in 1980 it was about 20%
in 1990 it was about 30%
about a 10% increase
in 2000 it was just under 40% so almost a 10% increase
so for estimating you can say it is increasing by about 10% every 10 years
so in 2010 you can estimate about 50% are unmarried
Answer:
Area of Triangle A = 4 cm²
Area of Rectangle = 24 cm²
Area of Triangle B = 4 cm²
Area of Trapezoid = 32 cm²
Step-by-step explanation:
The formula to find the area of a triangle is: 
The base (b) is 2 and the height (h) is 4.
Now multiply,
2 times 4 = 8
Then divide,
which equals 4.
So the area of Triangle A and B is 4 cm² because they are the same triangles.
The formula to find the area of a rectangle is: a times b.
a=6 and b=4
Multiply,
6 times 4 = 24
So the area of the rectangle is 24 cm²
The formula to find the area of a trapezoid is: 
A=6
B=10
H=4
So now,

6+10=16
16 divided by 2 is 8.
Last multiply,
8 times 4 is 32.
The area of the trapezoid is 32 cm²
Hope this helped! And have a great day!
Answer:
135
Step-by-step explanation:
I am not sure if you have to use the substitution method but I just did (600 - 60) then divided by 4
