Arrange the tiles on both boards to model the equation.
Use the algebra tiles to model the equation
2x + 4 = 3x + (-1). Then complete the sentences.
To model 2x + 4, you need:
positive x-tiles to represent 2x.
pl sitive
positive unit tiles to represent 4.
3
To model 3x + (-1) you'll need:
x-tiles to represent 3.x.
unit tile to represent-1.
Board sum: 0

to complete this square you have to rotate about the origin 270 degrees clockwise.

step-by-step explanation:

a fish tank full of water and then fish, regardless of the shape of it, has a certain volume.   volume is how much of something fills up the inside of a shape.   if the shape of the tank is a sphere, thr volume formula for a sphere is

we are given that the diameter of the sphere is 14, so that means that the radius is half of that at 7.   filling in to find the volume of the sphere:

do the math on that and you find that the volume of the tank is 1436.755

if there is to be 1 fish for every 693 cubic inches, we must divide the total volume of the tank by 693 to get the number of fish that will fit comfortably.

1436.755/693 = 2.07

since you can't have .07 of a fish, we round down to the nearest whole number to get that 2 fish will be able to swim comfortably in the tank.
