The two angles form a straight line and need to equal 180 when added together:
7x + 28 + 33 = 180
Simplify:
7x + 61 = 180
Subtract 61 from both sides
7x = 119
Divide both sides by 7
X = 17
Answer: B.17
Answer:
Simple random sampling survey method
Step-by-step explanation:
A simple random sampling is an unbiased survey technique Hence it will represent all the parts of the city's population.
In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process
Answer:
2x²y+(x²y-2xy²) = 3x²y-2xy²
(5xy²-x²y) +3x²y = 5xy²-2x²y
4x²y+(x²y+xy²) = 5x²y+xy²
x²y+(-2xy²-4x²y) = -3x²y-2xy²
Step-by-step explanation: there you go
