Step-by-step explanation:

If you have 1,500 per package and you need to find how many you will need to get 30,000 all you have to do is divide 30,000 by 1,500 and you get 20 packages. So the final equation would be 30,000=1500(20)

Answer:

Step-by-step explanation:

In the left problem, you use the fact that the sum of the segment lengths is equal to the overall length.

  AC +CB = AB

  (3x -4) +(x -2) = 62

  4x -6 = 62 . . . . . collect terms

  4x = 68 . . . . . . . add 6

  x = 17 . . . . . . . . . . divide by 4

__

In the right problem, you use the fact that the sum of the angles is equal to the overall angle. Here, that overall angle is a linear angle, so measures 180°.

  ∠DFG +∠GFE = ∠DFE

  (5y +3) +(2y -5) = 180

  7y = 182 . . . . . . . . . . . . . . collect terms, add 2

  y = 26 . . . . . . . . . . . . . . . .divide by 7

Answer:

B.]2

Step-by-step explanation:

The required positive value of n is 2. Hence, option B is correct.

Important information:

It is given that m is inversely proportional to the square of n. So,

[tex]m\propto \dfrac{1}{n^2}[/tex]

[tex]m=\dfrac{k}{n^2}[/tex]           ...(i)

Where, k is the constant of proportionality.

Substitute m = 6 and n = 3 in the above equation.

[tex]6=\dfrac{k}{3^2}[/tex]

[tex]6=\dfrac{k}{9}[/tex]

[tex]6\times 9=k[/tex]

[tex]54=k[/tex]

Substitute this value in (i).

[tex]m=\dfrac{54}{n^2}[/tex]

Substitute m = 13.5 in the above equation.

[tex]13.5=\dfrac{54}{n^2}[/tex]

[tex]n^2=\dfrac{54}{13.5}[/tex]

[tex]n=\pm \sqrt{4}[/tex]

[tex]n=\pm 2[/tex]

Therefore, the required positive value of n is 2. Hence, option B is correct.

Answer:

x intercept is (3, 0).  y intercept is (0, -12).

Step-by-step explanation:

x intercept is when y = 0.  [f(x) = y]  So 0 = 4x - 12. Solving for x gives you a value of 3.  [12 = 4x; divide by 4]

y intercept is when x = 0.  So y = 4(0) - 12.  Solving for y gives you a value of  -12.  [y= 0 - 12; y = -12]

Step-by-step explanation:

Answer:

the answer is $12

Step-by-step explanation:

to get the answer you would multiply 18 by 2/3 or you can divide by 3 then multiply what you get from dividing by 3 by 2.

version 1: 18(2/3) = ?

              12

version 2: 18/3=?

                6   you want to multiply by to because that is 1/3 of the original price

               6(2) = 12

Either way you get the same answer. Hopes this helps

Answer:

option 2: [tex]\large \frac{10}{12}[/tex]

Step-by-step explanation:

when dividing fractions, you can actually multiply them together by the reciprocal of the second one. (reciprocal is just flipping the fraction)

so, [tex]\frac{2}{3}[/tex] ÷ [tex]\frac{4}{5}[/tex]

becomes [tex]\frac{2}{3} * \frac{5}{4}[/tex]

to multiply fractions together, just multiply the top and bottom.

2 * 5 = 10

3 * 4 = 12

so the answer would be [tex]\frac{10}{12}[/tex]

Answer:

1/6 cups

Step-by-step explanation:

5/6 /5 = 5/6 divided by 5

= 5/6 x 1/5

= 1/6

so your answer is 1/6 cups of baking soda per tablespoon of water

yw ;)

The rate for cups of baking soda per tablespoon of water is 1/6.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The mixture that he adds to the paint is made of 5/6 cup baking soda for every 5 tablespoons of water.

Hence, The rate for cups of baking soda per tablespoon of water is,

⇒ 5/6 ÷ 5

⇒ 5/6 × 1/5

⇒ 1/6
