Answer:
A. 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
Answer:
9 and 11
Step-by-step explanation:
First number = x -2
Second number = x
and 2x = 3(x-2) - 5
2x = 3x - 6 - 5
x = 11
first number = 11-2 = 9
Answer:
commutative property of multiplication
Step-by-step explanation:
The value of the product of the given equation remain the same while the order is reversed
The number sequence 4 × 6 = 6 × 4 is an example of the commutative property of multiplication
Reason:
The given number sentence is 4 × 6 = 6 × 4
Required: The property the number sentence is an example of (represent)
Solution:
The difference between the left and right expression is that the order of the
values being multiplied is changed or reversed (commute)
Therefore, the number sentence states that the value of the multiplication
of two variables remain equal when the places of variables are
interchanged as follows; a × b = b × a
a × b = b × a is an example of commutative property of multiplication
Therefore;
4 × 6 = 6 × 4 is an example of the commutative property of multiplication
This is a geometric sequence because each term is a constant multiple, called the common ratio, of the previous term. In this case the common ratio, noted as "r", is:
8/-2=-32/8=128/-32=r=-4
The first term is -2
Any geometric sequence can be expressed as:
a(n)=ar^(n-1), a=initial term, r=common ratio, n=term number.
Since we know r and a for this problem already we can say:
a(n)=-2(-4)^(n-1)
