X = 6 is a solution to the inequality x– 5 < 10

nikitadnepr [17]

Step-by-step explanation:

I am not sure what your problem is.

is this one line just a question to you ? is x=6 a solution ?

if that is the case then ... yes, x=6 is a solution to the inequality.

x - 5 < 10

x < 15

so, 6 < 15 is true, therefore, x=6 is a valid solution

The blood mass of a mammal is proportional to its body mass. A rhinoceros with body mass 3000 kilograms has blood mass of 150 ki

coldgirl [10]

Answer:

The equation which equates the two is M = $\frac{B}{20} = 0.05B$

A human with a body mass of 80 kilograms will have a blood mass of 4 kilograms.

Step-by-step explanation:

It is said that the blood mass is proportional to the body mass.

We can say that the blood mass of a mammal is M, and that the body mass of a mammal is B.

Since the two are proportional we can write

M ∝ B , or M = kB where k is the constant of proportionality.

Using the given values for a rhinoceros we can write

150 = k × 3000

Therefore k = $\frac{150}{3000} = \frac{1}{20} = 0.05$

Therefore the equation which equates the two is M = $\frac{B}{20} = 0.05B$

A human with a body mass of 80 kilograms will have a blood mass of

= $\frac{80}{20} = 4 kilograms$
