the ratio of boys to girls is in a class 4:3. There are 35 students in the class. How many students are boys ?
What is the formula?​

Answer:

4x67€hus de tus nos cos

Answer: positive

Step-by-step explanation: because the bigger number is always going to be the answer

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

Answer:

Approximately 10 died every minute with a remainder of 12

Step-by-step explanation:

I divided 60 seconds by 612 because 60 seconds is one minute and i got 10 remainder 12

Answer:

perimeter you add all sides together:

5x+2 +5x+2 +x +8 +x+8

12x +20

and for Area you multiply:

(x + 8)(5x + 2)

5x^2 + 2x + 40x +16

5x^2 +42x +16

so your answer is the first one or "A"

Answer:

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

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.

Answer:

-62.9

Step-by-step explanation:

7.4= [tex]\frac{-t}{8.5}[/tex]

8.5 (7.4)=-t

62.9=-t

t=-62.9

Answer:

the answer is 5/6

Step-by-step explanation:

the company is not the first BFF to come to mr as default

the answer is 5/6. have a good day

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.

Hope it helps....

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}

Answer:

9.28 liters

Step-by-step explanation:

The unit rate is 1.6 liters per hour.

You multiply it by the number of hours

1.6 x 5.8 = 9.28

Answer:

9.28.

Step-by-step explanation:

We're trying to find out how much gas Luis uses in 5.8 hours. It states that Luis uses 1.6 liters of gasoline EACH HOUR. So, we just multiply 1.6 and 5.8.

Answer:

20% tip = $4.40; total = $26.4

Step-by-step explanation:

20 % = 0.20 ------> 22 * 0.20 = 20% of 22

20% of $22.00 = $4.40

total = $22.00 + $4.40

total = $26.40

Step-by-step explanation:

250 - 246 = 4

246 - 242 = 4

Since 250 is 2(mod 4), the negative value term is -2.

Answer:

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

times -4

5x - 4y = -20

Answer:

4/6
