V +
= 8
First, simplify
to 3. / Your problem should look like: v + 3 = 8.
Second, subtract 3 from both sides. / Your problem should look like: v = 8 - 3.
Third, simplify 8 - 3 to 5. / Your problem should look like: v = 5, which is your answer.
Answer:
102 ≤ heart rate ≤ 183.6
Step-by-step explanation:
... lower limit ≤ heart rate ≤ upper limit
Put 16 where "a" is and do the arithmetic.
... lower limit = 0.5(220 -16) = 102
... upper limit = 0.9(220 -16) = 183.6
Then the inequality is ...
... 102 ≤ heart rate ≤ 183.6

<em>Comment on the problem</em>
There is nothing to "solve" here. One only needs to evaluate the limits.

Answer:constant of variation = 6/5
Step-by-step explanation:
t varies inversely as r
Let k be the constant of variation
t = k/r
t = 6 and r = 5
Substitute the value of t and r
6 = k/5
Make k the subject of the formula
k = 6/5
