Jeannie got a new pair of eye glasses. She was able to pay $15 at the time she received her glasses. She will pay $12 each month on the balance. The
original cost of the glasses was $87.
a. Let x represent the number of months needed to pay off the cost
of the glasses. Write an equation and explain how the equation
represents this situation.
b. How many months will it take Jeannie to pay for her glasses?
Explain how you know your answer is correct Jeannie got a new pair of eye glasses. She was able to pay $15 at the time
she received her glasses. She will pay $12 each month on the balance. The
original cost of the glasses was $87.

6 months, i used the equation from part a so i know it’s right

Step-by-step explanation:

a) 15 + 12x = 87

b) 12x = 87-15=72

72/12 = 6

how many players are there?

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
