Answer:
9
Step-by-step explanation:
All you have to do is follow this order while working a problem!
Example 1:
If a = 4 and b = 5, what is ab – 2b?
Since there are no parentheses or exponents,
you first plus in the values for a and b and multiply those together.
(4 ´ 5) You get 20.
Then, you multiply 2b or (2 ´ 5 )which gives you 10.
Last, you subtract the second answer from the first (20 -10),
which gives you 10!
Example 2:
Evaluate 6x / 4 when x = 6.
Because multiplication and division are equal in the order of operations, you solve the problem by reading it from left to right like one would read a book.
6 x 6 = 36.
You then divide that number by 4.
The correct answer is 9.

Answer:
1. X=35 degrees obtuse
2 x=25 degrees right
Step-by-step explanation:
Background info:
The measures of the angels of every triangle is 180 degrees
So x equals 180 minus the other angles combined
1. X=180-(40+105)
X=180-145
X=35 degrees
2.
x=180-(90+65)
x=180-155
x=25 degrees
Answer:
(6,-3) should work but there are infinite answers
Step-by-step explanation:
No, if two lines are parallel then they will have NO solutions, because they DO NOT intersect. Parallel lines have the same slope and different y-intercepts, therefore making them not intersect.
