Answer:
1st part: 12mph
2nd part: 60 more miles
Step-by-step explanation:
So first, you need to find the mph (miles per hour) each person is traveling at before doing anything else. And to find this, jus divide the number of miles traveled by the hours it took:
Greg: 240 miles / 5 hours = 48 mph
Max: 180 miles / 3 hours = 60 mph
Therefore, you answer to the first one is just 60mph - 48mph which is 12mph faster
The second part, since you know the mph, you can just plug the numbers in:
Greg has travelled 240 miles after 5 hours and if Max goes for 2 more, it’s 2 hours (Max’s mph) -> 2(60) -> 120 miles (this is the amount of miles that Max covers in only 2 hours). We have to add 120 to the 180 miles that Max already has travelled, which gives us the sum of 300 miles in total. Now, we can just subtract: 300 miles - 240 -> 60 more miles (the answer for the second one)

Answer:
-4
Step-by-step explanation:
Solve this like a normal equation. Pretend the ≤ is an equal sign. Then isolate the variable. Subtract 7 from both sides, and that will give you -4
Step-by-step explanation:
x=1
=2^3×1-1
=8×1-1
=8-1
=7
