Fofino [41]

Answer:

87 + 8r

Step-by-step explanation:

We have a variable that we cannot simplify further:

8r

But we have two numbers that we can simplify:

94 - 7 = 87

Then we add those together:

8r+87

PLEASE HELP ASAP Hi! Please help me guys!!! This is difficult for me.. :c ~Why might a solution to an inequality not be reasonab
abruzzese [7]

Answer:

When the solution is negative

Step-by-step explanation:

One example, let's say you are buying pens and each pen cost 3 dollars and you cannot spend more than 15 dollars, how many pens can you buy?

The inequality would be 3x < 15, so any negative solution is not reasonable because you cannot buy negative pens. The same goes for most real-world problems dealing with time, money, or distance.
