Aschool needs 25 butterfly breeding kits, and places an order with an educational company. they already have 7 kits, and they receive a box with x kits, but still need 3 more kits. write the equation that you can use to find out how many kits are in the box.

You can write an equation like this:

7 + x = 25 - 3

The amount they have (7) plus the amount they received (x) is 3 less than the amount they need (25). It simplifies to:

7 + x = 22

To solve, isolate the variable by subtracting 7 from each side:

x = 15

The box contained 15 kits.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
