180-50=130
x-y=130
x+y=50
2x=180
x=90
90+y=50
y=50-90
y=-40
It’s just y= 17x. There’s nothing added or subtracted, or else it wouldn’t be (0,0).
This not might be correct (Cause in a middle schooler) but I think is....
440 divides by 24 = 18.3333333
We round it to the neared whole number which is 18.
18 x 2.80 = 50.4
So it is 50.4 altogether...
9x+5-4x-3=5x+2. You combine like terms after multiplying by negative sign.
You first find the area of one piece. The small squares are 4 and there are two so you have 8 so far. The length of the rectangles are 4 and using the width of the square (2) and you multiply, then you get 8 per rectangle, there are 4 rectangles so the total area of the rectangles are 32 adding the 8 from the squares, you get 40 square feet. (2*2*2)+(4*2*4)=40 square feet. Hope this helped!
