Do the ratios 4/2 and 10/5 form a proportion? Yes or no
1 answer:
Answer:
These are both 20 so that means that this is proportional, yes.
Step-by-step explanation:
Hi.
To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.
Here is how we do this.
So basically what we are doing is multiplying across in a diagonal direction.
Diagonal meaning like a slash / .
So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.
Do the same for the 2 and the 10.
So we have to multiply :
4 x 5
2 x 10
=
20
These are both 20 so that means that this is proportional, yes.
Hope this helps.

For this case we must indicate the solution set of the given inequalities:
Subtracting 14 from both sides of the inequality we have:
Dividing by 6 on both sides of the inequality:
We multiply by -1 on both sides, taking into account that the sense of inequality changes:
Thus, the solution is given by all values of x greater than 7.
On the other hand we have:
Subtracting 15 from both sides of the inequality we have:
Dividing between 9 on both sides of the inequality we have:
Thus, the solution is given by all values of x less than -3.
Finally, the solution set is:
(-∞, - 3) U (7,∞)
Answer:
(-∞, - 3) U (7,∞)
