Step-by-step explanation:
Answer: B) 6x - 6 = 15x + 15
Step-by-step explanation:
To find our answer, we need to first work out each equation.
A) 6x - 15 = 6x + 15
First, cancel out the equal terms.
6x - 6x - 15 = 15
-15 = 15
This statement is false.
B) 6x - 6 = 15x + 15
-9x = 21
x = -7/3
<u>This statement has one solution. </u>
C) 6x - 6 = 6x + 15
-6 = 15
This statement is false.
D) 6x + 15= 6x + 15
15 = 15
This statement has infine solutions.
Answer:
<em>102°</em>
Step-by-step explanation:
(3x - 12)° + (2x + 2)° = 180°
5x - 10 = 180 ⇒ x = 38
m∠A = (3x - 12)°
<em>m∠A</em> = (3×38 - 12)° = <em>102°</em>
