I WILL MAKE YOU BRAINLESS WHOEVER HAS THE BEST EXPLAINATION Simplify the expression. 1.7 – 2.7 – 1.34 + 4.9 – 1.48
explain im lost

0.08

Step-by-step explanation:

1.7 – 2.7 – 1.34 + 4.9 – 1.48

 2.7

- 1.7       (subtract 1.7 from 2.7)

-1.0      [2.7 is greater than 1.7 and 2.7 is negative(in the ques) , therefore  1.0 is negative]

-1.0-1.34

we know that  (-) (-) is (+)

therefore add -1.34 with -1.0

   1.34

+  1.0

  -2.34 [since 1.34 is greater and it is negative]

-2.34+4.9

we know that (-)(+) is (-)

therefore subtract -2.34 from 4.9

  4.90  ← (we put zero so that we can subtract without getting confused)

-  2.34

  1.56 [1.56 is positive because 4.9 is greater and it is positive]

1.56-1.48

here, digit before the decimal point is same but  after decimal point .56 is greater than .48  therefore subtract 1.48 from 1.56

  1.56

-  1.48

  0.08

therefore,  1.7 – 2.7 – 1.34 + 4.9 – 1.48 = 0.08

hope it helps you!

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

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.
