Here we have , A prepaid phone card has a balance of $22.40 remaining. Given that it costs $0.035 per minute . We need to find an equation represents the number of minutes, m, you may talk using the card . Let's find out :
Total balance = $22.40
It costs $0.035 for one minute of call . Let's suppose that with balance $22.40 we can talk for m minutes . So equation will be :
⇒
⇒
⇒
Therefore , an equation represents the number of minutes, m, you may talk using the card is . Correct option D) .

Answer:
Step-by-step explanation:
Let denote the length of the missing side. Since and share one vertex and , these triangles are similar. This means that:
We now multiply both sides by and solve the equation:
So we now simply get:
the factors and prime factorization of 14 and 28. (The biggest common factor number is the GCF number) So the greatest common factor 14 and 28 is 14.Jul
