Is  = %

So 
 
88 = 110
 x      100

8800 = 110x
Divide both sides by 110

Answer:

Hamid's normal weight is 80 kg .

Step-by-step explanation:

Let us assume that the normal weight be x .

As given

Hamid has gained weight.

He now weighs 88kg, which is 10% higher than his normal weight.

10% is written in the decimal form

= \frac{10}{100}

= 0.10

10% increase in the weight = 0.10 × Normal weight.

                                             = 0.10 × x

                                             = 0.10x

Thus

Total weight of Hamid =  Normal weight + 10% increase in the weight

88 = x + 0.10x

88 = 1.10x

x = \frac{88}{1.10}

x = 80 kg

Therefore the Hamid's normal weight is 80 kg .

Make r the subject of t = 6r^2 + 6
SpyIntel [72]

First step, divide 6 from both sides.

t/6=r^2+1

second step, subtract 1 from both sides

t/6 -1=r^2

Now take the square root of each side.

\sqrt{\frac{t}{6}-1}=r

Done!
