Solution:
We have been asked to find the simplified expression of
Answer:
No, since when you multiply a number by 0, that means you are not adding that number to the sum which is 0. Since there is no addition going on, the answer is 0, so when you multiply any number by 0, the answer is 0.

Answer:
See below.
Step-by-step explanation:
The error is she reversed the direction of the inequality. The only time you do that is when multiplying an inequality by a <u>negative</u> number.
She should have done:
Answer:
x = 400 when y = 100
Step-by-step explanation:
This is a question in relation to direct variation.
y ∝
y = k
Given that, y = 45, x = 81. Then;
45 = k
45 = 9k
k =
k = 5
Thus the relationship among the variables is;
y = 5
If y = 100, then;
100 = 5
=
= 20
x =
x = 400
Therefore, x = 400 when y = 100.
