Please help me with this answer having a hard time
1 answer:
To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
In this problem we have double parentheses. Which one should we solve first? The answer to that is always the inner most ones:
13[ 6² ÷ (5² - 4²) + 9]
5² - 4²
^^^Here you will have to first take the square of both values
25 - 16
9
13[ 6² ÷ (9) + 9]
Now for the exponents
13[ 6² ÷ (9) + 9]
6²
36
13[ 36 ÷ 9 + 9]
Now for the division:
13[ 36 ÷ 9 + 9]
36 ÷ 9
4
13[ 4 + 9]
Now for the addition
13[ 4 + 9]
4 + 9
13
13[13]
Now for multiplication
169
Hope this helped!

Answer:
{ }
Step-by-step explanation:
There are no numbers that are both greater than 9 and less than 2. The expression describes the empty set.
C+T=127
--------------
2C+4=T
-----------
C+(2C+4)=127
3C+4=127
3C=123
C=41
------------------
When C=41,
41+T=127
T=127-41
T=86
------------------
Check answer:
86+41=127
