What is equation modelling? What is a mathematical equation and expression?
- Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
- A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
- A mathematical equation is used to equate two expressions.
Given is that on Sunday, a local hamburger shop sold a combined total of 428 hamburgers and cheeseburgers. The number of cheese burgers sold was three times the number of hamburgers sold.
Assume that the number of hamburgers sold are [x]. Then, the number of cheese burgers sold will be [3x]. Then, we can write -
x + 3x = 428
4x = 428
x = 17
Therefore, the total number of hamburgerssold were 17.

you solve for x and get 4x= 428 and x=107
so 321 hamburgers were sold that day.

6y-8=10
then add 8 to both sides
6y=18
then divide by 6 on both sides
y=3
and if you plug it back in it should equal 10
2((3)(3)-4)=10
10=10

A function means that each x can only have one y-value
B, C, and D are NOT functions because they have x-values that have multiple y-values.
For example
B. has two values for -4:
(-4, 8) and (-4, -8)
C. has two values for 9:
(9, -1) and (9, 2)
D. has two values for 5:
(5, -7) and (5, 9)
This makes A. the only function

The improperfraction of 1(1/3) is 4/3.
What is a fraction?
A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
We have two types of fractions.
Proper fraction and improper fraction.
A proper fraction is a fraction whose numerator is less than the denominator.
An improper fraction is a fraction where the numerator is greater than the denominator.
Example:
1/2, 1/3 is a fraction.
3/6, 99/999 is a fraction.
1/4 is a fraction.
We have,
1 and 1/3
An improperfraction means the numerator is greater than the denominator.
So,
1 and 1/3
= 1(1/3)
= (3 x 1 + 1) / 3
= 4/3
4 > 3 so it is an improperfraction.
Thus,
The improperfraction of 1(1/3) is 4/3.

Answer:
4/3
Step-by-step explanation:
to change a mixed number to an improper fraction, you have to multiply the denominator by the whole number and add the numerator to the product. This is your numerator. The denominator stays the same.
Thus,
Numerator = 3 x 1 +1 = 4
Denominator = 3
Fraction = 4/3
