Answer:270 + 520
Step-by-step explanation:
268+524
268 and round up 270
524 and round down 520
The fish box is 6 * 6 * 4 = 144 cubic square inches
144 = one box so divide 3456 by 144 to see how many boxes will go into the aquarium
3456 / 144 = 24
24 boxes of fish food could fit in the aquarium
Answer:
0.84 kg
Step-by-step explanation:
Given that :
Weight per liter = 1.12kg per liter
That is 1 Litre weighs 1.12 kilogram
The weight of saline solution of 0.75 Litre will be :
1 Litre = 1.12 kg
0.75 Litre = x
Cross multiply :
1 * x = 1.12 * 0.75
x = 0.84 kg
Hence, 0.75 Litre weighs 0.84 kg
Answer:
(2x - 5y)²
(2x - 5y)(2x - 5y)
2x(2x - 5y) - 5y(2x - 5y)
2x(2x) - 2x(5y) - 5y(2x) + 5y(5y)
4x² - 10xy - 10xy + 25y²
4x² - 20y + 25y²
The answer is B.
Step-by-step explanation:
J=justin
marcella=m
aimee=a
j is 2 older than 1/3 of m
'of' means multiply
j=2+1/3m
a is 4 younger than 2 times j
a=-4+2j
represent justin's age?
dunno
ok so I can solve if I know m=63
j=2+1/3m
j=2+1/3(63)
j=2+21
j=23
subsitute
a=-4+2j
a=-4+2(23)
a=-4+46
a=42
justin is 23 and aimee is 42 if marcella is 63
