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
7.9-5.1=2.8 0.2+0.8=1 2.8 x 1=2.8

Answer:
x = 14 and x = - 7
Step-by-step explanation:
Not that + (- ) = -
(a)
x + (- 4) = 10, that is
x - 4 = 10 ( add 4 to both sides )
x = 14
(b)
2x - 10 = - 24 ( add 10 to both sides )
2x = - 14 ( divide both sides by 2 )
x = - 7
Answer:
1997
Step-by-step explanation:
999^2 = 999 x 999 = 998,001
998 ^ 2 = 998 x 998 = 996,004
998,001 - 996, 004 = 1997
