To reduce down a fraction you can try to find factors that go in both the numerator (top # of fraction) and denominator (bottom #)
So, for 6/9, 3 goes in both of them. When you divide each number by 3 you get:
2/3
There is no solution
Distributive property
3/4 x 8t - 12 x 3/4=6 x t - 1 x 6
6t - 9=6t - 6
The 6t being on both sides makes the answer. No solution.
Answer:
<h2><em><u>
B or the second one</u></em></h2>
Step-by-step explanation:
This is because you have the equation of 2(2/5x + 2).
When you simplify it you have to first do the parenthesis.
So, 2 * 2/5 = 4/5. This is because 2/1 *2/5 is 4/5.
Then you have to do 2*2. This is equal to 4.
Put them together. So it will be.
<h2><u><em>
4/5x + 4.</em></u></h2>
Answer:
The population density for the village and the estate together is 112.5 people per square kilometer.
Step-by-step explanation:
The statement is incorrectly written. Correct form is described below:
<em>A village has an area of 6 square kilometers and a population density of 600 people per square kilometer. An estate stituated next to the village has a population of 800 and a population density of 400 people per square kilometer. Work out the population density, in people per square kilometer, for the village and the state together. </em>
Dimensionally speaking, the population density of the village and the estate together (
), measured in people per square kilometer, is defined by this expression:
(1)
Where:
,
- Population of the village and the estate, measured in people.
,
- Area of the village and the estate, measured in square kilometers.
First, we find the population of the village:


Then, we determine the area of the estate:


If we know that
,
,
and
, then the population density of the village and the estate together is:


The population density for the village and the estate together is 112.5 people per square kilometer.
Alright so A is 6/10 * 5/9 = 1/3
B is 4/10 * 7/9 = 2/15
C is 6/10 * 4/9 = 4/15
I hope this helps
