Answer:
I agree with Claire's representation. Sea level is considered as zero, going up in the number line is positive and going down in the number line is negative.
The location 10 feet above sea level is correct. We have to count 10 spaces going upwards from zero. This location is represented by the integer 10.
The location 10 feet below sea level is correct. We have to count 10 spaces going downwards from zero. This location is represented by the integer -10.
Step-by-step explanation:
The attached picture shows two points:
The red point represents 10 feet above sea level. (Integer: 10)
The blue point represents 10 feet below sea level. (Integer: -10)
Sea level is zero.
Slope= (-4-2)/(1-(-1)) = -6/2=-3 so the only answer choice with the slope as -3 is A, and that is your answer
So,
The sporting goods store is offering a discount of 40%.
20% of Rocco's money equaled the price of the golf club after the 40% discount.
After the 40% discount, the golf club was $48.
Therefore, 20% of Rocco's money was $48: the amount he spent on the golf club.
Multiply 20% by 5 to get 100%.
48 * 5 = 240
Rocco had $240 in his savings account before buying the putter.
If you want to keep it technical, the normal “/unit rate” for running is minutes per mile. You can use dimensional analysis like I did below to find the answer. You should get 11.45 min/mile or about 11 min 25 sec per mile
