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:Yessss
Step-by-step explanation:
y = 30 + 40x
x = 40 + 30y
x = 40 +30y
y = 40 + 30x
Answer:
y = 40 + 30x
Step-by-step explanation:
You dont know how many houses, so you put a variable for it. You have $40 in your wallet. Thats why y = 40 + 30x is your answer.
Answer: 8(3-2x)(x+5), -16x^2-56+120, x=-5, or x=3/2.
Step-by-step explanation:
First convert the multi fraction into multiplication: 8(3-2x)(x+5)
Then simplify: -16x^2-56+120
If you want, you can solve for x, which gets you x=-5, or x=3/2.
I hope this helps! :P
