Answer:
It's just a simultaneous equation
Step-by-step explanation:
Let a big bag of sugar = x
Let a small bag of flour = y
x+x+y = 12kg
2x+y = 12kg ... 1
x-y = 2kg ... 2
Add 1 and 2
2x+y = 12
+
<u> </u><u> </u><u>x</u><u> </u><u>-</u><u>y</u><u> </u><u>=</u><u> </u><u> </u><u>2</u>
3x = 14
x = 14/3 = <u>4.66</u>
Substitute value of x into 1
2(4.66)+y = 12
9.333 + y = 12
12 - 9.333= 12
y = <u>2</u><u>.</u><u>6</u><u>6</u>

Answer:
1,260 sq ft
Step-by-step explanation:
FORMULA TO FIND AREA OF A RECTANGLE: L*W, l=length, w=width
we can divide the figure into three other rectangles
rectangle one) length=20 width=10
so 20*10=200
rectangle 2) length=45, width=20
so 45*20=900
rectangle 3) length=20 width=8
so 20*8=160
now we add up the areas of the 3 rectangles to find the area of our figure
200+900+160=1,260 sq ft
hope this helps!
It is -7w.
