As an algebraic term: x-4
16
20% = 1/54 + 4 + 4 + 4 + 4 = 2020 decreased by 20% is 16, therefore the answer is 20
60
best loving answer is 4 over 7
56 decreased by 4 is 52.
A number decreased by 4 is n-4
When 3 times a number is decreased by 4 the result is 17. what is the number?
Either 2*(n-4) = 2n - 8 or 2n - 4 It depends on whether the "twice" operates on "the number decreased by 4" or "the number".
x - 2 = 7 + x/4 4x - 8 = 28 + x 3x = 36 x = 12
The phrase "4 decreased by a number x" means that you are subtracting some number from the number 4, but you do not know what number you are subtracting. The number x is an unknown, that you are trying to find out.it means:4 - x
7-x=4
if the quotient of -20 and 4 is decreased by 3
The number is 4
n - 10
Then the number is 20.5
Then the number is 20
