Convert 540 grams to kilograms` 0.54 kilograms, and add to the previous record
Answer:
Step-by-step explanation:
The lengths can be found by considering their ratio:
short : long = 1 : 5
The sum of the ratio units is 1+5 = 6, and the sum of the lengths is 144 inches. That means each "ratio unit" stands for (144 in)/6 = 24 inches of length.
The lengths are ...
1 : 5 = 24 in : 120 in
The pieces are 24 inches and 120 inches in length.
__
Equivalently, you can let s represent the shorter length. Then 5s is the longer one, and their total is ...
s +5s = 144
s = 144/6 = 24
5s = 5(24) = 120
The lengths are 24 inches and 120 inches.

Step-by-step explanation:
Answer:
3) ab = ba
This is called Commutative property of Multiplication.
4) 5 (3x -2) = 5*(3x) - 5*(2) = 15x -10
This is called Distributive property.
5) 1/2 (4-2x) = 2 - 2x
Applying distributive property on left side
1/2(4) - 1/2 (2x) = 2- 2x
2-x ≠ 2 - 2x
The pair of equation is not equivalent.
6) 1/2 (6x -2) = 3 - x
Applying distributive property on left side
1/2 (6x) - 1/2 (2) = 3 - x
3x - 1 ≠ 3 - x
The pair of equation is not equivalent.
7) 32y +12y = 44y
8) 12+ 3x - x - 12 = 12-12+3x -x = 2x
