Answer:
29 degrees
Step-by-step explanation:
9: 2x - 2 + x + 5 = 90
3x + 3 = 90
3x = 90 - 3
3x = 87
x = 29 degrees
Answer: c = 1.05p
Step-by-step explanation:
Price of the hat = p
Percentage increase in the price of the hat = 5%
The equation to calculate the increase of the total cost, c, of the hat will be:
c = p + (5% × p)
= p + (5/100 × p)
= p + (0.05 × p)
= p + 0.05p
c = 1.05p
Answer:
30
Step-by-step explanation:

Answer:
no mode
The median and mode are 12
Step-by-step explanation:
The mode is the number that appears most often
Since no number repeats there is no mode
The mean is the average
Add up all the numbers
(12+12+12+12+13+13+15)/7 = 89/7 = 12 5/7
The median is the middle number
There are 7 numbers
7/2 = 3.5
The 4th number is the median
The 4th number is 12
The mode is the number that appears most often which is 12
