Answer:
3(2x+5)=3 6x+15 = 3 6x = -12 x =-2
9+9x=2x+2 9x-2x= 2-9 7x= -7 x=-1
Step-by-step explanation:
Answer:
-3/9x
Step-by-step explanation:
You rearrange for 'y' so divide both sides by it's coefficient which is 9.
Answer:
B. 550
Step-by-step explanation:
550 is the smallest number that becomes 600 when rounded to the nearest hundred
The possible values for the third side's measurement are3 < x < 17. Any two sides of a triangle's lengths added together must be longer than the third side.
<h3>How do you determine a triangle's perimeter?</h3>
- The third side of a triangle must always have a length that is between (but not exactly) the sum and the difference of the other two sides.
- Any two sides of a triangle's lengths added together must be longer than the third side.
- Each side of a triangle with sides a, b, and c must fall within the difference and total of the other two.
- For instance, side a must be between b-c and b+c or b-cab+c.
- The third side must fall between 10 -7 = 3 and 10 + 7 = 17.

The answer is B-about 18km
This is because you round 18.23 to 18km
then you round 13.94 to 14km
you add these rounded numbers together
you take it away from 50km
the answer would then me 18km
but it be ABOUT because that was only a rough estimate because it was rounded
