To estimate how many miles you are from a thunderstorm, count the seconds between when you see lightening and when you hear thunder. then divide by 5. write and solve an equation ti determine how many seconds you would count for a thunderstorm that is 2 miles away

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that

i could be wrong on this but im pretty sure that it is c

to solve for a variable means to isolate the variable on one side of the equation.

note: we can write (1/2)(bh) as one fraction like this (bh/2). they mean the same thing.

we now have this:

a = (bh/2)

we multiply both sides of the fractional equation by 2. this is done to remove the fraction.

doing this we now have a linear equation:

2a = bh

we now divide both sides of the equation by h to find the value of b.

final answer:

(2a/h) = b

the first answer is b

the second answer is b

the third answer is c

the fourth answer is b

the last answer is c

i hope i did this in time!
