200.
Twenty groups of ten = 20x10
20x10 = 200
Answer:
32 degrees
Step-by-step explanation:
The diagram of the problem is drawn and attached.
In Triangle WXZ
105+43+=180 (Sum of Angles in a Triangle)
148+=180
=180-148
=32 degrees
Since |XY|//|WZ| (parallel to)
= (Alternate Angles)
Therefore:
=32 degrees
Eight of the DVD with packing material is 0.19 lb.
1.10+8.5x=2.25+2.5x
Move variables to one side. The easier one would be to move 2.5x. So you subtract 2.5x to both sides.
1.10+6x=2.25
Do the same for the values without the x. The easier one would be to subtract 1.10 from both sides.
6x=1.15
Then divide by 6
1.15/6=0.19
