I believe for the first part x would equal -2 and y would equal -1
hope this helps!
-2.1 + 0.3 - 1.7 - 0.4 = -3.9
answer
A. -3.9 lbs
Answer:
D) 21!
Step-by-step explanation:
So what we are dealing with here is some fractions that need to be made equal
Think about the fractions 1/2 and 2/4. They look different, right?
Well really, they are equal to another. All we need to do is simplify them!
If we divide the numerator and denominator (the top and bottom) of the fraction by, lets say, 2!
2 / 2 = 1
- -
4 / 2 = 2
And viola! It's been simplified down, and now we can see they are alike!
2 pieces of a pie cut in 4 pieces is the same as 1 piece of a pie cut in half!
(pro-tip, always try dividing a fraction by 2 first)
So now, using the same principal, we can solve this problem
By taking the denominators and dividing them like this:
35 / 5 = 7
We get 7! Now since we need to make these fractions equal, lets multiply the 7 we just got by the numerator of the second fraction, 3
7 x 3 = 21
So if we put the 21 over the 35, we get 21/35!
Thus, our answer is 21!
