Answer:
The equation is b = -a
Step-by-step explanation:
Given,
The number b varies directly with the number a,
That is, we can write,
b ∝ a
⇒ b = ka
Where k is the constant of proportionality,
Given, if b = 2 then a = -2,
By substituting the value,
2 = k(-2)
⇒ k = -1
Hence, the equation that represents the direct variation between a and b is,
b = -a
it is a function

51 ÷ 7.2 is about 7.08 continued but you can't make .08 of a braclet so it's just 7
I think the answer is 381.7
