Answer:

Erin has 7 pens and James as 28 pens.

Step-by-step explanation:

Let e = the number of Erin's pens

Let j = the number of James' pens

e + j = 35                          j = 4e

substitute in 4e for j in the first equation above.

e + j = 35

e + 4e = 35

5e = 35  Divide both sides by 5

e = 7  Plug 7 in for e in either equation above.

j = 4e

j = 4(7)

j = 28

Hey! pls help me with this question on angles. would really be appreciated. have a nice day.
Neko [114]

Using supplementary angles, it is found that the measures of the angles are given as follows:

  • m<a = 30º.
  • m<b = 90º.

<h3>What are supplementary angles?</h3>

Supplementary angles are two angles whose sum is of 180º.

An interior angle is supplementary with it's exterior angle, hence:

m<a + 150º = 180º -> m<a = 30º.

The sum of the three interior angles of a triangle is of 180º, hence:

30º + m<b + 60º = 180º

90º + m<b = 180º

m<b = 90º.
