When a number is decreased by 54%, the result is 28. What is the original number to
the nearest tenth?

x = 60.9

Step-by-step explanation:

Let x represent the number

x - 54%x = 28

x - 0.54x = 28

0.46x = 28

Divide both sides by 0.46(coefficient of x)

x = 28/0.46

x = 60.86

to the nearest tenth

x = 60.9

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
