Answer:
-5 cannot be a possible solution
Step-by-step explanation:
given:
4h > -12 (divide both sides by 4)
h > (-12) / 4
h > -3
Hence all possible solutions of h must have a value greater than -3.
Since -5 is less than -3, hence -5 cannot be a possible solution
Answer:
8.652
Step-by-step explanation:
Ignore the points and multiply, then you see that 4.12 has two decimal places and that 2.1 has one decimal place, when you add them there is three decimal places.
412 x 21 = 8652
4.12 x 2.1 = 8.652

Answer:
1244/999
Step-by-step explanation:
So we have 1.245245245245.... which we call x.
If we times this by 1000 (because 3 digits repeat) we get
1000x = 1245.245245245....
Subtract x from both sides:
999x = 1245.245245245... - 1.245245... = 1244
This means that x = 1244/999
This fraction cannot be simplified so this is the answer.
If you want to include the 1 in the repeating (1.2451245...) do the same but the sequence is 4 digits so times by 10000 instead.
