(-5)(8) = -40
you multiply -5 by how many wrong answers u got
Answer:
6x<100-15
6x<85
x<85/6
x<14.17
Step-by-step explanation:
<em>Greetings from Brasil...</em>
Just 2 equal angles are enough for the triangles to be similar .... The second triangle has the same angles as the first.
We know that the sum of the internal angles of a triangle is 180, so for the second triangle:
84,6 + 65 + X = 180
X = 180 - 84,6 - 65
X = 30,4 → same angle as the largest triangle
So we have AA~ similarity
The total cost would be $191.49
Not rounded up so round it up to .50 if you have to :)

making x the subject

substitute into second equation

by solving, y=5
substitute into first equation

by solving, x=-3
Therefore the ordered pair is (-3,5)
