There is major 3 types of expression. Numerical expression, algebraic expression and fractional expression.
What is numerical expression?This expression contains only two or more numbers along with symbols or operator. There is no variable present.
such as 226÷113+2×22-11
or (44÷88) ×100%
the above sign is percentage sign we can determine a percent value
or∛ (64)
the above sign represents a cubic root
we get the value 4
What is fractional expression?The expression having two or more fractional terms along with symbols are called fractional expression. There are numerator and denominator from which we need to determine a common denominator to obtain a result.
such as, 4/5+3/4
we have 2 different denominators 5 and 4. we need to find a common denominator by multiplying both. 5x4
20
In the next, common denominator is divided by each denominator and the result is multiplied with each numerator.
(4×4+3×5)/20
hence, the result is 31/20
What is algebraic expression?
The expression contains both variables and numbers along with symbols are called algebraic expression. The algebraic expression having equal sign are termed as equation. Tha main purpose of using equation is to determine unknown value.
Algebraic expression are different types such as linear expression
2x+3-4y
2 and 4 are coefficient, 3 is constant
Polynomial expression as example 2x²-3y+4
Besides, we have other algebraic expression such as 3y+4 or x/4+y/3
and so on.

Which inequalities have 4 as a solution? 1. X-85.2 <_ 14.6 4. 8x <_ 128 2. X/6> -23 5. X+4.7>21.6 3. X-43<37 Put the numbers together to form the code.
Given:
The inequalities are:
1. [tex]x-85.2\leq 14.6[/tex]
2. [tex]\dfrac{x}{6}>-23[/tex]
3. [tex]x-43<37[/tex]
4. [tex]8x\leq 128[/tex]
5. [tex]x+4.7>21.6[/tex]
To find:
The inequalities that have 4 as a solution.
Solution:
We need to put [tex]x=4[/tex] in each inequality, to check whether it is a solution or not.
1. The inequality is
[tex]x-85.2\leq 14.6[/tex]
Putting [tex]x=4[/tex], we get
[tex]4-85.2\leq 14.6[/tex]
[tex]-81.2\leq 14.6[/tex]
This statement is true. So, the inequality [tex]x-85.2\leq 14.6[/tex] has 4 as a solution.
2. The inequality is
[tex]\dfrac{x}{6}>-23[/tex]
Putting [tex]x=4[/tex], we get
[tex]\dfrac{4}{6}>-23[/tex]
[tex]0.67\leq -23[/tex]
This statement is true. So, the inequality [tex]\dfrac{x}{6}>-23[/tex] has 4 as a solution.
3. The inequality is
[tex]x-43<37[/tex]
Putting [tex]x=4[/tex], we get
[tex]4-43<37[/tex]
[tex]-39<37[/tex]
This statement is true. So, the inequality [tex]x-43<37[/tex] has 4 as a solution.
4. The inequality is
[tex]8x\leq 128[/tex]
Putting [tex]x=4[/tex], we get
[tex]8(4)\leq 128[/tex]
[tex]32\leq 128[/tex]
This statement is true. So, the inequality [tex]8x\leq 128[/tex] has 4 as a solution.
5. The inequality is
[tex]x+4.7>21.6[/tex]
Putting [tex]x=4[/tex], we get
[tex]4+4.7>21.6[/tex]
[tex]8.7>21.6[/tex]
This statement is false. So,4 is not a solution of the inequality [tex]x+4.7>21.6[/tex].

Rhianna took a total of 10 pages of notes during 2 hours of class. In all, how many hours will Rhianna have to spend in class before she will have a total of 15 pages of notes in her notebook? Assume the relationship is directly proportional.
Answer:
Step-by-step explanation:
if 10 pgs = 120 mins
then 15 pgs = 15 × 120÷10
=1800÷10
= 180 mins
if 60 min = 1 hr
then 180 min = 180×1÷60
= 3 hrs
thus it will take her 3hours

2mm:6cm divided by 2 equals 1mm: 3cm
The required simplest form of 8mm; 24cm is 1mm; 3cm.
We have to determine, the simplest form of 8 mm: 24 cm.
To obtain the simplest form of the equation calculation must be done in a single unit following all the steps given below.
The ratio is just a way to compare two quantities while the proportion is an equation that shows that two ratios are equivalent.
Here, 8 mm: 24 cm.
Therefore,
[tex]8mm \ ; 24cm[/tex]
Divided by 8 both sides,
[tex]= \dfrac{8mm}{24cm}\\\\= \dfrac{1mm}{3cm}[/tex]
Hence, The required simplest form of 8mm; 24cm is 1mm; 3cm.

x + y = 8
2x2 – y = –5
Answer:
x=-2,y=10
Step-by-step explanation:
y=8-x.............equation 1
4-y=-5..........equation 2
Now,
putting the value of y in equation 2,
4-(8-x)=-5
4-8+x=-5
-3+x=-5
x=-5+3
x=-2
Then,
putting the value of x in equation 1
y=8+2
y=10
Line d has a slope of -8/3. Line e is perpendicular to d. What is the slope of line e?
Answer:
slope of line e=3/8
Step-by-step explanation:
we are given that line d's slope is -8/3, and we want to find the slope of line e, which is perpendicular to d
perpendicular lines have slopes that are negative and reciprocal; if you multiply the lines together, the result is -1
therefore, to find the slope of line e (m is the slope):
-8/3m=-1
multiply by -3/8
m=3/8
so that means the slope of line e is 3/8
Hope this helps!
Solve the equation 506x - 92y + 90 = 498 - 4x + 6y

Answer:
26.25 square feet
Step-by-step explanation:
Calculation to determine the area of the seat
Using this formula
Area=1/2*(b1+b2)*h
Where,
b1=8 feet
b2=7 feet
h=3.5 feet
Let plug in the formula
Area=1/2*(8+7)*3.5
Area=1/2*15*3.5
Area=26.25
Therefore the area of the seat is 26.25 square feet
