Answer:
Louis needs to save 15+39 = $ 54 dollars
Step-by-step explanation:
\begin{aligned} 15 + 39 &=& \\ 10 + 5 + 30 + 9 &=&\\ 10 + 30 + 5 + 9 &=&\\ 40 + 10 + 4 &=&\\ 54. \end{aligned}
So Louis needs to save \$54.
There were 20 football players in the room. Because the ratio of football players to soccer players was 5 to 7, that meant that, should the ratio represent the actual number of football players in the room, there would be 12 football players in the room. However, the ratio has to be set equal to accomodate the 48 football players, therfore the 12 hypothetical players in the room would have to be multiplied by 4 to equalize. But that also means that everything else in the ratio will have to be multiplied by 4 to truly balance the ratio. Since there were 5 out of 12 football players, and there are actually 48 football players, and 12 times 4 equals 48, then 5 times 4 should give us our actual number of football players. Finally, some basic math will tell you that because 5 times 4 equals 20, and we can say that there are actually 20 football players in the room.
First you have to get the variable to one side.
To do this you have to subtract 2/3x from both sides.
4/3x-2/3x=2/3x
Now you have:
1/6=2/3x
Divide by 2/3
1/6÷2/3=1/6×3/2=3/12=1/4
Your answer is:
X=1/4
Answer:
The density of oak is <u>0.695</u> grams per cubic centimeter.
Step-by-step explanation:
Given:
Oakwood has a mass of 2.85 kilograms and a volume of 4100 cubic centimeters.
Now, to find the density of oak in grams per cubic centimeter.
Mass (m) = 2.85 kilograms.
So, using conversion factor we convert into grams:

Volume (v) = 4100 cubic centimeters.
Now, to get the density by using formula:



Therefore, the density of oak is 0.695 in grams per cubic centimeter.
