In 3 years, Dianna will be 4 times as old as she was 33 years ago. How old is Dianna now? Choose the most logical value for the

uranmaximum [27]

Answer:

45 years old

Step-by-step explanation:

Suppose Dianna age 33 years ago = x

Dianna age today = x + 33

Dianna age after 3 years = (x + 33) + 3

In 3 years, Dianna will be 4 times as old as she was 33 years ago

Equation

4x = (x+33) + 3

4x = x + 36

4x - x = 36

3x = 36

x = 36/3

x = 12

Dianna age today = x + 33 = 12 + 33 = 45

Diana is 45 years old.
