You would get rid of the 2.5 by subtracting 2.5 on both sides, then the equation becomes
3x=3.6
solve for X by dividing 3 on both sides

Equations and inequalities!<br> solve for w <br> 11=253-w
Annette [7]

Answer:

w = 242

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

  • 11=-w + 253
  • -w + 253 = 11

Step 2: Subtract 253 from both sides.

  • -w + 253 - 253 = 11 - 253
  • -w = -242

Step 3: Divide both sides by -1.

  • \frac{-w}{-1}=\frac{-242}{-1}
  • w = 242

Step 4: Check if solution is correct.

  • 11 = 253 - (242)
  • 11 = 253 - 242
  • 11 = 11

Therefore, w = 242.

Have a lovely rest of your day/night.

What is the value of k such that 5x-2y=9 and 6x+ky=4 are perpendicular?
max2010maxim [7]

15

5x-2y=9......(1)

6x+ky=4......(2)

slope of eqn i= -5/-2

=5/2

slope of eqn ii = -6/k

since the line are perpendicular

5/2 * -6/k = -1

-30= -2k

k=15

The number of days ahead travelers purchase their airline tickets can be modeled by an exponential distribution with the average
agasfer [191]

Answer:P(x<10) =0

Step-by-step explanation:

M =1/μ

M= 1/15 =0.066667

X- Exp (0.066667)

Where: X is the random variable for number of days

P (X<x) = 1 - e^-mx

P(X - x) = 1 - e^-0.06666 x10

P(x<10) = 0
