The value of the equation is A = 18
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = k + 12 be equation (1)
when k = 6
Substituting the value of k in the equation , we get
A = 6 + 12
A = 18
Therefore , the value of k is 18
Hence , the equation is A = 18

The total number of children in the club is given by the equation A = 160 students
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of students be represented as A
Now , the equation will be
The number of students who went to the matinee = 40 students
The percentage of students who went to the matinee = 25 %
So ,
percentage of students who went to the matinee x total number of students = number of students who went to the matinee
Substituting the values in the equation , we get
( 25 % ) x A = 40
On simplifying the equation , we get
( 25/100 ) x A = 40
A / 4 = 40
Multiply by 4 on both sides of the equation , we get
A = 160 students
Therefore , the value of A is 160 students
Hence , the equation is A = 160 students

Answer:
he needs to catch up by 5 pages
Step-by-step explanation:
Answer:
1. y = 35x
2. y = 30x + 1
3. y = 35x
y = 30 x + 1
4. Its more convenient to substitute y because It's easier.
35x = 30(x + 1)
5. 35x = 30x + 1
35x = 30x + 30
35x -30x = 30
5x = 30
x = 6 (30/5 = 6)
35 x 6 = 210 (y)
6. Both people have read 210 pages and it takes amir 6 days to catch up.

Answer:
x=7
Step-by-step explanation:
Add common variables.
(6x-4x)+7= 8+7x-26
2x+7= 8+7x-26
Subtract the least variable to both sides.
2x+7= 8+7x-26
-2x -2x
Now, simplify the equation.
7= (8-26)+5x
7= -18+5x
Add 18 to both sides.
7= -18+5x
+18 +18
Divide both sides by 5 to isolate the variable.
35= 5x
5 5
x=7
