x/2 + x + x/3 = 8
Simplify both sides of the equation
x/2 + x +x/3 = 8
Simplify
11/6 x = 8
Multiply both sides by 6/11
(6/11)*(11/6 x ) = (6/11)*(8)
x = 48 / 11
decimal will be x = 4.36
-7(x-1)-3(x-4)
Distribute
(-7)(x)+(-7)(-1)+(-3)(x)+(-3)(-4)
= -7x+7+ -3x +12
Combine like terms
-7x+7+ -3x+12
= (-7x+ -3x ) + ( 7+12)
= -10x + 19
3(x-2)^2 -5(x-2)+3
Distribute
= 3x^2 + -12x+12+(-5)(x)+(-5)(-2)+3
= 3x^2 +-12x+12+ -5x +10 +3
Combine like terms
3x^2 + -12x+12+ - 5x+10 +3
(3x^2) + (-12x+ -5x ) + (12+10+3)
= 3x^2 + -17x + 25
= 3x^2 -17x+25
I hope that's help ! Please if you have question about all 3 just let me know .

The number of stamps that Mary received are 4s-6
"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C"
Given,
Stacy has s stamps.
Then, from the question it is clear that Dominic has 3s-6 stamps
So, the number of stamps that Mary received will be 3s-6 +s = 4s-6
Hence, option C is the correct option.

Answer:
Sometimes
Step-by-step explanation:
A Composite number is the number which is not prime except 1. Hence, it has factors other than 1 and itself.
GCF is a greatest common factor i.e. the greatest factor that divides two numbers.
The GCF of two numbers can be composite number.
Example:
GCF of 8 and 24 = 8 which is a composite number.
GCF of 6 and 21 = 3 which is not a composite number.
Thus, GCF two numbers is sometimes a composite number.
