Hello,
f(1)=-1.5
f(2)=-2*f(1)=-2*(-1.5)=3
Answer D
Answer:
Simplifying the expression:
we get 
Step-by-step explanation:
We need to simplify the expression: 
First we will solve terms inside the bracket

Converting mixed fraction
into improper fraction, we get: 
Replacing the term:

Now, taking LCM of: 5,3,4,2 we get 60
Now multiply 60 with each term inside the bracket

Now, combine like terms

Now, multiply all terms with 2

So, Simplifying the expression:
we get 
Answer
Yes
Explanation
I just know
90/3 parts of silver = 30 times multiplied by
tin = 12 × 30 = 360g
lead = 8 × 30 = 240g
12.5 / 23 = 0.5434 parts per metal
tin = 12 × 0.5434 = 6.5kg
lead = 8 × 0.5434 = 4.5kg
silver = 3 × 0.5434 = 1.5kg
Answer:
The number is 133.5
Step-by-step explanation:
Let the number = x
2/3 * x = 89 Multiply by 3
2x = 89 * 3 Combine
2x = 267 Divide by 2
x = 133.5
