Answer:
B. 2x-3
Step-by-step explanation:
14 and 21 have a common factor which is 7 so divide both by 7 to get 2x-3.
Answer:
The recipe calls for 19/12 or 1 7/9 cups.
Step-by-step:
In order to get this answer, we have to add all three fractions together. First, we have to find the LCM (Least Common Multiple) between the three denominators:
2: 2, 4, 6, 8, 10, 12
3: 3,6,9,12
4: 4,8,12
The LCM between these three denominators is 12.
4x3=12
2x6=12
3x4=12
You now multiply the numerator by the same number you multiplied by for the denominator in order to get 12:
3/4 becomes 9/12
1/2 becomes 6/12
1/3 becomes 4/12
We now add all the fractions together:
9/12+6/12+4/12= 19/12
We got 19/12 but the answer is an improper fraction so we turn it into a mixed number:
12x1=12 (7 remaining)
This is written as 1 7/12.
Hope this helps! :)

Answer:
no
Step-by-step explanation:
first simplify or solve the original expression ( 3(x + 11/2)-3 )
1. Parenthesis go first so do the 11/2 = 5.5 (x+5.5)
2. Distribute the 3 to the parenthesis (3x + 16.5)
3. subtract 3 from the expression (3x + 13.5)
Compare new equation with 3x + 11/2. Are they the same? (3x+13.5 vs. 3x + 11/2)
They are not the same thing.
For the first question you just need to add up all the sides. so first add all the x numbers and then add all the plain numbers.
a perimeter is the total length around the shape.
