Answer:

The answer is 1/4

Step-by-step explanation:

move all terms with variables to one side and you get this : 20n=5

divide the variable side by 20 so you are left with the variable by itself. then do the same to the other side. 5/20 is 1/4

Find all possible values of a and b in the figures
Ira Lisetskai [31]

Answer:

Step-by-step explanation:

The perimeters are equal, so

2a+2b = 4a+b

b = 2a

area of rectangle is between 80 and 100

80 < ab < 100

substitution

80 < a(2a) < 100

40 < a² < 50

√40 < a < √50

6.4 < a < 7.1

Since a is an integer, a = 7.

b = 2a = 14.
