Answer:
<h2>
6 1/2 lbs </h2>
Step-by-step explanation:
Given the weight of granite to be 74 26/36 lbs,
Weight of quartz is 81 9/40 lbs.
To know how much more quartz weight than the granite, we will take the difference between the weight of quartz and granite as shown.
Weight of quartz - Weight of granite
= 81 9/40 - 74 26/36
= 3,249/40 - 2690/36
= (29, 241 - 26,900)/360
= 2,341/360
= 6 181/360
≈ 6 1/2 lbs
quartz weighs approximately 6 1/2 lbs much more than granite

Answer:
A) |-6| + |3|
Step-by-step explanation:
Since the y-coordinates are the same, we need to find the distance between -6 and 3. This would thus be equal to |-6|+|3| making A the correct answer.
