Answer:
53d
Step-by-step explanation:
Numerical form is an actual number as opposed to a word.
"Seven" is not numerical form.
"7" is numerical form.
It would be a > 12, move all terms to one side and then solve for x. make sure if you divide then you flip the term
Think about it this way, what is 5x3??? 15 right. Ok then what is 5x30???? 150. So the store should sell each soccer ball for $5 each:)
Answer:

3)The example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7. Plug in the x value in to the first equation to find out the y value. y = 2 - 3(-5/7) becomes 2 + 15/7, which is 29/7.
