What is the value of 8(15-4)/4^2-5

kolbaska11 [484]

Answer: 0.5

Step-by-step explanation:

Android calculator accepts the above question via copy and paste, and gives 0.5

The point of this question is to try to discover whether or not you know what the expression means.

Rewriting it as (8(15-4)/(4×4)) - 5 would show that you know the meaning. You can check that by feeding it into the calculator as well.

Four more than three times n equals -5

Verizon [17]

3n+4=-5

do the opposite of adding 4. this means you have to subtract 4 from 4. whatever you do to the problem, you must do to the answer. now subtract 4 from -5.

-5-4=-9

since 4-4=0, we can take 4 out of the equation. now you have:

3n=-9

now divide -9 by 3

-9/3=-3

n=-3

hope this helps :)
