<span>When converting a number with meters per second to a value with kilometers per second they best way to perform this operation is by using dimensional analysis or the factor label method. You would set up the equation starting with 5120 m/s times 1 km / 1000 m times 3600 s / 1 hr. It would look like this:
(5120 m/ 1 s) x (1 km / 1000 m) x (3600 s / 1 hr)
Your next step would be multiplying all the top numbers (numerators) together 5120 x 1 x 3600 = 18,432,000
Now multiple on the bottom numbers (denominators) together
1 x 1000 x 1 = 1000
Now you can divide the top product by the bottom product. 18,432,000 / 1000 = 18,432 km/hr is your final answer.</span>
Answer:
x ≤ 7/2
Step-by-step explanation:
Expand brackets: 3x - 15 ≤ x - 8
Subtract x from both sides: 2x - 15 ≤ -8
Add 15 to both sides: 2x ≤ 7
Divide both sides by 2: x ≤ 7/2
