Answer:
24
Step-by-step explanation:
A is 4 times that of B ie
A = 4B (1)
A is also 3 times that of C ie
A = 3C (2)
From equation 1,
B = A/4
From equation 2,
C = A/3
But the there are 38 sweets in the 3 boxes i.e
A + B + C = 38
A + A/4 + A/3 = 38
Multiply through by 12 to express in linear form
12A + 3A + 4A = 456
19A = 456
Dive both side by 19
A = 456/19
A = 24
Answer:
x = 42
Step-by-step explanation:
a striaght line = 180°
z + y + x = 180
103 + 135 + x = 180
138 + x = 180
subtract 138 from both sides
138 - 138 + x = 180 - 138
x = 42
Answer:
6.08 kg bag unit price: $1.72
7.48 kg bag unit price: $1.86
6.08 kg bag is the better buy
Step-by-step explanation:
To find unit price, divide the price by the amount. 10.47 divided 6.08 equals 1.7203947. Round it to the nearest cent to get 1.72. So, the unit price for the first bag is $1.72. Next divide 13.88/7.48 to get 1.85561. Round it to the nearest cent to get 1.86. So, the unit price for the second bag is $1.86 per kg. The better buy is the cheaper one, so the 6.08 kg bag is a better deal. Hope this helped!
