Please help me subject math

il brainliest if you answer correctly

Step-by-step explanation:

8 + (-4) = 4

bcoz positive + negative you need to subtract it and copy the sign for the highest number

-5 + (-5) = - 10

bcoz of the its same negative you need to add

12 + 14 =26

-2/3 + - 5/6 = - 3/2

first you need to find the LCD and the lcd of 2 and 3 is 6 simplify it become - 4/6 + - 5/6 = - 9/6 find the GCF of 9 and 6 is 3 so - 9/6 divide by 3/3 is - 3/2

(8) (-4) = - 32

bcoz positive times negative is negative

(13) (7) = 91

kts positive coz they are both positive

(-9) (-12) = 108

its positive bcoz negative times negative is positive

(1/2) (2/5) = 1/5

bcoz 1/2 (1/5) = 2/10 find the GCF and its 2. so 2/10 ÷ 2/2 =1/5

(-3/8) (3/4) = - 9/32

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76

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.
