Which of the following best describes the solution of the system of equations below?

Answers

Answer 1

Answer:

Step-by-step explanation:

-8x + y = -3..... (equ 1)

9x - y = 3.....(equ2)

y = 8x - 3

-y = -9x + 3(divide both sides by -1*)

hence ..y = 9x - 3

then write y = y in terms of x

which will give you 8x - 3 = 9x - 3

and solve for x which will be N/A

Solve the equation for x:
|3x - 2| = 5

Answers

Answer:

x = 1

Step-by-step explanation:

When there is an equation in absolute form like this |3x - 2| that means that there are no negative numbers or subtraction signs. Instead, such things are reversed, so the simplified equation is

3x + 2 = 5

So then we proceed as normal

3(1) + 2 = 5

3 + 2 = 5

5 = 5

On wends day 72% of the customers who bought gas at the gas station made additional purchases.There were 250 customers who bought gas. How many of the 250 customers made additional purchases
