4+ h ≤ 7 and h + 1 > 3

what is the value of the unknown number, h?

Step-by-step explanation:

4 + h ≤ 7        subtract 4 from both sides

4 - 4 + h ≤ 7 - 4

and

h + 1 > 3        subtract 1 from both sides

h + 1 - 1 > 3 - 1

h is greater then 2 and less or equal than 3

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
