Mathematics
1 answer:
mrs_skeptik [129]4 years ago
3 0

Answer:

x = -7

Step-by-step explanation:

8x - 9 = 12 + 11x

Subtract 11x to both sides of the equation. Then, it will look like this:

-3x - 9 = 12

Add 9 to both sides of the equation. After that, it will look like this:

-3x = 21

Divide both sides of the eqution by -3. Your answer is:

x = -7

Question about decimals
meriva

Answer:

  • Both are terminating decimals

Step-by-step explanation:

<u>Answer to your questions:</u>

  • First of all, both A and B are correct and both quotients are terminating decimals.
  • To find out if the decimal is terminating or not, multiply the quotient by divisor. If you get exactly the same number as dividend, then it is terminating otherwise it is non-terminating.
  • The fraction may have greater numerator than denominator, in this case the quotient will be greater than one.
  • Now regarding simplification. You would be asked to give an answer rounded to some extend.  One decimal place, two decimal places, 3 significant numbers etc. For the first operation you would get 34.8 (rounded to nearest tenth).
  • Or you may be asked to have a best estimated result. In this case you would round the initial numbers and find results. 205/714 ≈ 0.29
