Question

5. Draw the number line graph of -3.

6. What does |-9| equal?





7. Solve the equation y – 11 = -4.





8. Evaluate the expression a + b when a = 2.5 and b = -10.8.






9. Draw the number line graph of 0.4.





10. Insert < or > to make this statement true: -1.8 -2.5

Answer 1

9, 7,-8.3,>

Explanation:

5)-3 is marked exactly 3 units to the left of origin 0.

(since negative sign we mark on left of 0)

6) |-9| = absolute value of 9 = 9

7) y-11=-4

Add 11 to both the sides

WE get y =7 is the solution

8) a + b when a = 2.5 and b = -10.8.

= 2.5+(-10.8) = -(10.8-2.5) = -8.3

9) 0.4 is positive hence lies to the right of origin.

Partition the space between 0 and 1 into 10 equal subparts and mark 4th subdivision to get 0.4

10) -1.8>-2.5
