Evaluate the expression for the given value of the variable 9 | 9 -8x | = 2x + 3
Gala2k [10]

Steps to solve:

9|9 - 8x| = 2x + 3

~Divide 9 to both sides

|9 - 8x| = 2/9x + 1/3

~Solve absolute value (part one)

|9 - 8x| = 2/9x + 1/3

-74/9x + 9 = 1/3 (Subtracted 2/9x to both sides)

-74/9x = -26/3 (Subtracted 9 to both sides)

x = 39/37 (Multiplied 37/39 to both sides)

~Solve absolute value (part two)

|9 - 8x| = -(2/9x + 1/3)

|9 - 8x| = -2/9x - 1/3 (Distributed negative sign to left side)

-70/9x + 9 = 11/3 (Added 2/9x to both sides)

-70/9x = -28/3 (Subtracted 9 to both sides)

x = 6/5 (Multiplied 9/-70 to both sides)

Therefore, the solutions are x = 39/37 and x = 6/5

Best of Luck!

A jet travels 584 miles in 4 hours. At this rate how far could the jet fly in 13 hours?what is the rate of speed of the jet
ankoles [38]

Answer:

The speed at which jet travel is 44.92 miles per hour

The distance cover at 44.92 mph is 583.96 miles  .

Step-by-step explanation:

Given as :

The distance cover by jet = d = 584 miles

The time taken b the jet to cover 584 miles = t = 13 hours

Let The speed at which jet travel = s

So, Speed = \dfrac{\textrm distance}{\textrm time}

or, s = \dfrac{\textrm d}{\textrm t}

Or, s = \frac{584}{13}

∴   s = 44.92 mph

So ,  The speed at which jet travel = s = 44.92 miles per hour

Now, At The speed of 44.92 mph

Let The distance cover at this speed = d' miles

And for the distance of d' , the time taken= 13 hours

Now, Distance = Speed × Time

So, d' = 44.92 mph × 13

Or, d' = 583.96 miles

So, the distance cover at 44.92 mph = d' = 583.96 miles

Hence  The speed at which jet travel is 44.92 miles per hour

And The distance cover at 44.92 mph is 583.96 miles  . Answer
