Answer:
55.6
Step-by-step explanation:
The mean is found by adding all the numbers together, and dividing by the amount of numbers there are. Note you must round to the tenths place.
(50 + 52 + 52 + 55 + 56 + 56 + 56 + 58 + 58 + 59 + 60)/11
First, combine and add all terms within the parenthesis, and then divide:
(612)/11 = 55.63... , or 55.6 (rounded to the nearest tenth place).
55.6 is your answer.

Convert 1 and 1/2 to eights to make it easier to subtract. 1 4/8 add 1 to 4/8
12/8 then subtract that by 7/8 straight across the numerator. That then equals 5/8
Answer:
a = 0.4 and b=1.6
Step-by-step explanation:
Both expressions are simply divided
(2x + 8y = 60) ÷ (ax + by = 12)
60÷12 = 5, Hence coefficient of x and y in the bigger equation is divided by 5 to find a and b
2/5 = 0.4 = a
8/5= 1.6 = b
