If a man 73kg man weighs himself at the North
Pole and at the Equator, the difference in weight in Newtons is 719.37. I
am hoping that this answer has satisfied your query about this specific
question, thank you and have a nice day.
Slimination
multiply first equaiton by 2
2x+6y=10
add to second equiaotn
2x-2x+6y-6y=10-10
0=0
this is true so therfor they are the same equaiton
so solve
x+3y=5
3y=-x+5
y=-1/3x+5/3
subsituter values for x and get valuse for y
if x=2 then y=1
a)
F =
(K - 273.15) + 32
<u>- 32</u> <u> - 32</u>
F - 32 =
(K - 273.15)
(F - 32) =
[
(K - 273.15)]
(F - 32) = K - 273.15
-
= K - 273.15
- 57.6 = K - 273.15
<u> + 273.15</u> <u> + 273.15 </u>
- 215.55 = K
b)
- 215.55 = K
324 - 215.55 = K
108.45 = K
X = 180 - 42 - 73 = 65 degrres
y = 180 - 131 = 49 degrees
< z = 65 + 49 = 114 degrees (answer).
Answer:
3.5(11) means 3.5 times 11? in that case
Step-by-step explanation:
first one roughly = 35+19+16....then you can see 77 is the closest, even without calcatulor
second one precisely==20+33+5+38.....then you can see that 90 is roughly the closest one, again even without to add those 4 togetherly precisely
