1) C - You would look at a map to get to your friends house
2) B -(PEMDAS) order of operations, you subtract in that problem, it comes first
3) A - you add -3 to each side making 11 now 8

Answer from: madgiemiller2309

1. c. Follow a map

2. b.subtraction

3. a. addition

Step-by-step explanation:

2x + 3 = 11

The first step to take when solving this equation is to subtract three (3) from both-side of the equation

2x + 3 -3 = 11-3

2x = 8

The the next step to take in other to get the value of x is to divide both-side of the equation by 2

2x/2 = 8/2

(on the left hand-side of the equation, 2 will cancel out to leaving us with just x and on the right-hand side of the equation, we will divide 8 by 2 which will give us 4)

x = 4

3) 2x - 3 = 11

In this case, the first step to take while solving this equation, is to add 3 to both-side of the equation

That is;

2x - 3 + 3 = 11 + 3

2x = 14

Now, the next step to take in order to get the value of x is to divide both-side of the equation by 2

2x/2 = 14/2

(on the left-hand side of the equation, 2 will cancel out 2 leaving us with just x and on the right-hand side of the equation 14 will be divided by 2 which will give us 7)

x = 7

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.
