Evaluate 6t - 20-32u when t = 6 and u = 1/5

48/5

Step-by-step explanation:

6t - 20-32u

Let t = 6 and u = 1/5

6*6 - 20 - 32 (1/5)

Multiply

36 - 20 - 32/5

16 - 32/5

Get a common denominator

80/5 - 32/5

48/5

48/5 = 9 4/5

Step-by-step explanation:

first substitute the variable

6 (6) - 20-32 (1/5)

36-20-32/5

16-32/5

get the both numbers to have the same denominator

16 times 5/5 = 80/5

now subtract the both numbers

80/5-32/5 = 48/5

48/5 = 9 4/5
