I believe it is D. Just ignore the 3 then subtract 2/7 from the 4/7, which is 2/7. Now put the 3 back and you'll have 3 4/7.
Put the values of x = 4 and y = -2 to the expression 5y² + 3xy - 2x.
Use PEMDAS:
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
AS Addition and Subtraction (left-to-right).

Answer:
None of these
Step-by-step explanation:



1/10(0.2)
=(1/10)(0.2/1)
=(1)(36028) / (10)(18014)
=0.02
Answer:
40.021
Step-by-step explanation:
Unlimited calls = $40
Text message = $0.021
NOTE:There is a difference between the value you gave for cost of text messages in the question and the values given in the group of answers. I will use $0.021 for cost of text messages since it is common to all answer choices.
Total cost = Cost of unlimited calls + cost of text messages
C = $40 + $0.021
= $40.021
Therefore, the equation which represent the total cost in dollars for a month is 40.021
A. 40.021
