Answer:

All real numbers are solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

7x− 3 = − 3 + 7x

Step 1: Simplify both sides of the equation.

7x − 3 = −3 + 7x

7x + −3 = −3 + 7x

7x − 3 = 7x − 3

Step 2: Subtract 7x from both sides.

7x− 3 −7x = 7x −3 −7x

−3 = −3

Step 3: Add 3 to both sides.

−3 + 3 = −3 + 3

Find the widest range of scores that you can get on a final exam in order to receive a grade of B for the class. Using interval

Drupady [299]

Answer:

Correct choice is B

Step-by-step explanation:

Let x% be your final test score, then the average of all test scores is

$\dfrac{96+77+74+x}{4}.$

Since you must have an average between 80% and 89%, then

$80\le \dfrac{96+77+74+x}{4}\le 89,\\ \\320\le 247+x\le 356,\\ \\73\le x\le 109.$

X is measured in percent, then the greatest value of x can be 100%. You get that

$73\%\le x\le 100%.$
