It would take Phillip 7 monthes and 4 days to earn 60$$$
Answer:
1 
Step-by-step explanation:
Speed=distance/time
suppose the distance of the first day is d, and the time is t
distance of the second day: d+0.17d=1.17d
time of the second day: t+0.2t=1.2t
speed of the second day: 1.17d/1.2t=0.975(d/t)=(1-0.025)(d/t)
so the speed of the second day is 2.5% slower than the first day.
Answer:
property of equality that justifies the missing step is Division property of equality
Step-by-step explanation:
We need to Identify the property of equality that justifies the missing step

Now, we divide both sides by 4 using division property of equality as it states that 

So, The property of equality that justifies the missing step is Division property of equality
It would be: - 2 - (-10) = 5x - 12
= -2 + 10 = 5x - 12
= 8 + 12 = 5x
= x = 20 / 5
= x = 4
