Hello!
You can break this down
12 times the sum of 3 and c
This can be written as 12(3 + c)
is greater than 27
12( 3 + c) > 27
This can be simplified to 36 + 12c > 27
The answer is 12(3 + c) > 27 or 36 + 12c > 27
Hope this helps!
Ok so its 8 `1&8 2&7 3&6 4&5 and then all of those numbers reversed
18 27 36 45 and 81 72 63 54
For this one, instead of breaking it down into 3 shapes we can simply subtract the missing square area from the total enclosing area...
15*8-4*4
120-16
104 cm^2
<span>We have the yearly cost in dollars y at a video game arcade based on total game tokens purchased

. So we know that:

<span>
</span><span>
Then we can study this problem by using the graph in the figure below. We know that if there's no any purchase, the yearly cost for a
member will be $60 and for a
nonmember there will not be any cost. From this, we can affirm that the cost of membership is equal to $60.
On the other hand, both members and nonmembers will pay the same price on the total game tokens purchased, this is true because of the same slope that members and nonmembers have in the equations.</span>
