Answer:
16x
Step-by-step explanation:
80 divided by 5 is 16, so the student can read 16 words per minute. X is the number of minutes.
Nine I believe, because fifth teen divided by five equals three
three times three equals nine.
Divide 45 and 9 it was give you -5
Answer:
An equation for the inverse variation y = 2 when x = 5 is:
y=10/x
Step-by-step explanation:
Suppose that y varies inversely with x:
y=k/x
Write an equation for the inverse variation y = 2 when x = 5
Substituting y by 2 and x by 5 in the formula above:
2=k/5
Solving for k: Multiplying both sides of the equation by 5:
5(2)=5(k/5)
10=k
k=10
Then the equation is:
y=k/x
y=10/x
