to begin with, we have to add 12x+9y+-2y we add like terms(y and y)
12x+7y
next, we have to subtract 4x-3y from 12x+9y
(12x+9y)-(4x-3y)
our answer is: 8x+12y
Answer:
0.0245
Step-by-step explanation:

Answer:
D
Step-by-step explanation:
Take 1200+1300+850= 3350
Money per week

8*10*5= 400 $ per week
3350/400= 8.3
Answer:
Mean = 44.
Mean is the average.
Add all numbers:
(43 × 3) + (44 × 5) + (45 × 2) + 46
(129) + (220) + (90) + 46
= 485
Divide by number of points:
485 ÷ 11 = 44.090909 (09 repeating)
Round to 44.
Median = 44
Median is the middle-most number.
Line all the values up:
43, 43, 43, 44, 44, 44, 44, 44, 45, 45, 46
'Cross' numbers off from each side until you reach the middle- 44.
Mode = 44
Mode is the number that appears most often. 43 appears three times, 44 appears five, 45 appears twice, and 46 appears once. Five was the greatest reoccurrence. Therefore, 44 is the mode.
Range = 3
Range is the distance between the smallest value and the largest value.
Smallest number: 43
Largest number: 46
46 - 43 = 3
