Answer:
r = 13
Step-by-step explanation:
these angles are vertical and are congruent
8r + 6 = 9r - 7
6 = r - 7
13 = r
Answer:
In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match.
Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power. For example, 8xyz2 and −5xyz2 are like terms because they have the same variables and power while 3abc and 3ghi are unlike terms because they have different variables. Since the coefficient doesn't affect likeness, all
What? This isn’t really a question!
Answer:
Two.
Step-by-step explanation:
Simultaneous equation is a Finite sets of equations whose common solutions are sought.
Two solutions in the equation above is sought.
The answer is 3!
explanation; 3x10 equals 30. the difference is 27 years and 30-3=27!
