Assumption: x x

is the number on which operations to be carried out.

#Using given arguments

x−35=.8x x−35=.8x .2x=35 .2x=35 x=35/.2 x=35/.2 x=175 x=175

#Now, we have to find four-fifth of this number and that would be:

(4/5)x=.8x (4/5)x=.8x

That will be same as

x−35 x−35 : x−35=175–35=140 x−35=175–35=140

So, 140 is the solution.

When 25 is subtracted from 4 times a certain number, the result is 59. What is the number?

Let n = the unknown number.

Four (4) times the unknown number n is 4n.

Twenty-five (25) subtracted from 4n is 4n - 25.

Therefore, "When 25 is subtracted from 4 times a certain number (n), the result is 59," can be translated mathematically to give us the following equation to be solved for n:

4n - 25 = 59

Begin solving this equation by isolating n on the left side by adding 25 to both sides and then simplify as follows:

4n - 25 + 25 = 59 + 25

4n + 0 = 84 4n = 84

Now, divide both sides by 4 and then simplify as follows:

(4n)/4 = 84/4 (4/4)n = 21 (1)n = 21 n = 21 CHECK: 4n - 25 = 59 4(21) - 25 = 59 84 - 25 =
