someone please help

Answer 4

If 3 times the rainfall is increased by 2, the rainfall is still less than 26 inches.
2.5 plus twice the rainfall is greater than 11 inches.
let rainfall be x

3(x+2) < 26 inches
2.5 +2x >11 inches

Answer 5

ok so 3(x+2) < 26 inches
2.5 +2x >11 inches is part A ?

Answer 6

yes but i made a mistake first one should be 3+2 <26

Answer 7

ok

Answer 8

3x+2<26 *

Answer 9

alright

Answer 10

ok u have these inequality , could u solve them ?
3x+2<26
2.5 +2x >11

Answer 11

umm i dont know how to

Answer 12

for first one
3x+2<26
3x<24
x<24/3
x<8 , thus set of solution :-

for
2.5 +2x >11
2x>8.5
x>4.25



so range of solution would be :-
4.25<x<8

Answer 13

Ok but how do you put that into a answer for part b
