Answer:
infinite solutions
Step-by-step explanation:
-3v-2=-2-8v+5v
Combine like terms
-3v-2 = -2 -3v
Add 3v to each side
-3v-2+3v = -2 -3v+3v
-2 = -2
Since this is always a true statement, there are infinite solutions
What are the answer choices in the drop down?
Answer:
(2,15)
Step-by-step explanation:
2 times 7 is 14 not 15
5 times 7 is 35
6 times 7 is 42
8 times 7 is 54
So factor
use reverse distributiver property
ab+ac=a(b+c) or
ab-ac=a(b-c)
so we need to find a
find the common factors of the variables
4=2 times 2
8=2 times 2 times 2
common is 2 times 2=4
so 4 is a factor of both
so
4x-8=(4)x-(4)2=(4)(x-2)
4(x-2) is the answer
Answer:
The side length of the square region is about 181,166 kilometres.
Step-by-step explanation:
population density = no. of people / area of region
given
population = 200,000
population density = 1650 people per square kilometers
1650 = 200,000/area of region
=> area of region = 1650*200,000 = 330,000,000
given that region is square in shape
area of square = side^2
side^2 = 330,000,000
side =
The side length of the square region is about 181,166 kilometres.
