Answer:
72°
Step-by-step explanation:
Given
Zy = 108°
Zx = ?
We know
Zx + Zy = 180° {being supplementary angles }
Zx + 108° = 180°
Zx = 180° - 108°
Zx = 72°

Step 1: Given
Step 2: Distributive Property
Step 3: Addition Property of Equality
Step 4: Division Property of Equality
Step-by-step explanation:
We need to match the reason with the correct step in the equation.
Equation:
Given:
![2x = -4(x-3)](https://tex.z-dn.net/?f=2x%20%3D%20-4%28x-3%29)
Applying Distributive property a(b+c)=ab+ac
![2x=-4x+12](https://tex.z-dn.net/?f=2x%3D-4x%2B12)
Now, Applying addition property of equality:
Adding +4x on both sides
![2x+4x=-4x+12+4x\\6x=12](https://tex.z-dn.net/?f=2x%2B4x%3D-4x%2B12%2B4x%5C%5C6x%3D12)
Now, Applying Division property of Equality:
Divide both sides by 6:
![\frac{6x}{6}=\frac{12}{6}\\x=2](https://tex.z-dn.net/?f=%5Cfrac%7B6x%7D%7B6%7D%3D%5Cfrac%7B12%7D%7B6%7D%5C%5Cx%3D2)
So, Answer will be:
Step 1: Given
Step 2: Distributive Property
Step 3: Addition Property of Equality
Step 4: Division Property of Equality

Answer:
≈ 58
Step-by-step explanation:
Estimation usually means you want an answer good to one or maybe two significant figures. That usually means you want to round the numbers involved to one or two significant figures.
Doing that here transforms the problem to 180/3 = 60, an answer with one significant figure.
You can improve the estimate a bit by recognizing that it is a little high (the numerator is higher than 175.32, but the denominator is the same). Since the numerator is high by about 5, the estimate is high by about 5/3 or a little less than 2. A closer estimate will be 60 - 2 = 58.
_____
The degree to which you refine the estimate will depend on the error requirements you have. Certainly an estimate of 60 is within 10% of the true value, so is "close enough" for many purposes.
Answer:
m = cost of one pencil
Step-by-step explanation:
The total cost of the pencil purchase (c) is the number of pencils (p) multiplied by their cost (m).
m represents the cost of one pencil
Decimal places are the spaces present after a decimal, denoted by the . in a number. This means, if I had 1.2 the 2 is in the first decimal place. In 3.1415 , the 5 is in the 4th decimal place. It is also commonly called, in respective order, the tenths place, the hundreds place, the thousandths place, and so on. For example, in 1.432 the 4 is in the tenths place, the 3 is in the hundredths place, and the 2 is in the thousandths place.
