Hello!
To solve this exercise, let's think a bit and choose the best option for each alternative.
<h2>(a) Karen's desk is about 3...</h2>
Well, a desk with 3mm or 3cm is too small, and with 3km is too big.
In this case, the best option is 3 meters (even though it's big, it's the best option).
<h2>(b) Dan's refrigerator has a mass of 80...</h2>
Usually, a refrigerator is heavy. So the best option is kilograms.
<h2>(c) The bucket holds about 5... of water.</h2>
5ml of water is too little, it fits in a spoon. The correct option is liters.
Answers:
a. meters
b. kilogr
Answer:
x=-1
Step-by-step explanation:
To solve this question, we use simple division:
So, there are
10 servings of 4/5 of a cup in 8 cups.
First solve the congruence 
. Euclid's algorithm shows
330 = 25 * 13 + 5
13 = 2 * 5 + 3
5 = 1 * 3 + 2
3 = 1 * 2 + 1
=> 1 = 127 * 13 - 5 * 330
=> 127 * 13 = 1 mod 330
so that 
is the inverse of 13 modulo 330. Then in the original congruence, multiplying both sides by 127 twice gives
Then any integer of the form 
is a solution to the congruence, where 
is any integer.
A) No, because 62 + 9 = 122
