Hi there,
2 (x +5) - 3 = -(2x + 1) + 1
2x + 10 - 3 = -2x - 1 + 1
2x + 10 - 3 = -2 - 1 + 1
2x + 7 = -2x
2x + 2x = -7
4x = -7
Hence, X= -7/4
Hope this helps :)

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.
Answer:
153 s
Step-by-step explanation:
Given:
The variation of height of a rocket above ground with time 't' is given as:
In order to reach the ground, the height will be 0 feet.
So, plugging in 0 for 'h' and solving for time 't', we get:
So, at time , the rocket is at the ground or it is its launch point. Then after 153 seconds, it will again reach the ground.
So, the time it take for the rocket to hit the ground is 153 s.
To find the average of a set of numbers, we need to add up all of the numbers and divide by the amount of numbers we added.
Finding the average:
total = 2.5 + 4.6 + 6.75 + 4.8
total = 18.65
number of values added together = 4
average = 18.65 / 4
average = 4.66
The average distance Isabella ran is 4.66 miles.
Hope this helps!! :)
