Answer:

x = 102

Step-by-step explanation:

In October, Greg and Thomas had the same amount of money in their savings accounts. In November, Greg deposited $120 into his ac
Minchanka [31]
If Greg deposited $120 into his account and Thomas increased his money by 20% and they still got the same amount in November, it means that $120 is 20% of their money in October.

120 = 20% * x (where x is the money in October)
120 = 20/100x
120 = 2/10x
120 = 1/5x            / * 5 (both sides)
x = 600

So each of them had $600 in October.

Doublecheck:

Greg's money = 600 + 120 = 720
Thomas' money = 600 + 20% * 600 = 600 + 120 = 720

So it's correct :)

PQ and QR are 2 sides of a regular 10-sided polygon
gladu [14]

Answer:

Step-by-step explanation:

Measure of inner angle of the n-sided polygon is

\frac{180(n-2)}{n}

~~~~~~~~~~~~~~

m∠PQR = \frac{180(10-2)}{10} = 144°

PQ = QR ⇒ m∠QPR = m∠QRP

<em>m∠PRQ =</em> ( 180° - 144° ) ÷ 2 = <em>18 </em>°
