Answer:
c. 8×4-(2×3+8)÷2
Step-by-step explanation:
Using the rules of BODMAS,
B stands for bracket
O stands for Order
D stands for Division
M stands for Multiplication
A stands for Addition
S stands for Subtraction
8×4-(2×3+8)÷2
Now using this rule we will first of all open the bracket, In the bracket we multiply then add
8 × 4 - (6 +8) ÷ 2
8 × 4 - 14 ÷ 2
Still applying the rule, we divide 14 by 2 to give us 7
8 × 4 - 7
Then, still applying the rule, we multiply 8 by 4 which will give us 32
32 - 7
Then we finally subtract 7 from 32 to give us 25
32 - 7 = 25
So the expression; 8×4-(2×3+8)÷2 is equivalent to 25
n = 15
Use one of the four fundamental arithmetic operations to add, subtract, multiply, or divide two or more integers. For challenging computations, we use the PEMDAS approach.
Given five times n is equals to 45 less than twice the number of n.
hence,
5 * n = 2* n + 45
3* n = 45
n = 15
Therefore the value of the n in the given problem is 15.

Answer:
1.33313073483
Step-by-step explanation:
(can someone please help me I'm desperate)
Using a calculator, 1200/180 = 6.67 approximately
If you use long division, then you'll get what you see in the diagram below
The 6's go on forever after the decimal point, but if you round to two decimal places, then you'll get that approximate value of 6.67
---------------
If you want a remainder, then 1200/180 = 6 remainder 120
You can think of it like you having 1200 cookies and 180 friends. Each friend will get 6 whole cookies and there will be 120 left over as the remainder.
For this case we have that by power properties it is fulfilled:
Now, we can rewrite the expression as:
We also have by definition of properties of powers that:
So:
