Hello! So, the sum of the angles of a triangle is 180 degrees. There’s already an angle that is 60 degrees. So, there are 120 degrees left to be found. You set this formula up as 3y = 120. Divide each side by 3 to isolate the y. When you solve that, you should get y = 40.
2y = 80 degrees
y = 40 degrees
Given:
To find:
The steps to prove the given statement by using the properties of multiplication.
Solution:
We have,
Taking left hand side, we get
(Associative property of multiplication)
Hence proved.
Let X be the variable used to represent the expression of the total number of books that Mario has read.
We used 4X to represent "four times the number of books". Then we add -2 to interpret the words "for two less than".
Therefore, we have an expression of 4X-2 for the total number of books that Mario has read.
6=S
therefore, to find one you must divide both sides by 6
the answer should be = 1=S/6
