Answer: 6+ 8 grams
Step by step:
1) subtract both numbers without grams
2) subtract both numbers with the grams
3) put together both sums subtracting each other
Answer: m= -2
7(m+5) = 21
7m + 35 = 21
-35. -35
7m = -14
————-
7. 7
m = -2
Well the link can be a video from yt. Like it can be related to your questions. Or it’s possible someone is trying to hack just be careful :)
In physics, work is equal to the product of force and distance, given that the direction of force is the same with the direction of the distance.
W = Fd
The total force is
F = 1,700 N + 500 N = 2,200 N
Now, if the question is the work needed to lift the barbell from the ground, the distance would be 2 m. Hence, the work would be
W = (2,220 N)(2 m) = 4,400 N·m or 4,400 J
Step-by-step explanation:
Given that,
The mass of a patient = 70 kg
A 70kg patient has approximately 8 pints of blood.
The patient donates 470mL of blood.
We know that,
1 pint = 568 mL
8 pints = 4544 mL
Required fraction,
So, the required fraction is approximately 
.
