Answer:
63. The right answers are (a) y < 0 and (e) |y| > 1
64. Yes, you're right, answer is A. 7 1/5.
Step-by-step explanation:
Question 63.
In x * y = z, we know that x is positive, that z is negative and we know the absolute value of x is greater than the absolute value of z.
How can a positive number (x) be turned in a negative number (z) through multiplication? By multiplying it by a negative number (y).
So, if y is negative...
we can safely say that y < 0 and that the |y| > 1.
We can say |y| > 1 because y can't equal 0 (because z > 0) and |y| can't be equal to 1 since |x| > |z|, if |y| = 1, then we'd have |x| = |z|.
Question 64.
You got your fractions addition right!
If we begin by calculating the total amount of onions the restaurant now has...
[tex]9 \frac{3}{5} + 4 \frac{4}{5} = 13 \frac{7}{5} = 14 \frac{2}{5}[/tex]
Then we split it into two equal buckets, we get...
[tex]\frac{14 \frac{2}{5} }{2} = 7 \frac{1}{5}[/tex]
Answer is then A.
