Let the constant of variation be c.
We are given that y varies inversely with 2.5x, this means that:
y = (c) / (2.5x)
This can be written as:
2.5xy = c
Now, we a re given that y = 5.6 at x = 30.
Substitute with these values in the equation to get the value of c as follows:
2.5xy = c
2.5(30)(5.6) = c
c = 420
Therefore, the equation that describes the relation is:
2.5xy = 420
Answer:
A rhombus and a square since a square is also a rhombus.
She can mostly add 35 and 9 and it will give you 44
<span>9 + (-4) - 6
<em>[open the bracket, +(-) = - ]</em>
</span>= 9 - 4 - 6
<em>[Both operations required are -, work from left to right]</em>
= 5 - 6
= - 1
