Question

Just checking if the two questions are correct

Answer 1

63. The right answers are (a) y < 0 and (e) |y| > 1

64. Yes, you're right, answer is A. 7 1/5.

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...

`9 (3)/(5) + 4 (4)/(5) = 13 (7)/(5) = 14 (2)/(5)`

Then we split it into two equal buckets, we get...

`(14 (2)/(5) )/(2) = 7 (1)/(5)`

Answer is then A.
