So you would add 12 to the other side of the equation, and 9+12=21, so x=21.
Answer: 19/12 pounds or 1.583 pounds
Step-by-step explanation:
Let a pound be represented by x. So x = 1 pound.
5/6 of a pound is the same as multiplying 5/6 × x. It becomes 5/6 × x = 5x/6
3/4 of a pound is the same as multiplying 3/4 × x. It becomes 3/4 × x = 3x/4
We want to look for 5/6 of a pound + 3/4 of a pound.
It becomes
5x/6 + 3x/4
Taking lowest common multiple(LCM) of 12, it becomes
= (2×5x + 3×3x) / 12
= (10x +9x)/12
= 19x /12
Substituting x = 1 pound,
It becomes 19/12 pounds
Expressing in decimal, 19/12 = 15.83
We can also solve from the beginning in terms of decimals
5/6 pounds = 0.833 pounds
3/4pounds = 0.75 pounds
5/6 pounds + 3/4 pounds = 0.833 + 0.75 = 1.583 pounds
X = original amount
x - 1/2x - 2 = 2/5x
1/2x - 2 = 2/5x
-2 = 2/5x - 1/2x
-2 = 4/10x - 5/10x
-2 = - 1/10x
-2 / (-1/10) = x
-2 * - 10/1 = x
20 = x <=== she was originally shipped 20 suits
It’s 2x3x3x5 because 9 isn’t prime
