Answer:x=3
Step-by-step explanation:
Add 4 to both sides and get 3x=5+4
Simplify 5+4 to 9 and get 3x=9
Divide both sides by 3 and get x=9/3
Simplify 9/3 to 3 and get the answer x=3
The mode is whichever one has the most so the mode would be 7. And the range is the highest number to the lowest. So 9-4 which is 5
Answer:
a=2, b=5
Step-by-step explanation:
Let
n -----> the denominator
we have

Solve for n
That means -----> isolate the variable n
Multiply by n both sides

Divide by 3.5*10^4 both sides

therefore
a=2, b=5
The answer is 20
