Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient.
Step 2: Subtract the second equation from the first.
Step 3: Solve this new equation for y.
Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.
Step-by-step explanation:
1. Multiply 18.5 by 6.
18.5 x 6 = 111
2. Subtract 129.25 by 111.
129.25 - 111 = 18.25
Therefore, the answer is A. 18.25
Answer:
Step-by-step explanation:
The diagram is given to you below. I could not change <C so that it was theta. So C = theta.
So C is the reference angle. Call it theta when you think of it. The diagram shows you how cos(C) must be set up.
The adjacent side is 7
The hypotenuse is 18
theta = C = cos-1(7/18) = 67.11
To the nearest degree 67.11 = 67

the number not located between √9/3 and 2π on the number line is π/9 (option C)
Explanation:
We need to find the numbers between √9/3 and 2π
(√9)/3 = 3/3 = 1
using π as 3.14
2π = 2(3.14) = 6.28
Now we need to check the options for numbers that do not fall between 1 and 6.28:
a) π = 3.14
This number falls between 1 and 6.28
b) √9 = 3
This number falls between 1 and 6.28
c) π/9 = 3.14/9 = 0.35 (approximately)
This number doesnot fall between 1 and 6.28
d) π²/9 = (3.14)²/9 = 1.10 (approximately)
This number falls between 1 and 6.28
Hence, the number not located between √9/3 and 2π on the number line is π/9 (option C)
