Papessa [141]

Answer:

1. -4(6)= -24

2.-21-8= -29

3. 121-4 =117

4. -6(5) =-30

5. -10(-9)= 90

6. (-5)7= -35

7. (-5)8= -40

8. -30(5)= -150

9. 20(-6)= -120

10. -14(6)= -84

11. (-13)2 = -26

12. –7(15) = -105

13. -3(4) = -12

14. 7(-3) = -21

15. 3(-3) = -9

16. -2(-10) = 20

17. (-5)(-3)(4) = 60

18. -3(-3)(4)= 36

19. -3(-5) = 15

20. 5(-3) = -15

21. 7(-5)(4) = -140

22. -2(-5)(-3)= -30

23. – 10(-3)=30

24. -21-3= -24

Explanation:

We have followed the rules in adding and subtracting negative as well as positive values on the number line.

When adding two negative values, the result is a negative value.

When adding a negative and positive value, the result is either a positive or negative value depending on if the negative value is bigger or smaller than the positive value

When multiplying two negative values, the result is a positive value

When multiplying one negative and one positive value, the result is a negative value

To make you understand addition and subtraction of negative and positive numbers better, let us use a simple analogy. Assuming you are owing five oranges(-5) and you are only able to give two oranges(+2), you will still be owing 3 oranges(-3). Assuming also that you are owing 6 oranges(-6) and you are able to give 8 oranges(+8), you would have given excess oranges and would be owed two oranges(+2). Hence the results above.

ANEK [815]

Answer:

<h3>Negative StartFraction 7 over 10 EndFraction </h3>

Step-by-step explanation:

Given the expression \frac{1}{2} - 1\frac{1}{5}, we are to find the difference

First convert the mixed fraction 1\frac{1}{5} to improper fraction

1\frac{1}{5} = \frac{6}{5}

The expression becomes;

\frac{1}{2} - \frac{6}{5}

Find LCM

\frac{5-6}{10}

Evaluate the resulting expression

\frac{5-12}{10}\\\\\frac{-7}{10}

Hence the correct option is C i.e Negative StartFraction 7 over 10 EndFraction

BabaBlast [244]

Answer:

Step-by-step explanation:

percent increase = ((new number - original number) / (original  number))  * 100

                             = ((910 - 650) / 650)  * 100

                             = (260 / 650) * 100

                             = 0.4 * 100

                             = 40% <===== Maki's  increase
