0 because 10 - 10 equals 0
Answer:
ok so if it is 0.7 to buy fruit and 0.6 to buy a cd so we turn these into fraction and multiply
7/10*6/10=42%
Hope This Helps!!!

<h3><u>Question</u></h3>
The amount of money that Charlie saves each week is directly proportional to the amount he earns. Last week Charlie saved $32 on his earnings of $512. At the same rate, how much will Charlie save this week on his earnings of $448?
<h3><u>Answer:</u></h3>
Charlie saved $ 28
<h3><u>Solution:</u></h3>
Given that amount of money that Charlie saves each week is directly proportional to the amount he earns
Let y represent of saved money and x represent amount of earned money
Therefore,
![\text{ Amount of money saved each week } $\propto$ amount he earns](https://tex.z-dn.net/?f=%5Ctext%7B%20Amount%20of%20money%20saved%20each%20week%20%7D%20%24%5Cpropto%24%20amount%20he%20earns)
![y \propto x](https://tex.z-dn.net/?f=y%20%5Cpropto%20x)
y = kx --- eqn 1
Where "k" is the constant of proportionality
<em><u>Last week Charlie saved $32 on his earnings of $512</u></em>
y = 32 and x = 512
Substituting in eqn 1, we get
![32 = k(512)\\\\k = \frac{32}{512} = 0.0625](https://tex.z-dn.net/?f=32%20%3D%20k%28512%29%5C%5C%5C%5Ck%20%3D%20%5Cfrac%7B32%7D%7B512%7D%20%3D%200.0625)
To find amount of saved money, we will substitute k = 0.0625 and x = 448 in eqn 1
y = 0.0625(448) = 28
Thus charlie saved $ 28
Answer:
i think the answer is 8
Step-by-step explanation:
"three less than the quotient of 6 and a number (n=3) increased by nine"
(6÷3)-3+9
the quotient of 6 and 3 (6÷3) is 2
three less than 2: 2-3 which equals -1
increased by nine: -1+9 (which is also the same as 9-1) is 8
please don't hesitate to ask for clarification! hope i helped!
