Answer:
-2, 9
Step-by-step explanation:
Answer:
60 + x =100
Step-by-step explanation:
Since the angle with 100 degrees is opposite the angle combining 60 and x, they will have congruent measures.
Let
x------> parts produced by the first team <span>according to the plan
</span>y------> parts produced by the second team according to the plan
we know that
x+y=680--------> equation 1
0.20x+0.15y=118--------> equation 2
using a graph tool
see the attached figure
the solution is
x=320
y=360
the answer isparts produced by the first team according to the plan------> 320parts produced by the second team according to the plan----> 360

Answer: Yes that's correct
Work Shown:
(-1)^2-(-2-(9-1))
1-(-2-(8))
1-(-2-8)
1-(-10)
1 + 10
11
Note that (-1)^2 = (-1)*(-1) = 1, and subtracting a negative turns into a positive.
