1. Three pounds of M&M’s cost $7.50. At this rate, what is the cost of 7 pounds? 2. Three pounds of M&M’s cost $7.50. How many pounds can you buy with $50?

1. 17.50

2. 6

Step-by-step explanation:

1A: First you have to divide the cost by the three pounds to get the price per pound. Now that you have that answer you multiply it by 7 to get the price of 7 pounds.

2A: You can buy 6 pounds because if you multiply 7.5 x 6 you get 45 which you cannot add one more 7.50 so that is your final answer.

Hope this helps you ^^

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

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.
