Man i've missed 3 weeks of math : ((
1. -11 < b + 9
2. -26 > -14 + m
3. -3 < m - 7

1. b>-20

2. m<-12

3. m>4

Step-by-step explanation:

1. -11<b+9

-20<b

2. -26>-14+m

-12>m

3. -3<m-7

4<m

Just solve these easy inequalities like any other equation. Ask you teacher about the ones with negative coefficients on the variable. For example, -2m<10.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
