The <em>correct answers</em> are:
Top circle: 34
Bottom left: 9
Bottom right: 21
Explanation:
Let the top circle be x, let the bottom left circle be y, and the bottom right circle be z.
Following the diagram, we have the following equaitons:
x+y = 43
y+z = 30
x+z = 55
Taking the first two equations as a system, we will eliminate y:
We will subtract the bottom equation from the top:
We will now take this and the last equation as a system; this time, we will eliminate z by adding the two equations:
Divide each side by 2:
2x/2 = 68/2
x = 34
Substitute this into the first equation:
x+y = 43
34+y = 43
Subtract 34 from each side:
34+y-34 = 43-34
y = 9
Substitute this into the second equation:
y+z = 30
9+z = 30
Subtract 9 from each side:
9+z-9 = 30-9
z = 21
3.4:
the word form would be three and four tenths
the expanded form would be :
3.0 = 3
0.4 = .4
2.51:
the word form would be two and fifty one hundredths
the expanded form would be 2.00 + 0.50 + 0.01
