Solving inequalities is almost the same as solving equalities for basic cases. Only thing you've to watch out for is signs.
For example, in 2x + 3 > 5,
We may subtract 3 from both sides,
2x > 2
Hence, by dividing both sides by 2, we get x>1.
The inequality sign changes on multiplying with (-)
For example, 2 < 6
But, -2 > -6
And when you interchange a fraction
E.g. 3/4 > 2/3
But, 4/3 < 3/2
You can now solve these of your own

Answer:
a) 7 tiles
b)4 1/3 tiles*
Step-by-step explanation:
*you would need 5 tiles if the answer isn't supposed to be a fraction. 4 1/3 is the exact amount but if they are asking for whole tiles you need to put 5. since they didn't actually specifiy that i don't think you have to worry about it. i would go with 4 1/3 tiles
Answer:
2472 students
Step-by-step explanation:
<u>What we know:</u>
- There are 6 schools
- Each school has 412 students
<u>What we're trying to solve:</u>
How many students are there altogether?
To find this, we multiply 412 by 6. Doing this is essentially the same as adding 412 to itself 6 times for each school there is in the district.
412 students × 6 schools
= 2472 students
Therefore, there are 2472 students in the district.
I hope this helps!
