-5/6m = -60
m = ?

Answers

Step-by-step explanation:

Hey there!

Given;

-5/6m = -60

~ Multiply "6m" and "-60".

-5 = 6m*-60

-5 = -360m

~ Divide "-5" by "-360"

m = -5/-360

m = 1/72

Therefore, the value of "m" is 1/72.

A horticulturist wants to improve the soil quality in a garden by adding 120 pounds of nitrogen and 54 pounds of potassium. A pack of organic fertilizer contains 2 pounds of nitrogen and 3 pounds of potassium, and a pack of inorganic fertilizer contains 6 pounds of nitrogen and 2 pounds of potassium. How many packs of each type of fertilizer does the horticulturalist need to use? (Hint Write an equation for the total amount of nitrogen (120 pounds) obtained by adding the packs of both the fertilizers and another equation for the total amount of potassium (54 pounds) obtained by adding the packs of both the fertilizers.)

A organic fertilizer: 24 packs; inorganic fertilizer: 12 packs

B. organic fertilizer: 14 packs; inorganic fertilizer: 6 packs

C organic fertilizer: 15 packs; inorganic fertilizer: 8 packs

D. organic fertilizer: 9 packs; inorganic fertilizer: 17 packs

Е. organic fertilizer: 6 packs; inorganic fertilizer: 18 packs​

Answers

x and y are the packs of organic and inorganic fertilizer, respectively.

pounds of nitrogen added = 2x + 6y = 120

pounds of potassium added = 3x + 2y = 54

eliminate the y terms. subtract the first equation from 3 times the second equation.

9x + 6y = 162

-2x - 6y = -120

------------------

7x = 42

x = 6

y = 18

52. 3x+4y=24

Answers

Answer:

Step-by-step explanation:

  [1]    3x - 4y = -24

  [2]    -x - 16y = -52

Graphic Representation of the Equations :

   -4y + 3x = -24        -16y - x = -52  

 

Solve by Substitution :

// Solve equation [2] for the variable  x

 [2]    x = -16y + 52

// Plug this in for variable  x  in equation [1]

  [1]    3•(-16y+52) - 4y = -24

  [1]     - 52y = -180

// Solve equation [1] for the variable  y

  [1]    52y = 180

  [1]    y = 45/13

// By now we know this much :

   x = -16y+52

   y = 45/13

// Use the  y  value to solve for  x

   x = -16(45/13)+52 = -44/13

Solution :

{x,y} = {-44/13,45/13}

v=12500-2500h

Step-by-step explanation:

Ok so to create this equation all you need to do is look at what information is given. You start with 12500 gallons of water so we know our equation is going to have 12500 in it.

So far our equation would look like this v=12500

The next information we are given is that it is decreasing by 2500 every hour so we know that we are going to be subtracting 2500 based on how many hours have went by so our equation would then look like this.

v=12500-2500h

we can check this by plugging in some numbers to see if it works. So at Zero hours we should still be at 12500

v=12500-2500(0)

v=12500

Ok so we know that it works for zero, but we should check at least one more number. We know that after 3 hours we would of lost 7500 gallons of water so it should equal 12500-7500=5000 gallons. Lets check this in our equation

v=12500-2500(3)

v=12500-7500

v=5000 Gallons

Tony hangs lights in his back yard. The rule c=14f gives the number of lights, c, there are for each foot, f, of wire. How many lights are on 8 feet of wire?

Answers

Answer:

112 lights

Step-by-step explanation:

The rule c=14f gives the number of lights, c, there are for each foot, f, of wire.

We need to find the number of light on 8 feet of wire.

Put f = 8 in the given rule equation

c = 14 × 8

= 112

Hence, there are 112 lights on 8 feet of wire.

Equation of the Line: y = 1.25x + 5

Equation in Standard Form: 5x - 4y = -20

Step-by-step explanation:

y = mx + b

[tex]\frac{17.5 - 22.5}{10 - 14}[/tex] = [tex]\frac{-5}{-4}[/tex] = [tex]\frac{5}{4}[/tex] or 1.25

y = 1.25x + 5

Ax + By = C  (A must be positive, and no fractions or decimals)

y = 1.25x + 5

-1.25x + y = 5
