So 2.25 is 50% of the original price
let's write original price as x
50% of x = 2.25
0.5 * x = 2.25
divide both sides by 0.5
x = 4.5
The original price is 4.5
To check:
50% * (4.5) =?= 2.25
0.5 * 4.5 =?= 2.25
2.25 = 2.25
Hope this helps.
I think it’s the third one
There's a 8ft. long board and the carpenter cut off 3 1/2 and 2 1/3.
So first we need to add 3 1/2 and 2 1/3 because the carpenter cut them off the 8ft. long board.
3+2=5 because it's a whole number. 1/2+1/3= 2/6+3/6= 5/6
5 5/6
Now we subtract
8-5 5/6=
7 6/6- 5 5/6= 2 1/6ft.
2 1/6ft. is what remains of the 8ft. board.
Answer:
(3-x)/9
Step-by-step explanation:
(9-x^2)
---------------
9x+27
Factor the numerator and denominator
(3-x) (3+x)
----------------
9(x+3)
Rewriting the denominator as 3+x
(3-x) (3+x)
----------------
9(3+x)
Canceling 3+x from the numerator and denominator
(3-x)
----------------
9
Answer:
4 - 1 - 3 - 2
Step-by-step explanation:
4 - Hydrogen enters the plant as part of water.
1 - Water is broken down into oxygen and hydrogen.
3 - Hydrogen combines with carbon dioxide to form glucose.
2 - Glucose is broken down to be used by plants.
During the process of photosynthesis, water and carbondioxide combined in the presence of sunlight to give rise to glucose which is then broken down to be used by plants. This is the process by which plants manufacture their food. Water is made up of hydrogen and oxygen. The hydrogen combines with CO2 to produce sugar for the plants.
