Answer:
Step-by-step explanation:
To calculate how much more blood flows per minute to the skeletal muscles during intense exercise than during rest, we need to use the following formula:
exercising - resting = increased blood flow
Substituting the given values, we get:
exercising - resting = increased blood flow
exercising - 1,200 cm³/minute = 4.CC
To solve for exercising, we need to isolate the variable on one side of the equation. Adding 1,200 cm³/minute to both sides, we get:
exercising - 1,200 cm³/minute + 1,200 cm³/minute = 4.CC + 1,200 cm³/minute
exercising = 4.CC + 1,200 cm³/minute
Therefore, the equation to calculate how much more blood flows per minute to the skeletal muscles during intense exercise than during rest is:
exercising = 4.CC + 1,200 cm³/minute
