Answer:
The graph of linear inequalities include a dashed line if they are greater than or less than but not equal to. Linear equations, on the other hand, include a solid line in every situation. Moreover, linear inequalities include shaded regions whereas linear equations do not.
Step-by-step explanation:
Considering the definition of least common multiple, this means that smallest number of packages of each they can buy is 60.
<h3>Least common multiple</h3>
A number is a multiple of another when it contains it exactly n times. In other words, the multiples of a number are the ones you get when you multiply one number by another.
The least common multiple allows us to know what is the smallest number that is a multiple of a certain set of numbers.
One procedure for calculating the least common multiple is to break each number into prime factors. Then the common and uncommon factors are raised to the highest exponent, which must be multiplied.
<h3 /><h3>Smallest number of packages</h3>
To calculate the smallest number of packages of each they can buy, you calculate the least common multiple.
First, the decomposition of the numbers into prime factors is carried out:
15= 3×5
12= 2×2×3= 2²×3
Then, the least common multiple is calculated as 2²×3×5
Solving, the least common multiple between 12 and 15 is 60.
Finally, this means that smallest number of packages of each they can buy is 60.

In this case we know the three sides of the triangle, then this is a SSS triangle (Side Side Side). To solve this case, first we must use the Law of Cosines, applied to the opposite side to the angle we want to find.
We want to find angle W, and its opposite side is XV, then we apply the Law of Cosines to the side XV:
XV^2=XW^2+WV^2-2(XW)(WV)cos W
Replacing the known values:
116^2=96^2+89^2-2(96)(89)cos W
Solving for W
13,456=9,216+7,921-17,088 cos W
13,456=17,137-17,088 cos W
13,456-17,137=17,137-17,088 cos W-17,137
-3,681=-17,088 cos W
(-3,681)/(-17,088)=(-17,088 cos W)/(-17,088)
0.215414326=cos W
cos W = 0.215414326
Solving for W:
W= cos^(-1) 0.215414326
Using the calculator:
W=77.56016397°
Rounded to one decimal place:
W=77.6°
