Since 1/4 is equal to 0.25 than you would do 5,400 times 0.25 and get the answer of 13,500.0. So the race car weighs 13,500 pounds.
For the 2nd equation, you need solve for y to get it by itself so once thats done you get y=9x+27 but since the x values (also the slope) aren't equal, they can't be parallel
Answer:
x = 11
Step-by-step explanation:
x + (x - 2) = 20
2x - 2 = 20
2x - 2 + 2 = 22 + 2
2x = 22
x = 11
