A young sumo wrestler goes on a special diet to gain weight.
Ilia_Sergeevich [38]

Answer:

10.8 kg

Step-by-step explanation:

w = 80 + 5.4t

At time 0, when he starts the diet, his initial weight is

w = 80 + 5.4(0)

w = 80

80 kg.

After 2 months, t = 2. His weight is

w = 80 + 5.4t

w = 80 + 5.4(2)

w = 80 + 10.8

w = 90.8

90.8 kg.

His gain in 2 months was 90.8 kg - 80 kg = 10.8 kg

Answer: 10.8 kg

If c+1/d=5 , what is the value of 30d/2c+2
klemol [59]

Answer:

3

d\in R,\hspace{5}d\neq 0

Step-by-step explanation:

You can solve for any variable. From the first equation, let's solve for c :

\frac{c+1}{d} =5\\\\c+1=5d\\\\c=5d-1

Now, replace the value of c into the other equation:

\frac{30d}{2c+2} \\\\\frac{30d}{2(5d-1)+2} \\

Using distributive property

\frac{30d}{10d-2+2} =\frac{30d}{10d} =3

However, keep in mind that this is true for:

d\in R,\hspace{5}d\neq 0
