1st the sum of y and 8 is
y+8
the quotient of 50 and (y+8) is simply dividing 50 by (y+8)
50 / (y+8)
Twice <span>the </span>quotient mean multiply <span>50 / (y+8) by 2, so t</span>he answer is:
2 * 50 / (y+8)

Answer:
300$
Step-by-step explanation:
divide 120 by 4 and then mutiply the answer on that by 10
Let f(x) represents the heart beat of the person.
Now, we have been given that person’s theoretical maximum heart rate is given by 220 - x.
Also, we have been given that person strive for a heart rate that is at least 50% of the maximum. At least means greater than equal to.
Thus, we have
Also, we have been given that person strive for a heart rate that is at most 75% of the maximum. At most means less than equal to.
Therefore, the system of inequality is given by
