Given that,
To determine the number whose 62.5% is 2.25.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Given that,
Let the number be x,
According to the condition,
62.5% of x = 2.25
0.625x = 2.25
x = 2.25/0.625
x = 3.6


Thus, the required number whose 62.5% is 2.25 is given as 3.6.

What is an expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, Maya is 14 years old. Her brother Jorge is 3 years more than half her age.

We need to determine an expression for Jorge's age,

So, If you divide her age by two and add 3 then you will get Jorge age and that is what the question is asking,

i.e. (14 ÷ 2) + 3

Hence, the correct expression for Jorge's age is (14 ÷ 2) + 3

Answers

Answer:

(0,20)

Step-by-step explanation:

1) we can represent the situation as coordinates

lets have # of texts be "x" variable

lets have bill be "y" as the y variable is always the dependant variable and the cost of the phone bill is dependant upon the number of texts so

y=mx+b-slope-intercept form

coordinates: (50,25) and (100,30)

slope: (30-25)/(100-50)

5/50=1/10

hence slope=1/10

y=1/10x+b

substitute in a coordinate pair into this equation

25=50*1/10+b

25=5+b

b=20

hence y intercept is (0,20)
