What value of x makes this equation true?
0.6 x -5 = 0.1 x + 7

0.6x-5=0.1x+7

(subtract 0.1 from both the sides)

0.5x - 5 = 7

0.5x = 12    (bring 5 to the other side, then add)

x = 12/0.5

Shift the decimals of both 12 and 0.5 to the right by 1 decimal place. (This is needed to convert 0.5 to 5, since long division must divide by a whole number.)

x = 120/5

x = 24

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
