(4x-7) +x>51
4x-7+x>51
5x-7>51
5x>51+7
5x>58
x>58/5
x>11.6 = 12
Mateo can have at least 12 trading cards
Answer:
Step-by-step explanation:
When two variables say x and y are proportional let us assume y dependent variable and x independent variable
then we have y =kx
Here k is called the constant of proportionality.
Whenever x increases/decreases by 1 unit, the y value also increases/decreases by k units.
Whenever x=1, y =k
and always 
Thus we can fill up as
the constant of proportionality is always the point___(1.k)____, where k is the constant of proportionality. Additionally, you can find the constant of proportionality by finding the ratio of___y to x____, for any point on the___graph of the function.___.
It would help you to make a table because say your answer is 8 pieces is 1 minute and then the next question is how long wouls it take sam to cut 24 pieces you would use the table with you first answer and then multiple both numbers 3 times to give you your answer. Its really just a way to have more organized answers
It's can be 5×10^4
5×10^4= 5×10000=50,000
