Step-by-step explanation:
the perfect squares =
81, 121, 625
For blank 1:
$14 for 4 pounds. so 84/14= 6, then 6x4= 24. 24 pounds of apples
For blank 2:
If an apple is approx 5 ounces, 16/5 isn't a whole number, but 15/5 is, so 3, There are about 3 apples in each pound
For blank 3:
3 apples in each pound, and you can buy 24 pounds, 3x24=72
Answer:
Pizza = 12.35
Chips = 2.75
Step-by-step explanation:
Let :
Pizza = x
chips = y
3x + 4y = 48.05 - - - (1)
5x + 2y = 67.25 - - - (2)
Multiply (1) by 5 and (2) by 3
15x + 20y = 240.25
15x + 6y = 201.75
Subtract :
20y - 6y = 240.25 - 201.75
14y = 38.50
y = 38.50/ 14
y = 2.75
Put y = 2.75 in (1)
3x + 4(2.75) = 48.05
3x + 11 = 48.05
3x = 48.05 - 11
3x = 37.05
x = 37.05 / 3
x = 12.35
Pizza = 12.35
Chips = 2.75
