Answer:
2/5
Step-by-step explanation:
There are 20 fish, 8 of which are small and blue. Therefore, the probability of randomly selecting a small blue fish is 8/20 = 2/5.
Answer: 4.2*w + 7*x + 5.4
Step-by-step explanation:
Here we need to remember how the product of different signs works, here is the rule:
(+)*(+) = (+)
(+)*(-) = (-)
(-)*(+) = (-)
(-)*(-) = (+)
Now we want to distribute the negative sign in the equation:
"-(-4.2w-7x-5.4)"
We can write this as:
-(-4.2w-7x-5.4) = (-1)*(-4.2w-7x-5.4)
Now we can distribute the "-1"
Then we get:
(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4)
We have 3 cases where we need to use the "(-)*(-) = (+)" rule, then we get:
(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4) = 4.2*w + 7*x + 5.4
Not 100% sure if this is correct but the answer is X=-7/5.
Parentheses then exponents then multiply then divided then add then substract
