Answer: 14 days
Step-by-step explanation:
Day 1: 1 minute snooze = 24 minutes
Day 2: 2 minute nooze = 23 minutes ; these examples show snooze time = days.
We can set up an equation for this situation: 25 - s = r ; where s = snooze time and r = time to get ready.
Given the problem, we can fill out this equation with: 25 - s = 11
When you solve this equation, time snoozed = 14.
We already know that snooze time = days, so days = 14.

Answer: x= -189, y =252
Step-by-step explanation:
Let the first number be x and second number be y
so
x + y = 63
x = 63-y
now
1/9 of x + 1/6 of y = 21
x/9 + y/6 = 21
substituting x's value from equation i
(63-y)/9 + y/6 = 21
(378-6y+9y)/54 = 21
378+3y = 1134
3y = 1134-378
so, 3y = 756
so, y = 756/3
so, y = 252
now
x = 63-252
so, x = -189

Answer:the mean is 90
Step-by-step
you find the sum of the values then divide them by the amount of numbers in the set
D
The first place after the decimal represents the tenths place, the second place represents the 100ths place and so on.
