Find a number that is not a solution to 3x-1>8 or 7-x>3

Answers

Answer 1

Answer:

Answer:

All of the numbers are solutions.

Step-by-step explanation:

Step 1: Solve for x in the first equation

$3x - 1 + 1 > 8 + 1$

$3x / 3 > 9 / 3$

$x > 3$

Step 2: Solve for x in the second equation

$7 - x - 7 > 3 - 7$

$-x / -1 > -4 / -1$

Since you divided by a negative, you must flip the sign.

$x < 4$

Step 3: Find the number

x > 3 and x < 4

Answer: All of the numbers are solutions.

change per week?

Answers

The average change per week is 3 cents per week if, over a 6-week period, the price of a gallon of gas increases by 18 cents.

What is the rate of change?

It is defined as the change in values of a dependent variable with respect to the independent variables.

It is given that:

Over a 6 week period, the price of a gallon of gas increased by 18 cents.

Let x be the average change per week.

The numerator, which is found at the top of the fraction number, is referred as the numerator, and the denominator, which is found at the bottom of the fractional number, is referred as the denominator.

The value of x can be calculated as follows:

x = 18/6

x = 3 cents per week

Thus, the average change per week is 3 cents per week if, over a 6-week period, the price of a gallon of gas increased by 18 cents.
