Answer:
360 screws
Step-by-step explanation:
First we need to determine how many screws she needs for the 2 decks
We will determine the number of screws for 1 deck
1 deck uses 25 pieces of wood
25 pieces of wood * 8 screws/ piece of wood = 200
200 screws per deck
She is building 2 decks
2 * 200 = 400
400 screws for the 2 decks
She has 40 screws
400 screws she needs - 40 screws she has = 360 screws she still needs
Answer:
equation form: 12 + 2x = 18
x = 3
lets check the work see if its true
12 + 2(3) = 18
12 + 6 = 18
It Checks!
therefore your answer is 3. He can get 3 different toppings

Replace 'x' with the number corresponding to the side of the table.
Ex. f(-2)=2(-2)-5
Answer:
Scientist B
Step-by-step explanation:
1 kg = 2.2 lbs
1L = 2.11 pints
So let's convert Scientist B's data.
3.0lbs salt = 3.0/2.2 = 1.36kg
6 pints water = 6/2.11 = 2.84L water
Scientist A
1kg salt
3.0L water
We now figure out the concentration of salt in water.
Scientist A Scientist B
1kg/3.0L = .33kg/L 1.36kg/2.84L = .48kg/L
So scientist B had a more concentrated solution.
