Answer:
To solve this you would do the following:
We know her plan is $15/monthly, regardless of any additional texts/calls she makes.
If 1 minute = $.20 worth of money, we would simply multiply 30 (she made 30 minutes worth of calls) x $.20 ($.20 for each minute). The product is $6.
So, $15 + $6 = $21.
Unless the amount owed per text is mentioned and you forgot to include it in the title, you would not need to take this into consideration.
Answer: 2
16-8=8
10-2=8
16-8=10-2
✔️
Both now equal 8 which makes it true
In geometry proofs, we commonly use step-by-step logic to figure out the proof. This is commonly used in Computer Science for understanding how computers work, process, and store information(I speak from personal experience). This is also commonly used in Law. You use this in Law as a lawyer to deduce information using step-by-step logical processes and logic, otherwise it's just wishful thinking. So, Law also uses the same reasoning skills used in Geometry proofs.
Answer:
The point (0,4) doesn't make either equation true.
Step-by-step explanation:
Consider the equations.
and 
We need to determine the point (0,4) make either equation true.
Substitute x=0 and y=4 in
Which is false.
Substitute x=0 and y=4 in
Which is false.
Hence, the point (0,4) doesn't make either equation true.
