Which of the following values are solutions to the inequality 1 + 5x < 4?
Romashka-Z-Leto [24]

Step-by-step explanation:

you cant add 1 to 5x, so subtract 1 on both sides leaving you with 1 + 5x < 4 that equals 5x < 3 -1 -1

then divide 5 from both sides 5x < 3 This leaves 5 5

you with x < 3/5

Gary ran 7 miles in 55 minutes what his rate of speed in miles per minutes
wel
I reccomend the search bar up at the top ("What is your question") before you ask questions, to make sure they're not already answered.

There is a formula d = rt, distance = rate*time. So
r = d/t.
r = 7mi/55min = 0.127mi/min


Or another way to see this:
\frac{7 miles}{55min} \frac{/55}{/55} = 0.127 mi/min
