Distribute
3x+6>0
Subtract 6 from both sides
3x>-6
Divide both sides by 3
x>-2
Final answer: x>-2
5/49(x)<span> = 20/7
5x/49 = 20/7
</span>5x/49 × 49 = 20/7 <span>× 49
</span>5x = 140
5x / 5 <span> = 140 / 5
</span>x = 28
It is black just letting u know
So. 2/5 of the fish are surgeon fish. Meaning that 40% of the fish are surgeonfish. From that 40%, the 75% are yellow tangs. So the 75% of that 40% equals to 30% of all fish (since (3/4)*(2/5)=3/10)
So the aquarium has 30% OR 3/10 of its fish being yellow tangs
