2x + 18y = 36
Solving
2x + 18y = 36
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-18y' to each side of the equation.
2x + 18y + -18y = 36 + -18y
Combine like terms: 18y + -18y = 0
2x + 0 = 36 + -18y
2x = 36 + -18y
Divide each side by '2'.
x = 18 + -9y
Simplifying
x = 18 + -9y</span>
Answer:
The value of the given expression is

Step by step Explanation:
Given that 
To find the value of 
Let us find the value of the expression :
( by using the formula
here A=2A)


(using
here A=2A)
(using
here A=2A)




( using
here A=2A )
(since tanA=a given )
Therefore 
Answer: The student’s values are accurate as well as precise.
Explanation:
Precision refers to the closeness of two or more measurements to each other.
For Example: If you weigh a given substance three times and you get same value each time. Then the measurement is very precise.
Accuracy refers to the closeness of a measured value to a standard or known value.
For Example: If the mass of a substance is 50 kg and one person weighed 49 kg and another person weighed 48 kg. Then, the weight measured by first person is more accurate.
Given: Mass = 5.000 g
Mass weighed by A has values 4.891 g , 4.901 g and 4.890. Thus the average value is
Thus as the measured value is close to the true value, the student’s values are accurate and as the values are close to each other, the measurement is precise.
There are 37 balloons total and there are 7 orange balloons. Therefore, the probability is 7/37.
We have been given two functions
and
