<span>-2 (-7k + 4) + 9 = -13
Use distributive property
14k - 8 + 9 = -13
Add 8 to both sides
14k + 9= -5
Subtract 9 from both sides
14k= -14
Divide 14 on both sides
Final Answer: k= -1</span>

The answer is -1.


-2(-7k + 4) = -13 - 9

-2(-7k + 4) = -22

-7k + 4 = -22/2

-7k + 4 = 22/2

-7k + 4 = 11

-7k = 11 - 4

-7k = 7

k = -1.

Given that 35.8 x 4.23= 151.434<br>write down a division sum with an answer of 423.​
Nina [5.8K]

Answer:

  151434/358 = 423

Step-by-step explanation:

Every product with non-zero factors can be written as an equivalent division relation.

  a·b = c   ⇒   a = c/b

Here, we have 35.8 × 4.23 = 151.434. This can be written as the equivalent ...

  4.23 = 151.434/35.8

We can multiply this by 100 to get a division relation with a quotient of 423:

  423 = 15143.4/35.8

If we want, we can move the decimal points another place to the right to get ...

  151434/358 = 423
