Answer:
<u>a = 13</u>
Step-by-step explanation:
We should know that: The sum of the interior angles of the triangle = 180°
Given the measure of the angles: (6a - 2) , (5a - 13) and (5a - 13)
So,
(6a - 2) + (5a - 13) + (5a - 13) = 180°
16 a - 28= 180 ⇒ Add 28 to both sides
16 a = 180 + 28 = 208 ⇒ Divide both sides by 16
a = 208/16 = 13
For this case we have the following system of equations:

When solving the problem graphically we must take into account the following:
1) The solution of the system of equations is given by the intersection of both functions.
2) The solution is an ordered pair of the form (x, y)
For this case we observe that the solution is given by:

Note: see attached image.
Answer:
The approximate solution to the system is (1.23, 4.39)
The solution to a system of linear equations is (0, 4). One of the linear equations in the system is y = 8.1 +4.the answer is 12.1
Answer:
it would be 10 soccer balls
Step-by-step explanation:
10 every week if it was constant (because they could've sold more one week then less the next) but the genuine answer is 10 soccer balls :)
