Answer:

x = 10

y = 6

Step-by-step explanation:

<u>Vertical Angle Theorem</u>:  When two straight lines intersect, the opposite vertical angles are always equal to each other.

⇒ m∠1 = m∠3   and   m∠2 = m∠4

⇒ m∠1 = m∠3

⇒ 10x = 100

⇒ x = 10

<u>Linear pair:</u>  Two adjacent angles which sum to 180°.

⇒ m∠1 + m∠2 = 180°

⇒ m∠3 + m∠4 = 180°

⇒ 100 + 10y + 20 = 180

⇒ 120 + 10y = 180

⇒ 10y = 60

⇒ y = 6

Mary has twice as many pencils as she has pens. Tom borrows a pen. Now, Mary has ten less pens than pencils. How many pencils do
I am Lyosha [343]
X - the number of pencils
y - the number of pens

She has twice as many pencils as she has pens.
x=2y

Tom borrows a pen, so she has y-1 pens. Now she has ten less pens than pencils.
x-10=y-1 \\&#10;x=y-1+10 \\&#10;x=y+9

Set 2y and y+9 equal to each other:
2y=y+9 \\&#10;2y-y=9 \\&#10;y=9
She has 9 pens.
