Evaluate -x+4y when x=-4/5 and y=1/3. Write your answer as a fraction or mixed number in simplest form.
I don't know, I'm not good at math.
Well, evaluating the expression -x+4y with x=-4/5 and y=1/3 is like telling someone to balance a clown nose on their finger while riding a unicycle - it might seem a little tricky at first, but I'm here to help you find the answer!
Let's substitute the values of x=-4/5 and y=1/3 into the expression -x+4y. We get:
-(-4/5) + 4(1/3)
Now, let's work our magic with some calculations. Starting with the negation of the first term:
(4/5) + 4(1/3)
Multiplying 4 by 1/3 gives us:
(4/5) + 4/3
To add these fractions with different denominators, we need to find a common denominator. The least common multiple of 5 and 3 is 15, and now we can rewrite the fractions:
(12/15) + (20/15)
Adding the numerators, we get:
32/15
And voila! Our final answer is 32/15. It's as simple as finding a clown in a rubber chicken factory!
To evaluate -x + 4y with given values of x and y, substitute x = -4/5 and y = 1/3 into the expression.
So, we have:
-(-4/5) + 4(1/3)
To evaluate negative of -4/5, we multiply -4/5 by -1:
(4/5) + 4(1/3)
Now, let's simplify the expression further:
To find the sum of fractions, we first need to find a common denominator. The least common multiple (LCM) of 5 and 3 is 15. So, we'll rewrite the fractions with a denominator of 15:
(4/5) + 4 * (1/3) can be written as:
(4/5) + (4/3) * (5/5)
Now, we can add the fractions:
(4/5) + (20/15)
To add the fractions, they must have the same denominator. Since the denominators are already the same, we can add the numerators directly:
(4 + 20) / 15
Simplifying the numerator, we get:
24 / 15
Now, we want to write the answer as a fraction or a mixed number in simplest form.
To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor (GCD).
The GCD of 24 and 15 is 3. Dividing both numerator and denominator by 3, we get:
8 / 5
So, the final answer is 8/5.

well, just plug in the numbers!
-x+4y = -(-4/5)+4(1/3)
= 4/5 + 4/3
...
I assume that since you are apparently taking algebra, you can handle the fractions, no?
