Maria bought seven boxes. a week later half of all her boxes were destroyed in a fire. there are now only 22 boxes left. with how many do she start?

37 boxes

Step-by-step explanation:

If half were destroyed, that means that she had 44 total including the 7 she bought. This means, that to find the starting amount, you need to subtract 7 from 44:

44 - 7 = 37 boxes

I hope this helps!

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
