The difference between a hundred and a number is four times that number.

kotykmax [81]

Answer:

Step-by-step explanation:

Let the number be x

Four time that number = 4x

The difference between a hundred and a number = 100 -x

100- x = 4x

100 = x + 4x

100 = 5x

5x = 100

x = 100/5 = 20

8. 36.8 = [11.5 – (2.5 X 3)]2

Anestetic [448]

Answer:

$[11.5-(2.5*3)]^2=16$

Step-by-step explanation:

We want to evaluate $[11.5-(2.5*3)]^2$

Let us evaluate within the parenthesis first:

$[11.5-(2.5*3)]^2=[11.5-(7.5)]^2$

$\implies [11.5-(2.5*3)]^2=[11.5-7.5]^2$

We again subtract within the bracket to obtain:

$[11.5-(2.5*3)]^2=[4]^2$

This finally gives us:

$[11.5-(2.5*3)]^2=16$
