Answer:
#5 x=8, #6 x=5
Step-by-step explanation:
Theyre vertical so for number 5 you would have the equation
5x+15=55
-15 -15 from both sides
5x=40
divide by 5 from both sides and you get
x=8
Same thing vertical so you would have
16x+7=87
-7 -7 from both sides
16x=80
divide by 16 from both sides
x=5
Answer:
Step-by-step explanation:
given are two vectors
a) A+B = sum of twovectors = simply adding corrsponding compnents
=
Magnitude of the above vector =
Direction is making an angle of arc tan (-3) with x axis
b) A-B = Difference
=
Magnitude of difference vector =
Direction is making an angle of arctan (1/2) with positive x axis.
(angle = arctan (jcomponent/icomponent)

Answer:
3.875 lb
Step-by-step explanation:
Weight of table = 19lb 4 oz = 19-4/16 lb = 19.25 lb
Weight of each chair = 11 lb 9 oz = 11-9/16 lb = 11.5625 lb
Weight of 2 chairs = 2 x 11.5625 = 23.125 lb
Difference in weight between 2 chairs and one table
= 23.125 - 19.25
= 3.875 lb
