Answer:
4.5
Step-by-step explanation:
First we need to turn the ratio of 1 : 3 into a fraction
1:3 = 1/3
Next we need to square that fraction
1 x 1 = 1
3 x 3 = 9
Then we turn those numbers into a fraction
1/9
We turn the .5 into a fraction
.5/x
And cross multiply both fraction by each other
1/9 x .5/x
1 x X = X
9 x .5 = 4.5
So
4.5 = X
The greatest common factor is 
Explanation:
The given expression is 
We need to determine the greatest common factor of the given expression.
The greatest common factor of two numbers is the largest number of the two numbers that divides them both.
Hence, from the given expression, let us common out the highest factor that divides the two numbers.
Thus, we have,

Thus, the largest number that divides both the terms is 
Hence, the greatest common factor of the given expression is 
Answer:
so wouldnt it just be 2250 but i have no clue ur question is confusing
Step-by-step explanation:
Answer:
a≤3
Step-by-step explanation:
3a-4≤5
Move constant to the right hand side and change its sign
3a≤5+4
Add the numbers
3a≤9
Divide both sides of th inequality by 3
a≤3
