Jeremiah got $65 on birthday and spent some money on 3 video games and was left with $14.
He purchased 3 video games.
Let the cost one one video game be v.
The cost of each video game is same
So the cost of 3 video games is 3v.
Also he is left with $14 after paying for three games.
Hence
3v + 14 = 65
Subtracting 14 from both sides
3v + 14 -14 = 65-14
3v = 51
Dividing by 3 on both sides
v = 51/3
v = 17
Hence the cost of each video game is $17
Elsa's answer is incorrect since there is a solution of the given equation. In the given logarithmic problem, we need to simplify the problem by transposing log2(3x+5) in the opposite side. The equation will now be log2x-log2(3x+5)=4. Using properties of logarithm, we further simplify the problem into a new form log (2x/6x+10)=4. Then transform the equation into base form 10^4=(2x/6x+10) and proceed in solving for x value which is equal to 1.667.
Answer:
![4x+5=8](https://tex.z-dn.net/?f=4x%2B5%3D8)
![x=\frac{3}{4}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B3%7D%7B4%7D)
Step-by-step explanation:
Let
x ---> the number
we know that
The algebraic expression is equal to multiply the number by 4, add 5 and equal 8
so
![4x+5=8](https://tex.z-dn.net/?f=4x%2B5%3D8)
Solve for x
subtract 5 both sides
![4x=8-5\\4x=3](https://tex.z-dn.net/?f=4x%3D8-5%5C%5C4x%3D3)
Divide by 4 both sides
![x=\frac{3}{4}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B3%7D%7B4%7D)
