A number is :

_________________________________
Three quarters of it means :

_________________________________
Decrease by 20 means :

_________________________________
Equals to 82 means :

_________________________________
What is that number ?
x asked so we must solve the above equation for x.
Let's do it....

Plus sides 20


Multiply sides by 4

Divided sides by 3


Simplify


So that number is 136 .

Evaluation of the expression using order of operation gives 26/11.
How to evaluate the expression
Given 13 ÷(2.5-1-3).33 = 13 ÷ 33( 2 x 5 - 1 - 3)
To evaluate this expression we need to apply the order of operation rule, BODMAS or PEMDAS.
13 ÷(2.5-1-3).33 = 13 ÷ 33( 2 x 5 - 1 - 3) Evaluate multiplication
= 13 ÷ 33(10 - 1 - 3) Evaluate what is in the bracket
= 13 ÷ 33(6) Evaluate division
= 13/33 x 6
= 78/ 33 = 26/11
Therefore, evaluating the expression gives 26/11.

Answer: -3.
Step-by-step explanation:
We are given that :
(1)
It means that f(x) and g(x) are proportional.
[Equation of direct variation: y=kx , where k= proportionality constant.]
From the given graph ,
At x= -3 , f(x)=1 and g(x) =-3
Put value of x=-3 in (1) , we get
[∵ f(x)=1 and g(x) =-3]
i.e. The value of k = -3
Hence, the correct answer is -3.
