1)a customer buys 2 shirts and pair athletic shoes. The shirts are priced the same. The customer spends a total of $95 .Write an equation to find the price of each shirt. 2) mark bought a pair of dress slacks a pair of dress shoes and a blazer. he spent $300. Write and solve an equation to find the cost of the blazel

a.

b.

Step-by-step explanation:

a. let s denote shirts and a denote athletic shoes.  given that the shirts are priced the same and that the total amount spent was $95.

#The price of each shirt can be calculated using the expression;

Hence, the price of each shirt is obtained using

b. First we have to understand that slacks and shoes have to be bought in pairs as a single unit but a pair of blazer is 2 units.

Let a denote the slacks, s shoes and b the blazer.

#Therefore our expression will be:

Hence, the price of each blazer is calculated using the expression

45

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.
