to first solve this we need to write an equation by find time
T+50+95
-50 - 50
t= 45
then we have to find hour
h=45+50+95
45
50
95+95=
h= 190
and to write this as a linear equation we write this
( h-t=a)
(190-50-45 = 95)
190
50
140
-45

n(x)=−1−x+4 when x=−2,0, and 5
Answer:
-2
Step-by-step explanation:
n(-2) = -1 - (-2) + 4 = -1 + 2 + 4 = -1 + 6 = 5
( - 1 , 6 one has +sign and other -sign. So different sign mean, we have subtract and the sign of the result will be the bigger number's sign. Here bigger number [6] is +. So, result is 5)
n(0) = -1 - 0 + 4 = -1 + 4 = 3
n(5) = - 1 - 5 + 4 = -6 + 4 = -2
( -6 , 4 one has +sign and other -sign. So different sign mean, we have subtract and the sign of the result will be the bigger number's sign. Here bigger number [-6] is -. So, result is -2)

The two forms of equations are identity equations and conditional equations.
By substituting the value of x=3, then we get 23.
What is meant by an equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.
The two forms of equations are identity equations and conditional equations. All feasible values of the variables share the same identity. Only specific instances where the values of the variables coincide can result in the truth of a conditional equation. Two phrases exists connected into one by utilizing the equals sign ("=").
Let the equation be 2x² + 5
Substitute the value of x = 3, then we get

Solve the inequality for x. 7x > 42
Answer: x > 6
Step-by-step explanation: Since x is being multiplied by 7,
we divide by 7 on both sides of the inequality to get x > 6.
Now you should write your answer in set notation.
So we have {x: x > 6} which means that
any number greater than 6 is a solution.

Factor the trinomial.
x^2-16x+48
Answer:
(x - 4)(x - 12)
Step-by-step explanation:
Given
x² - 16x + 48
Consider the factors of the constant term (+ 48) which sum to give the coefficient of the x- term (- 16)
The factors are - 4 and - 12, since
- 4 × - 12 = + 48 and - 4 - 12 = - 16 , thus
x² - 16x + 48 = (x - 4)(x - 12)
Answer:
the correct option is (x-4)(x-12)
Step by Step explanation:-
x^2-16x+48
x^2-12x-4x+48
by taking the common factor out,
x(x-12)-4(x-12)
(x-4)(x-12)

What is prime factorization?Factorization is expressing a mathematical quantity in terms of multiples of smaller units of similar quantities.
For an integer, factorization is decomposition of that integer in terms of smaller integers which when multiplied with each other give back that considered number. Those composing integers are called factors of that considered integers.
The Prime factorization is when all those factors are prime numbers, prime factorization expresses an integer in terms of multiples of prime numbers.
Prime factorization is unique for each integer.

Answer:
(3x + 5) + (x +3) = 180 sum of angles on a
straight line
3x + 5 + x + 3 = 180
3x + x + 5 + 3 = 180
4x + 8 = 180
4x = 180 - 8
x = 172/4
= 43
The angles 3x + 5 and x + 3 are
3x + 5 = 3(43) + 5 = 129 + 5 = 134
