Answer:
b = 30 / a
which agrees with the third expression in the list of possible options
Step-by-step explanation:
When we say that a and b vary inversely, that means that in mathematical form:
b = k / a where "k" is the so called "constant of proportionality". In order to write the function that models this inverse variation, we need to find the value of "k". We do such by using the information they provide (b = 5/2 when a = 12):
5/2 = k / 12
Then, solving for "k":
5 * 12 / 2 = k
60 / 2 = k
k = 30
Then we can now write the function that models this inverse variation:
b = k / a
b = 30 / a
14 meters = 140 decimeters and 15 meters=150 decimeters and so on
Answer:
3(x-10)=15
Step-by-step explanation:
assuming 152 is a typo
Answer:
=>1
=> 
=> Simplify:minus and minus simplify each other and so do 3 and 3
=> So were are left with 1
Thus,the answer is 1
