Answer:

i think the answer is <u> 7 - x = 8</u>

Step-by-step explanation:

Let me explain why i think that is the answer. First off, i turned the problem around so it was easier for me to solve.

I think that it stays '7 - x' because they arent like terms so you cant combine them, so i think that stays the same. Because i cant change that, i added '2 + 9' and i got 11. I then took the 11 and subtracted it by itself and the 19. Because i subtracted it by itself, the 11 canceled out and i got 8 from the 19 - 11. Like i said, i couldnt do anything with the ' 7 - x' i ended up with 7 - x = 8.

Answer:

x = 12

Step-by-step explanation:

First you need to use the distributive property.

19 = 9 + 2x - 14

Then you should simplify (9-14)

19 = 2x - 5

+5         +5  (Then add 5 to both sides)

24 = 2x

/2     /2    (Divide by 2 to get x by itself)

12 = x

Hope this helps!!!

What is the greatest possible error if irina measured the length of her window as 3.35 feet? 0.5 0.05 0.005 0.0005
AlladinOne [14]

3.35 feet have a maximum inaccuracy of 0.005 feet.

The correct option is C.

<h3>What is error analysis?</h3>

When students consistently commit mistakes, an approach known as error analysis is frequently employed to determine the root of the problem. Reviewing student work is the first step in the process, after which misunderstood patterns are sought out. Mathematics mistakes can be conceptual, procedural, or factual, and they can happen for a variety of reasons.

<h3>Given:</h3>

The window is 3.35 feet long.

Find the biggest error you can

<h3>According to the given data:</h3>

Half of the measuring unit is considered to be the maximum amount of measurement error.

3.35 feet are calculated to the nearest centimeter, or 0.01 feet

Consequently, the largest conceivable error is equal to half of the measurement unit.

= .01/2

= .005

Therefore, the maximum inaccuracy for 3.35 feet is 0.005 feet.
