Answer:
it is many triangles
Step-by-step explanation:
<u>Given</u>:
The system of linear equations are
and 
We need to determine the solution to the system of equations using substitution method.
<u>Solution</u>:
The solution can be determined using the substitution method.
Let us substitute
in the equation 
Thus, we have;




Thus, the value of y is -17.
Substituting
in the equation
, we get;


Thus, the value of x is -13.
Hence, the solution to the system of equations is (-13,-17)
The area in which the right angle was at before. the angle nor the triangle changes
If there are 5 people, they get 3 cans.
We want to give the same amount of soup to everyone, so if there are twice as many people, we're going to need twice as much soup.
(10 people, 6 cans)
Now say we had 20 people. (4 times as many)
We'd use 4 times as many cans soup, which would be 3×4 = 12 cans.
So it seems tht both B and D are correct.
