Answer: b. 2x = 30
Step-by-step explanation:
Given : <u>30 states</u> joined the United States between 1776 and 1849
and <u>x states</u> joined between 1850 and 1900 .
If the number of states that joined the United States between 1776 and 1849 is twice the number of states that joined between 1850 and 1900.
i.e. No. of states joined the United States between 1776 and 1849= 2 (No. of states that joined between 1850 and 1900)
i.e . 30= 2(x) [Substitute the values]
i.e . 2x=30
Hence, the true equation : 2x=30

Step-by-step explanation:
Answer:
Perimeter 18.8
area 15
Step-by-step explanation:
Use pythageriums theorem
6^2 + 5^2 = c^2
I found the sides by counting squares
6^2 + 5^2 = 61
square root it to find the answer
7.8 is the missing side so now add it all together
7.8+6+5= 18.8
to find the area do 6 x 5/ 2
so the answer is 15
Answer: 19200 years
Step-by-step explanation:
The fossil in the above question has aged for 3.3 half lives. Since the half life of a fossil is given as 5730 years, the age of the fossil will be given as:
= 5730 years × 3.3333333
= 19200 years
Therefore, the age of the fossil is 19200 years.
