Alison has $1.60 worth of nickels and dimes in her coin purse. she has 11 more nickels than dimes. how many of each coin does she have? enter your answers in the boxes. and

Let the number of nickles be x and the number of dimes be y, so that means

0.05x + 0.1y=1.6

5x+10y=160...1

x=y+11...2

Put 2 into 1 that would give you

5(y+11)+10y=160

5y+55+10y=160

15y=160-55=105

y=105/15=7

x=7+11=18

So she has 18 nickels and 7 dimes

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.
