2x + 3y = 9
x + 5y = 8....multiply by -2
----------------
2x + 3y = 9
-2x - 10y = -16 (result of multiplying by -2)
---------------add
-7y = - 7
y = -7/-7
y = 1
x + 5y = 8
x + 5(1) = 8
x + 5 = 8
x = 8 - 5
x = 3
solution is (3,1)
Question 1 demonstrates the Commutative Property.
Ill show you step by step.
This is what the equation should look like
Y=Initial value(1+/- Increasing or Decreasing value)^2 Which stands for time

So you need to do 1.0525 to the 2nd power Which equals 1.10775625
So now you need to do 15,000(1.10775625)

Which equals <span>16616 rounding to the nearest Ones
16616.3 rounding to the nearest tenth</span>
Angles in straight line add to 180 degrees
180-142=38
180-133=47
180-38-47=95
180-95=85 degrees
B
Answer:
Step-by-step explanation:
number of weeks=103.50/5=20.7 bi-weeks
so she needs 21 bi-weeks or 42 weeks
