Answer:
Step-by-step explanation:
Given that,
(-10x - 7) - (3x - 10)
Note:
-×-=+
+×+=+
+×-=-
-×+=-
Then,
(-10x - 7) - (3x - 10)
Open bracket
-10x-7-3x+10
Collect like terms
-10x-3x-7+10
-13x+3
Then, the answer is -13x+3.
Answer:
3/10 of the aquarium are yellow tangs.
Step-by-step explanation:
Given that in an aquarium 2/5 of the fish or surgeonfish and of these, 3/4 are yellow tangs, to determine what fraction of all fish in the aquarium are yellow tangs the following calculation must be performed:
2/5 = 0.40
0.40 x 3/4 = X
1.20 / 4 = X
0.30 = X
0.30 = 3/10
Therefore 3/10 of the aquarium are yellow tangs.
