F=the number of fish she has at the end of three months
X=the number of months
F=3x(2)
F=3(3)•2
F=9•2
F=18
Just add them together. For example if you have 4x and 7x you would just do 4x+7x and get 11x. You can only add them because they are like terms, meaning that they share a variable.
Step-by-step explanation:
If two lines cross each other the angles opposite of each other are the same. So left=right and top=bottom. Knowing this the bottom angle must be 120°. if 3x=120° then x=40°
The answer is 21%. you can find this by dividing 363 by 300 to get 121. This tells you 363 is 121% of 300. Therefore, making the area of the room 363 is <em>increasing </em>the area by 21 percent.
Answer: 25%
Step-by-step explanation:
Original price of chocolate = $48
Price taken off for Tom = $12
i.e $12 out of $48 means Tom bought the chocolate $32
Hence, percent discount = (Price taken off/Original price) x 100%
= (12/48) x 100%
= 0.25 x 100%
= 25%
Thus, the percentage discount on the chocolate is 25%
