Answer: 7x squared + 10y
Step-by-step explanation:
A decimal in the wrong place can change the value of a number completely for example
0.5 can be converted to 50 cents or 1/2 but if you change the decimal 0.05 converts to 5% or 1/20.
To solve for the answer of the question above, let x be the number of words on the list. As stated above, 2/3 of this is the number of words Martina needs to memorize which is 12. This may be expressed as,
(2/3)(x) = 12
Solving for x in the equation gives an answer of 18. Therefore, there are 18 words on the list.
