9 – 2k = 25 what is k

Mathematics

worty [1.4K]4 years ago

Answer:

k = - 8

Step-by-step explanation:

Subtract 9 from both sides to get the constants on one side and the variables on the other

9 - 2k = 25

- 2k = 25 - 9

Simplify

- 2k = 16

Divide by -2 on both sides to isolate the variable, then simplify once more.

- 2k/ -2 = 16/ -2

k = 16/ -2

k = -8

Answer:

      k = -8

Step-by-step explanation:

9 – 2k = 25

   - 2k  = 25 - 9

    -2k = 16

         k = 16 / -2

         k = -8

To make 3/4 pound it makes nuts how many pounds of cashews would you add to 1/8 pound them almonds and 1/4 pound of peanuts
GrogVix [38]

9514 1404 393

Answer:

  a.  3/8 lb of cashews

Step-by-step explanation:

The amount that needs to be added is the difference between the amount of mix wanted and the amount of mix provided by the given quantities of nuts.

  3/4 lb - (1/8 lb +1/4 lb) = (3/4 -1/4 -1/8) lb = (2/4 -1/8) lb = (4/8 -1/8) lb

  = 3/8 lb . . . . amount of cashews needed

Silver's gym charges a $65 sign-up fee and $50 per month for their membership. Solar Fitness charges a $20 sign up fee and $55 p
alexandr1967 [171]
65+50x = 55x + 20
-50x -50
65=5x+20
- 20 - 20
55=5x
55/5= 5x/5
11=x
The solution represents that it 11 months will make both gyms the exact same price.

A line that includes the point (1, 3) has a slope of -7. What is its equation in slope-intercept
Alex787 [66]

Answer:

y = -7x + 10

Step-by-step explanation:

Using a point slope form equation

y - y1 = m( x - x1)

Given

Point = ( 1 , 3)

Slope = -7

Insert the values into

y - y1 = m(x - x1)

x1 = 1

y1 = 3

y - 3 = m( x - 1)

m = -7

y - 3 = -7(x - 1)

Using a slope intercept form equation

y = mx + c

Open the bracket

y - 3 = -7x + 7

y = -7x + 7 + 3

y = -7x + 10

The equation of the line is

y = -7x + 10

Given the rectangle below, write a simplified expression that represents the perimeter and terms of x. Use your expression to so
Tatiana [17]

The expression representing the perimeter is 6x + 39

x = 3. 8

<h3>What is the perimeter?</h3>

The formula for perimeter of a rectangle is given as;

Perimeter = 2 ( length + width)

From the image shown, we have that:

  • length = 2x
  • width = x + 13

Now, let's substitute the value

Perimeter = 2 ( 2x + x + 13)

collect like terms

Perimeter = 2 ( 3x + 13)

Expand the bracket

Perimeter = 6x + 39

If perimeter = 62

62 = 6x + 39

6x = 62 - 39

6x = 23

x = 23/ 6

x = 3. 8

Thus, the expression representing the perimeter is 6x + 39
