2) The percentage of customers was measured to determine ratings. The food and decor can't be measured. Seating capacity is not a measurement variable.
3) The date of measurement is not mentioned
4) The measurement would have to be taken at restaurant obviously.
5) The measurments were taken to determine the ratings and decide the best restaurant

Answer:
<u>After a 75% increase, it would become</u>
x + 75%x = x + 0.75x = x(1 + 0.75) = 1.75x
<u>After a 50% decrease, it would become</u>
1.75x - 50%(1.75x) = 1.75x - 0.5(1.75x) = 1.75x - 0.875x = 0.875x = 
Because
is less than x, the new amount would be less than the original.
Answer:

Step-by-step explanation:
10 3/9 - 10 2/5
we need to convert mixed fractions to improper fractions


Now, we have 93/9 - 52/5
We need to equate the denominators, before subtracting them.




The result of 10 3/9- 10 2/5 is - 3/45
First convert 5 1/3 into a fraction which is 16/3.
16/3 divided by 7/8 is the same as 16/3 multiplied by 8/7. So you multiply the fractions together to get 128/21.
