dylan has x pennies and y nickels in his piggy bank. his brother told him to take out at least 6 coins from his piggy bank.

which inequality models this situation?

a: 0.01x + 0.05y > 6

b: x + y > 6

c: x + y ≥ 6

d: 0.01x + 0.05y ≥ 6

I'm pretty sure it is D. This is because there are x pennies, 0.01 is how much a penny is, and y nickels, with 0.05 as the amount of 1 nickel. Dylan's brother told him to take out AT LEAST 6 coins from the piggy bank, and that sign at the end (between 0.05y and 6, i dont have the sign on my keyboard) means at least. So, I think its D.

I’ll you if you answer my questions!

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the value of x is equal to 0.
