Answer:
Step-by-step explanation:
The two sides add up to 12. If the third "side" of the triangle is 12, then 5 and 7 will lie horizontally on 12.
So the maximum value must be less than 12. What's the smallest x could be?
well 5 + something must be > than 7. If they are not larger than 7, then 5 and something will lie on 7 just as it did before. So how big is something?
5 + y > 7
5 - 5 + y > 7 - 5
y > 2
So the range is 2 < x < 12
How else could you write this?
2 < x
x < 12 is one way.
So, we have 4 cups of flour and 6 cups of sugar and we need to know how many cups of sugar per cup of flour does the recipe require. Because it is requested to know how many cups of sugar per cup of flour does the recipe require, we need to divide the amount of flour and sugar by the amount of flour, and we will know what we need to know.
4 cups of flour / 4 = 1 cup flour
6 cups of sugar / 4 = 6/4 = 3/2 = 1 1/2 cups of sugar per cup of flour is the solution
You don't need me to give you all six of them, because they're
all essentially the same problem. So I'll give you two, and lead
you close to the answer of another one, and by then, you should
be able to handle them on your own.
5). y/2 > 0 .
What can you do to the left side to get 'y' all alone ?
Multiply the left side by 2 .
But you always have to do the same thing to both sides.
Multiply each side by 2: y > 0 .

6). -4 < r/5
What can you do to the right side to get 'r' all alone ?
Multiply the right side by 5 .
But you always have to do the same thing to both sides.
Multiply each side by 5: -20 < r

7). 5c < 10
What can you do to the left side to get 'c' all alone ?
Divide the left side by 5 .
But you always have to do the same thing to both sides.
Divide each side by 5: c < ____
Over to you, champ !
