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
So the ratio is 100:60 and that simplified is 5:3. for every 5 blue there is 3 red
Answer:
x <-14.5
Step-by-step explanation:
2x + 2(x+5) <+4(8 – 20)
Distribute
2x+2x+10 < 4 (-12)
4x +10 < -48
Subtract 10 from each side
4x+10-10 <-48-10
4x< -58
Divide each side by 4
4x/4 < -58/4
x <-14.5
Answer:
50 degrees.
Step-by-step explanation:
The three angles make up a straight line angle which = 180 degrees, so:
C = 180 - 65 - 65
= 50 degrees.
