Step-by-step explanation:
To do Order of Operations, we need to go with the order of the formula, PEMDAS.
P= Parenthesis
E= Exponents
M= Multiply (Whatever Comes First in Equation: M and D)
D= Divide
A= Addition (Whatever Comes First in Equation: A and S)
S= Subtraction
---------------------------------------------
So, we need to start with parenthesis, there aren't any, so we move on to Exponents.
There are no Exponents either, so we start with division, then multiplication.
(We always have to go left to right).
So,
-9 - 6 + <u>8 / -4</u> x -2
-9 - 6 + <u>-2 x -2</u>
-9 - 6 + 4
Our problem is:
-9 - 6 + 4
We do subtraction, then addition. (Left to Right)
<u>-9 - 6 </u>+ 4
<u>-15 + 4</u>
-11.
Therefore, the answer is -11.
(Corrected)
Lets solve for x.
0.8x = 50. - Remember that the jacket was 80% of the original price.
Thus, divide by x.
x = 50 / 0.8
x = 62.5
3/20 = 0.15
0.15 * 100 = 15
You would need to use 15 eggs for 100 pancakes.
We know that there are (4^9)^5 ⋅ 4^0 at the library, so we just need to simplify this to get the answer.
(4^9)^5 ⋅ 4^0
=(4^9)^5×1
=(4^9)^5
=4^9×5
=4^45. As a result, the total number of books at the library is 4^45 books at the library or B is the final answer. Hope it help!
Four times fifteen plus twenty in parentheses
idk if its correct though <span />
