A. 13
Explanation= 6 (sons) +6 (daughters) +1 (mother) = 13.
(notes: as a father is not within the problem, there is no reason to be in the answer)
Quantity equation: t + s = 48kg
Copper equation: 23t + 79s = 44*48
Multiply the quantity equation by 23 to set the problem up for the elimination method.
23t + 23s = 23*48
23t + 79s = 44*48
Subtract to solve for s.
56s = 21*48
s = 18 [Number of 79% bars needed]
t = 48 - 18 = 30 [Number of 23% bars needed]
Answer:
1) 5/6 + 2/5 = 37/30 2) 1/6 - 1/10 = 1/15
Step-by-step explanation:
1) 5/6 + 2/5
25+12/30
= 37/30
2) 1/6 - 1/10
5-3/30
2/30
simplify the fraction
= 1/15
