Answer:
48.983.
Step-by-step explanation:
(The parentheses are not balanced so I am assuming that there is a square parentheses at the end of the given expression).
Using order of operations (PEMDAS):
20.003 + [(30.1 + 5.75) - 6.87] Work out the inner parentheses first:
= 20.003 + [35.85 - 6.87] Now the outer parentheses:
= 20.003 + 28.98
= 48.983.
X - number of apple pies
(7-x) - number of peach pies
6x- pieces of an apple pie
7(7-x) - pieces of peach pie
6x+7(7-x)= 44
6x+49-7x=44
-x=-5
x=5
7-x=7-5=2
Answer: 5 apple pies and 2 peach pies.

Answer:
(10x+4x^2+13)
Step-by-step explanation: 10 and 3 do not have a variable therefore they go together (both being positive you add). 2x, 2x, and 6x have the same variable, being positive you add. 4x^2 is the only number with the x^2 variable and stays by itself due to no others.
Answer:
c.
Step-by-step explanation:
1. 5 2/3 = 5 4/6
a. 2 x 2 = 4
b. 3 x 2 = 6
2. 5 4/6 - 4 1/6 = 1 3/6 = 1 1/2 = a
a. 4/6 - 1/6 = 3/6 = 1/2
b. 5 - 4 = 1
c. a = 1 1/2
