Answer:
The original price of a skateboard is $64
Step-by-step explanation:
Let
x ----> the original price of a skateboard
y ----> the new price of a skateboard
we know that
The linear equation that represent this problem is equal to
y=x-15 ----> equation A
y=49 ---> equation B
substitute equation B in equation A and solve for x
49=x-15
Adds 15 both sides
49+15=x
64=x
Rewrite
x=$64

Answer:
12x² - 9x
Step-by-step explanation:
Simplify the expression. Distribute 3x to all terms within the parenthesis. Multiply:
3x * 4x = 12x²
3x * -3 = -9x
12x² - 9x is your answer.

X - 19 + x + 65 = 180. 180° equals a line, and therefore a linear pair.
Then, solve your equation. 2x = 134. So, x = 67°. 67 - 19 = 48. 180 - 48 = 132. The answer is A.
