what is the vale of 4²-2(3÷5 + 1)?
A 8
B 1
C -16*
D -21
As written, I get none of the above.
Show your work, and we can check what's going on.
To get -16, the 2nd term must come out to -32, since
16-32 = -16
so its A
You are just guessing.
As Steve suggested, show your steps so we can see how you obtained either -16 or 8 as your answers
i got the answer now thanks for nothing
no problem. Feel free to stop by any time, but next time you need to ante up some work before we bother betting.
To find the value of the expression 4² - 2(3 ÷ 5 + 1), we need to follow the order of operations, which states that we should solve operations inside parentheses first, then any exponents, followed by multiplication and division from left to right, and finally addition and subtraction from left to right.
First, let's solve the operations inside the parentheses: 3 ÷ 5 + 1.
To divide 3 by 5, we get 0.6.
Then, we add 1 to 0.6, and we get 1.6.
Now, the expression becomes 4² - 2(1.6).
Next, we deal with the exponent: 4² means 4 raised to the power of 2, which is 16. So now we have 16 - 2(1.6).
Finally, we multiply 2 by 1.6, which gives us 3.2. So the expression becomes 16 - 3.2.
Now, subtract 3.2 from 16: 16 - 3.2 = 12.8.
Therefore, the value of the expression 4² - 2(3 ÷ 5 + 1) is 12.8.
Looking at the given answer choices, the closest option is C: -16. However, the correct value is actually positive, not negative, so the correct answer is not listed among the provided choices.
