Answer:
Emily: 13, Peter: 9, Joshua: 18
Step-by-step explanation:
Emily = x
Peter = Emily - 4 = x - 4
Joshua = 2(Peter) = 2(x - 4)
Total = 40 = Emily + Peter + Joshua = (x) + (x - 4) + 2(x - 4)
40 = 2x - 4 + 2x -8
40 = 4x - 4 - 8
40 = 4x - 12
52 = 4x
x = 13
Emily = 13
Peter = 13 - 4 = 9
Joshua = 2(13 - 4) = 2(9) = 18
13 + 9 +18 = 40
Answer:
30,290,000 people
Step-by-step explanation:
The question is asking if the trend continues from the PREVIOUS year, so we would find the 30% of 23,300,000
23,300,000/100 = 233,000 = 1%
233,000 x 30 = 6,990,000
23,300,000 = 6,990,000 = 30,290,000
Y/3=12 should be y=63 because 63/3=12
Answer:

Answer:
The lines are parallel, and their slope is 1/3.
Step-by-step explanation:
Slope = Rise/Run
Rise tells us the distance between the two points on the y-axis and the run tells us the distance between the two points on the x-axis.
For Line 1, the rise is one unit and the run is three units. Therefore, the slope is 1/3.
For Line 2, the rise is one unit and the run is three units. Therefore, the slope is also 1/3.
Hope this helps!
