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
60%
24/40 is 3/5
3 divide by 5 is 0.6
0.6 is 60%
you need to elaborate on this ?!?!?!
let me know when you do but DO NOT give me points cause i did not asnwer your question
