Luis needs to run no less than 120 miles in order to go with the cross country team to a summer training camp. he has thirty days to pre-train for the camp. which inequality can be used to find how many miles luis must run each day to meet this goal?

30 days to run at least 120 miles

 120/30 = 4

let x = number of days

he needs to run at least 4 miles per day

 so x≥4  ( do any of your choices look like this?)

y = x + 95

y = 42 + 95

y=137 mm hg

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
