The first step for solving this problem is to multiply both sides of the bottom equation by -3.
Add the two equations together.
6x - 9y - 6x + 9y = 16 - 21
Eliminate the opposites.
-9y + 9y = 16 - 21
Remember that the sum of two opposites equals 0,, so the equation becomes the following:
0 = 16 - 21
Calculate the difference on the right side of the equation.
0 = -5
This means that the statement
is false for any value of x and y. That means that the answer to your question is (x,y) ∈ ∅,, or no solution.

Answer: The friend is taller...hope i helped.
Step-by-step explanation:
Convert so that they both are decimal then make a direct comparison.
5 feet
158 inches
→
5+112+(58×112)=5.1354...(me→5.1354..) is less than (friend →5)
Answer: the first one.
Step-by-step explanation:
because distance on a number line will always be positive. :D
Answer:
True, because they are under 180 degrees
"Supplementary angles are two angles with a sum of 18 0 ∘ 180 ^\circ 180∘ . A common case is when they lie on the same side of a straight line."
20% of 90 is 18
Explanation - 90 divided my 20 = 4.5 times 4 because 20 is 1/4 of 100
