Step-by-step explanation:
Assume that all 93 cartons were 600mL.
Volume of milk = 93 * 0.6L = 55.8L
Difference between Actual and Total
= 79.8L - 55.8L = 24.0L
For every 600mL carton that becomes 1L,
the volume of milk will increase by 0.4L.
=> 24.0L / 0.4L = 60
Hence there were 60 1L cartons and 93 - 60 = 33 600mL cartons of milk.
Answer:
5.)
r - 14 = 10
r = 10 + 14
r = 24
6.)
x - 8 = 64
x = 64 + 8
x = 72
7.)
3² + 1( 3³ ÷ 3)
9 + 1( 9 ÷ 3)
9 + 1(3)
9 + 3 = 12
8.)

Answer:
(x+2)(2x+1)
Step-by-step explanation:
x times 2x is 2x^2
x times 1 is x
2 times 2x is 4x
2 times 1 is 2
Overall
2x^2+x+4x+2
add x and 4x:
2x^2 + 5x + 2
So (x+2)(2x+1) is the answer
