In order to get the average rate you should do the y2-y1/x2-x1 formula. lets see our points are (5,-2)(9,14).. so our formula should be filled like 14+2/9-5, now subtract or add to get 16/4 now divide to get positive 4..
Hope this helps
Answer:
Susan has suggested a correct method to calculate the amount of money
Step-by-step explanation:
Here we must check what each person is calculating. First, we consider Susan's method. She has suggested that we multiply the cost per soda, that is dollars/soda by the number of sodas required, we get the total cost.
Assuming that 18 sodas are required and each costs $0.20, the total cost according to Susan is $3.60.
John suggests we divide the cost of a 12 pack of soda by the number of sodas required. Considering a 12 pack of soda costs $12 and the same amount of sodas, 18, are required, we get that each soda costs $0.66.
Looking at these answers, we see that Susan has suggested a correct method to calculate the amount of money needed to buy a number of sodas. John has suggested the amount each person would have to contribute if everyone at the party was trying to buy a 12-pack of soda; regardless of whether more or less than a 12-pack is required.
The original price of the item will be $ 480.When there is 75% off on the original price.
<h3>What is the percentage?</h3>
The quantity of anything is stated as though it were a fraction of a hundred. A fraction of 100 can be used to express the ratio.
The right question is
"Joyce saved $120 on an item that was 75 % off. What was the original price?"
Given data;
% off = 75
Amount saved $120
Let the original price of the item is x
75 % of x + $120 = x
0.75x+ 120 =x
0.25 x =120
x=120/0.25
x=480
Hence, the original price of the item will be $ 480.

Answer:
you might’ve already answered this but it’s 65
Step-by-step explanation:
the two sides in a triangle have to be congruent so if one angle is 65, the other has to be 65 too :)
