Order of operations in a simplified version is PEMDAS, which parenthesis, exponents, multiplication/division, addition/subtraction. so in your equation, 180 + (6-2), you start with what's inside the parenthesis to get 180 + 4. then skip MD bc there's no multiplication or division and move to AS. there is addition, so do addition. so your answer would be 184. however, the associative property is applicable here, so using PEMDAS is not required.
Answer:
What are you gonna do is across the x
Step-by-step explanation:
Answer:
The length of the shortest piece is 11 inches. The length of the medium piece is 14 inches. The length of the longest piece is 20 inches.
Step-by-step explanation:
Ok, so we have a long sandwich of 45 inches that will be divided in 3, giving us the following formula (x = shortest, y = medium, z=longest):
x + y + z = 45
Then we have middle piece (y) is 3 inches longer than the smallest (x):
y = x + 3
And the shortest piece (x) is 9 inches shorter than the longest (z):
x = z - 9 or z = x + 9
Let's place the found values of y and z in the first equation:
x + y + z = 45
x + (x + 3) + (x + 9) = 45
3x + 12 = 45
3x = 33
x = 11
So, x = 11, y = 14 and z = 20. (11 + 14 + 20 = 45).
