Answer:
x=-12
Step-by-step explanation:
Start by getting all of the x values on one side and other to the other.
1/3x-3/4x=1+4
Now simplify. Because 1/3 and 3/4 do not have the same denominator, find the least common factor between 3 and 4 (which is 12) and make the fractions have denominators of 12.
4/12x-9/12x=5
-5/12x=5
x=5*(12/-5)=60/-5=-12
x=-12
Option ( C ) is the correct answer.
Answer:
44.3 would be the correct answer if I looked at it correctly
Answer: 20;
w - width
3w - 1 - length
54 in - perimeter
w + w + (3w - 1) + (3w - 1) = 8w - 2 - perimeter
The equation:
8w - 2 = 54 add 2 to both sides
8w = 56 divide both sides by 8
w = 7
3w - 1 = 3(7) - 1 = 21 - 1 = 20
Answer: The length = 20 in.
