Answer:
C) 9n - 3
Step-by-step explanation:
<em>make an expression</em>
2n - 1 - (-7n + 2)
<em>open the parenthesis</em>
2n - 1 + 7n - 2
<em>combine like terms</em>
9n - 3
Answer:
The number is 2.
Step-by-step explanation:
Let x represent the missing number and write an equation based on the information given, and solve for x
9x + 6 = 3 * 8
Simplify
9x + 6 = 24
Subtract 6 from both sides
9x + 6 - 6 = 24 - 6
9x = 18
Divide both sides by 9 to isolate x, and solve
9x ÷ 9 = 18 ÷ 9
x = 2

Answer:
90 - 63 = 27 degree
Step-by-step explanation:
Answer:
First box: A straight line measures 180 degrees
Second box: Alternate interior angles theorem
Step-by-step explanation:
All lines are straight, and therefore measure 180 degrees
You can see that the red line is parallel to the line with angles 2 and 3. Alternate interior angles are two interior angles which lie on different parallel lines and on opposite sides of a transversal. Which justifies step 2
