Answer: 12 packages with 5 notebooks and 6 pencils in each package.
Step-by-step explanation:
The greatest common factor of 60 and 72 is 12. Thus divide both numbers(60 and 72) by 12 to get 5 and 6. Thus, Miss Smith made 12 packages with 5 notebooks and 6 pencils in each package.
6 is the greatest common factor of 12 and 30
So this is easy counting
so 5x^2-3x-9
we have 5 x^2's
-3 x's
-9
wat do we add to that to get
1 x^2's
-5 x's
+6
so we do each
5x^2+what=1x^2
subtract 5x^2
from both sides
what=-4x^2
first is -4x^2
then we have -3x to -5x
-3x+what=-5x
add 3x to both sides
what=-2x
second is -2x
-9 to 6
-9+ what=6
ad d9
what=15
last is 15
thereffor add -4x^2-2x+15
Answer:
<em>17 miles</em>
Step-by-step explanation:
If Heidi starts out by traveling 15 miles south, then y = -15 miles
If she then turns and rides 8 miles east, then x = +8miles
The distance from her starting position to her tent is gotten using the pythagoras theorem as shown;
d = √(-15)²+8²
d = √225+64
d = √289
d = 17miles
<em>Hence her distance from her starting position to her tent is 17 miles</em>
