Answer:
The scale factor is 2.
Step-by-step explanation:
Take the vertical sides of the 2 triangles.
Their length is 3 and 6 so the scale factor is 6/3 = 2.
Also we see than the horizontal lines are in the same ratio 4 : 2 = 2:1.
B + d = 274,000
b = d + 22,000
(d + 22,000) + d = 274,000
2d + 22,000 = 274,000
2d = 274,000 - 22,000
2d = 252,000
d = 252,000/2
d = 126,000 <=== number of deaths
b = d + 22,000
b = 126,000 + 22,000
b = 148,000 <=== number of births
