Answer:
both 125° and the 5x+30 are congruent to eachother. therefore you can go
5x+30=125
subtract 30 from both sides.
5x=95
then divide both sides by 5
x=19
The population of the group in 2019 is 2,134,000 people
Let P represent the population in thousands of people in the year t after 2011
Given the equation:

a) The population of the group in 2019, that is t = 8(2019 - 2011):

b) The population of the group in 2029, that is t = 18(2029 - 2011):

The population of the group in 2019 is 2,134,000 people

Mx - y
5x-y
5(3)-y
15-y
15-8 = 7
7 is your answer.
Answer:
B 3x+2
Step-by-step explanation:
perimiter=2L+2W
P=2(L+W)
if x=width then
P=2(L+x)
P=8x+8
hmm
8x+8=2(L+x)
distribute
8x+8=2L+2x
minus 2x both sides
6x+8=2L
divide both sides by 2
3x+4=L
the length is 3x+4
B is answer
I can't understand what you wanted with the second question (or if that is even a question), but the answer to the first one is 42.
