Step-by-step explanation:
Answer: 11/3 or 3.6 or 3 2/3
Step-by-step explanation:
All you have to do is simplify the expression
<em>Answer</em>
<em>To represent -5/3 on number line. Solution: </em>
<em>Take </em>a line X'X and a suitable point zero. On the right of 0 every 9t<em>h -s you indicate 1,2,3 etc. On the left of 0, every 9th -s you indicate -1 Or1', -2 or 2' , -3 or 3'.</em>
For the middle sections, you can use the area of a trapezoid: 1/2(h1+h2)b
1/2(1.25+2)1=1.625
The two triangles can form a square
1.25*1.75=2.1875
Add it all together
1.625+1.625+2.1875=5.4375
