It is given in the question that
The measure of one angle is 15 less than half the measurement of its supplement.
Let the measurement of supplement angle is x degree.
So the measurement of the other angle is
And the sum of the measurement of supplementary angles is 180.
Multiplying both sides by 2
So one angle is of measurement 130 degree and the other angle is of measurement 50 degree.
Answer: (4,3)
Step-by-step explanation:
1. In this method you must solve one of the equation for one of the variables and substitute it into the other equation to find the other variable. Then, substitute the value of that variable into one of the original equation to obtain the value of the other one.
2 You have that:
3. Then, you can substitute it into the other equation and solve for x:
4. Now you can obtain y:
5. The answer is:
(4,3)
Answer:
D. .
Step-by-step explanation:
Given:
We need to reduce by
Solution:
To reduce the equation means we need to subtract the one equation from other.
First we will arrange the equation n proper format we get;
⇒ equation 1
Also Arranging other equation we get;
⇒ equation 2
Now we will subtract equation 2 from equation 1 we get;
Now Applying distributive property for the sign we get;
Now Arranging the like terms we get;
Hence the reduce form of the given equation is .
