1/2 + 2/5 = 5/10 + 4/10 = 9/10
Answer:
y = 8x
Step-by-step explanation:
When the number of people increased by 10, the caterer charged an additional $80. Therefore, we estimate that the cost per person is $8. In order to verify:
$8/person * 15 people = $120. True. $8/person * 25 people = $200. True.
Therefore, if we let x represent the number of people being cater for and y represent the cost, the equation to model the situation is simply y = 8x.

Answer:
4 cups of mayonnaise.
Step-by-step explanation:
The ratio of the amount of pecans comparing reality and the recipe is:
1 : 3/8
= 1/(3/8)
= 8/3
Hence, to find the amount of mayonnaise that should be added:
8/3 * 3/2
= 8/2
= 4 cups
Hope this helped!
Answer:
240 
12.5p + 65
14 
p
Step-by-step explanation:
I'll explain the equation in different parts
12.5p - Since the number of times he visits is unknown, it has to be a variable. With each visit, however, he earns 12.5 points.
65 - This is a set value that remains constant
240 - Since he needs AT LEAST 240 points, he needs 240 points or more to get his free ticket
As for solving the equation just use properties of equality
240 12.5p + 65
175 12.5p
14 p
The original side length was 12m therefore the perimeter was 36m. 12/4 is 3 so the perimeter is now 9, and the difference between them is 27.
