Answer:
There is approximately 5.475 liters of blood in the body.
Step-by-step explanation:
At a resting pulse rate of 75 beats per minute, the human heart typically pumps about 73 ml of blood per beat.
73 ml in liters = liters
Now, 75 beats/min x 0.073 liters/beat = 5.475 liters/min
And 5.475 liters/min x 1 min/body = 5.475 liters/body
Hence, there is approximately 5.475 liters of blood in the body.

Answer:
3h - 2
Step-by-step explanation:
An expression is a mathematical phrase using variables, such as 'h', and operations, such as addition, subtraction or multiplication. An expression does not include the equal sign (=).
The problem asks you to use the variable 'h' which we can substitute for 'a number' in the verbal description. Also, 'difference' is a word used for the operation of subtraction. 'Times' is a word that we use for the operation of multiplication. So, 'three times a number' = 3h. 'The difference of three times a number and two' = 3h - 2.
Answer:
a
Step-by-step explanation:
Given
y - 3 = (x + 6)
Multiply through by 2 to clear the fraction
2y - 6 = x + 6 ( subtract 2y from both sides )
- 6 = x - 2y + 6 ( subtract 6 from both sides )
- 12 = x - 2y, that is
x - 2y = - 12 → a
