Short answer 2 items for 25 cents.
To solve this, all you have to do is divide money by the number of items.

You put it into your calculator in exactly the same order.
Money
÷
Number of items
=
So in this particular question
1 dollars / 5 items = 0.20 dollars / item
0.85 dollars / 4 items = 0.2125 cents
0.25 dollars / 2 items = 0.125
1.10 dollars / 6 items = 0.18333
Which gives you the best value for your money?
.25 spent on 20 items. The order is determined by the larger the amount on the right of the equal sign, the more expensive the item.
18:4,18/4,18 to 4
18/4 equals 4 1/2
X = sandwich, y = soda
x + 2y = 5.5
x = y +1
Solve the system of equations and you have: y = 1.5 and x = 2.5
30.8
you take 25^2 + 18^2 and find the square root of that which is 30.8 for this problem.
please give me brainliest :)
Answer:
Step-by-step explanation:
(x+3)(x-3)
x squared and -9 are both square numbers.
the square root of x^2 is x
the square root of -9 is 3. so you just need to write (x+3)(x-3)
you can check by expanding the brackets and the middle x terms should cancel out
