm squared
