1. A (x²-4y)³
2. ?=5
3. (x+3)(3y-5)
4. (4y+7)(5x-1)
Answer:
90
Step-by-step explanation:
because there are 5 time as many candies with nuts as candies without nuts and there is 18 so it will be 18×5=90
Answer:
Step-by-step explanation:
1) 30 : 100 = x : 299
x = (30 x 299)/100
x = 89,70 $
2) 299 - 89,70 = 209,30 $
3) 5 : 100 = x : 209,30
x = 10,465 $
209,30 + 10,465 = 219,77 $
If you square 3, you get 9, and if you "take the square root of 9", you get 3
Answer:
C(x) = 5x + 20 (for members)
C(x) = 3.5x (for non-members)
Step-by-step explanation:
Cost of membership = $20
Price of a game per month = $5
So, the linear equation to compute the total cost for a member can be computed by:
C(x) = 5x + 20
where x is the number of games per month
On the other hand, non-members can get one more game per month for $7 which means they get 2 games for $7. The price for a single game is $7/2 = $3.5 a month.
The linear equation to compute the total cost for a non-member is:
C(x) = 3.5x
where x is the number of games per month.
The following system of equations can be used to decide whether to become a member or not, by substituting the number of games in place of x and finding out the total cost.
C(x) = 5x + 20 (for members)
C(x) = 3.5x (for non-members)
