The algebraic expression for 25 less than a number ( d ) is ( d - 25 ). This indicates that you subtract 25 from the value of ( d ).
If you mean: cd which means c*d then it is 3.5*12.8 = 44.8
Replace each variable in the expression by its value and then find the value of the expression.
Technically is can be anything you want it to be since you did not equate this expression to any value.
To determine that the value of ( d ) is the same in both equations, you can isolate ( d ) in each equation and compare the resulting expressions. If both equations yield the same expression for ( d ) when simplified, then the value is confirmed to be the same. Additionally, substituting known values from either equation should yield consistent results for ( d ).

It is 138.
If there are d $1 bills their value is $1 × d, or d dollars.Each $5 bills is worth 5 times as much so if there are f bills their value is $5 × f, or 5f dollars.Thus the expression for the total would be d + 5f dollars.

36.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.5
c + d = 17.5 c - d = 12.3 c x d = 38.74 c/d = 5.73076923

to find the value of an expression, you need to
An equivalent expression.
You evaluate the expression !! :)
