EleoNora [17]2 years ago
8 0

Answer:

Step-by-step explanation:

-7k = 0

Divide both sides by (-7)

k = 0

17) c - 4 = -23

Add 4 to both sides

c - 4 + 4 = -23 + 4

           c = - 19

18) \dfrac{r}{-2}=-16\\\\\\Multiply \ both \ sides \ by \ (-2)\\\\\dfrac{r}{-2}*(-2) = (-16)*(-2)\\\\\\r = 32

What is the rational number equivalent to 3.24​
aev [14]

Answer:

The rational number equivalent to 3.24 repeating is 321/99

Step-by-step explanation:

To convert the decimal number to a rational number we can state this number and its multiples of 10, trying to find two number with identical decimal parts:

n=3.24242424...

10n=32.4242424....

100n=324.2424242...

Now, 100n and n have the same decimal part, then by subtracting these numbers we obtain:

100n-n=324.24242424...-3.24242424... = 321

99n  = 321

n = 321/99

Two integers have a sum of -44 and a difference of 22. The greater of the two integers is
Leni [432]

Answer:

  -11

Step-by-step explanation:

The generic solution to ...

  • a + b = sum
  • a - b = difference

Can be found by adding the two equations:

  (a+b) + (a-b) = (sum) + (difference)

  2a = (sum + difference)

  a = (sum + difference)/2

___

Our particular solution is ...

  a = (-44 +22)/2 = -11

The greater of the two numbers is -11.

___

The other number is -33.

What are the rules for adding and subtracting negative numbers?
Alexeev081 [22]
A negative sign and a negative sign next to each other is a positive sign ex..

-14 - -3
= -14 + 3
= -11

a negative sign and a positive sign next to each other is a positive sign ex..

-14 + -3
= -14 - 3
= -17

the bigger a negative number the smaller it is
the bigger a positive number the larger it is
which supports the rule if you are subtracting the
number will become smaller and if you are adding
the number will become larger
