(9m - 6)7
Distribute 7 to both sides
63m - 42
Add 42 to get 63m by itself
63m = 42
Divide both sides by 63
m = 42/63 or simplified, 2/3
Answer:
and 
Step-by-step explanation:
We know,
'Direct Variation function' is the function where two quantities vary directly i.e. variables x and y are said to be directly varying if 'y=kx' where k is the constant of variation.
Thus, from the options, we see that the function,
is varying directly with the constant of variation i.e. k = 1.
is also varying directly with constant 
Answer: There are 12 pairs of tennis shoes.
Step-by-step explanation:
Since we have given that
For each pair of tennis shoes , she owns 4 pairs of flip flops,
so their ratio will be 1:4
Let the number of tennis shoes be x
Let the number of flip flops be 4x
According to question,
4x-x=9
3x=9
x=\frac{9}{3}
x=3
So, the number of pairs of tennis shoes is given by

Hence, there are 12 pairs of tennis shoes.
The lightest it will weigh will be 4.3 Pounds
