1. 2.50x + 5 = C
2.50(4.1) + 5 = C
$15.25
2. 15.25(1.15)
$17.54
3 B, I believe but dont quote me.
4. 206 / 60 + 30
236 minutes
Answer:
The mean is the average of a set of data.
Example:
To find the mean, add up all of the numbers in the set and divide by the number of values that you added.
35 + 36 + 37 + 38 + 40 + 40 + 41 + 42 + 43 + 55 + 55 + 55 + 56 + 57 + 58 + 59 = 747
Then, divide by the number of values, which is 16.
747/16=46.68
Answer:
2(x+9)
Step-by-step explanation:
2x+18
find the common number which can fit into 2x and 18

Answer:
12
Step-by-step explanation:
12 = 2 digits
1 + 2 = 3
1 < 2
A = 1/2 BH
#17
B = 3 H = 4
A = 1/2 BH
A = 1/2 (3)(4) = 6
#18
B = 6 H = 4
A = 1/2 BH
A = 1/2 (6)(4) = 12
#19
B = 12 H = 8
A = 1/2 BH
A = 1/2 (12)(8) = 48
#20
B = 11 H = 5
A = 1/2 BH
A = 1/2 (11)(5) = 27.5
