Urpi tuvo que comprar 4 \,\frac{1}{6} pliegos de cartulina para la elaboración del panel decorativo.

La cantidad de cartulina que Urpi compró para la elaboración del panel decorativo es la cantidad utilizada de cartulina menos la cantidad inicial disponible:

x = 2\,\frac{1}{2} + 1\,\frac{1}{3} + \frac{5}{6} - \frac{1}{2}

x = 2 + \frac{1}{2} + 1 +\frac{1}{3} + \frac{5}{6} - \frac{1}{2}

x = 3 + \frac{1}{3} + \frac{5}{6}

x = 3 + \frac{7}{6}

x = 3 + 1 + \frac{1}{6}

x = 4 \,\frac{1}{6}

Urpi tuvo que comprar 4 \,\frac{1}{6} pliegos de cartulina para la elaboración del panel decorativo.

Write the equation of a line that is parallel to the line 2x - 3y = 5 and passes through the point (2, -1)
jek_recluse [69]

Answer:

The equation of the line is 2x - 3y = 7 ⇒ answer A

Step-by-step explanation:

* Lets revise the relation between the parallel lines

- If two lines are equal then their slopes are equal

- We can make an equation of a line by using its slope and

 a point on the line

- If the slope of the line is m and passing through the point (x1 , y1),

 then we can use this form [y - y1]/[x - x1] = m to find the equation

* Lets solve the problem

- The line is parallel to the line 2x - 3y = 5

∴ the slope of the line = the slope of the line 2x - 3y = 5

- Rearrange the terms of the equation to be in the form

  y = mx + c to find the slope of it

∵ 2x - 3y = 5 ⇒ subtract 2x from both sides

∴ -3y = 5 - 2x ⇒ divide two sides by -3

∴ y = 5/-3 - 2x/-3 ⇒ y = 2/3 x - 5/3

∴ The slop of the line is 2/3

∵ The line passes through point (2 , -1)

* Lets use the rule to find the equation of the line

∵ y - (-1)/x - 2 = 2/3

∴ y + 1/x - 2 = 2/3 ⇒ by using cross multiplication

∴ 3(y + 1) = 2(x - 2) ⇒ open the brackets

∴ 3y + 3 = 2x - 4 ⇒ put x an d y in one side

∴ 2x - 3y = 3 + 4

∴ 2x - 3y = 7

* The equation of the line is 2x - 3y = 7
