Answer: 75%
Step-by-step explanation:
35% of 5 liters is 1.75 liters
1.75 liters + 8 liters = 9.75 liters (only juice)
(5 liters + 8 liters = 13 liters) (the whole thing)
So, 9.75/13 is 75%
Answer:
3
Step-by-step explanation:
-(x-4)+5=3x+6-x(BODMAS)
-x+4+5=3x+6-x(collect like terms )
4+5=3x+x-x
9=3x (divide both sides by 3)
9/3=3x/3
3=x
Answer:
True.
Step-by-step explanation:
We can represent an odd number by 2n + 1 where n = 0, 1, 2, 3, 5 etc.
Substituting:
a^2 + a = (2n + 1)^2 + 2n + 1
= 4n^2 + 4n + 1 + 2n + 1
= 4n^2 + 6n + 2
= 2(2n^2 + 3n + 1)
which is even because any integer multiplied by an even number is even.
This is also true if we use a negative odd integer:
We have 4n^2 + 4n + 1 - 1 - 2n
= 4n^2 + 2n
= 2(2n^2 + n(.
<span> If Jim has x football cards</span>
<span>He will have 5x baseballs cards</span>
Thus
<span> x + 5x = 120 >
total # of cards</span>
<span> 6x = 120</span>
<span> x= 120/6 =
20</span>
<span> so Jim has 5x
baseball cards = 20*5 =100 baseball cards</span>
