Answer: the weight of each bags are 1.85kg,
1.85kg and 3.05 kg
Step-by-step explanation:
Total weight of the three bags is
6 3/4 kg. Converting to decimal, it becomes 6.75
kg.
Two of them have the same weight. Let X
represent the bags of equal weight. Their total
weight would be 2x. The third bag is heavier
than each of the bags of equal weight by 1 1/5
kg. Converting to decimal, it becomes 1.2kg. It
means that the weight of the third bag would be
x + 1.2
Therefore, for the three bags,
2x + × + 1.2 = 6.75
3x = 6.75 - 1.2 = 5.55
x=5.55/3=1.85
Weight of the third bag is
1.85+1.2=3.05kg
Answer:
Question 1: x + 8 + 3x + 8 = 48
Question 2: Alicia is 8, her aunt is 24
Step-by-step explanation:
Question 1: 'x' represents Alicia's age. 3x is her aunt's age because her aunt is 3 times her age. In 8 years, their combined age will be 48. They each age 8 years, so x becomes x + 8, and 3x becomes 3x + 8
Question 2: solve the equation x + 8 + 3x + 8 = 48
4x + 16 = 48 (combine like terms)
4x = 32 (subtract 16 from both sides)
x = 8 (divide by 4 on both sides)
Since x is Alicia's age, she is 8, since 3x is her aunt's age, her aunt is 3(8) = 24
Length / wingspan
14.8 / 9.8 = 0.5 / x
cross multiply
(14.8)(x) = (9.8)(0.5)
14.8x = 4.9
x = 4.9 / 14.8
x = 0.331 meters....wingspan of model
