We are asked to simplify the expression \large\pmb{7x^2-x^2}.

\triangle~\fbox{\bf{KEY:}}

  • Combine like terms! :)

That's exactly what we need to do - combine like terms.

So, we subtract:

\star~\large\pmb{7x^2-x^2}

Which gives us:

\star~\large\pmb{6x^2}

Hope it helps you out! :D

Francis went to the sporting goods store and spent $75.15 on 6 items.
MArishka [77]

Answer:

$6.03

Step-by-step explanation:

The question is asking us how much each pair of socks cost. With the information we are given, we know that there are 5 pairs and that they all cost the same amount. If the total were just the 5 socks, we could easily divide the total by 5 to get the price of each pair but that's not the case. The soccer ball is included in the final cost. To overcome this, we just have to subtract the soccer ball's cost ($45) from the total.

So we subtract $45 from $75.15, giving us $30.15, the total amount of all the socks. However we need to find out how much each pair costs and there are 5 of them, so we divide 30.15 by 5. This gives us the answer, $6.03.

Each pair of socks cost $6.03.

Simpler Explanation:

  • $75.15 - $45 = $30.15
  • $30.15 / 5 = $6.03

The answer is $6.03
