Sharon can buy cards in boxes of 12 and stamps in packages of 20 what is the least number of boxes of cards she should buy?
-Dominant- [34]

The least number of boxes Sharon should buy is 5 boxes.

Step-by-step explanation:

Given,

Number of cards in box = 12

Number of stamps in packages = 20

We will find least common multiple of 12 and 20.

12 = 12,24,36,48,60,.....

20 = 20,40,60,80,....

The LCM of 12 and 20 is 60.

Now,

12 cards = 1 box

60 cards = \frac{60}{12}\ boxes

60 cards = 5 boxes

The least number of boxes Sharon should buy is 5 boxes.

Convert from Standard Form to Slope Intercept Form<br> 3x + 2y = 6
Ilia_Sergeevich [38]

Answer:

y = -3/2x + 3

General Formulas and Concepts:

<u>Algebra I</u>

Equality Properties

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

Standard Form:   3x + 2y = 6

<u>Step 2: Find slope-intercept form</u>

  1. Subtract 3x on both sides:          2y = 6 - 3x
  2. Divide both sides by 2:                y = 3 - 3/2x
  3. Rewrite:                                         y = -3/2x + 3

And we have our final answer!

Calcular la edades actuales de una madre y sus dos hijos sabiendo que hace 14 años la dad de la madre era 5
rodikova [14]

The present age of mother and her daughter respectively are; 40 and 10 years respectively.

<h3>How to Solve Algebra Word Problems?</h3>

Let x and y be the present age of mother and her daughter respectively.

Therefore;

x + y = 50

x = 50 − y     .....(1)

After 20 years, mother's age will be twice her daughter's age at the time. Thus;

x + 20 = 2(y + 20)

x − 2y = 20     .....(2)

Plugging eq 1 into eq 2 gives us;

50 − y − 2y = 20

3y = 30

y = 10

Thus;

x = 50 − 10

x = 40

Thus, the present age of mother and her daughter is 40 and 10 years respectively.

Translation of the question into English is;

The sum of the present ages of mother and her daughter is 50 years. After 20 years, mother's age will be twice her daughter's age at the time. Find their present ages.
