Answer:
x + 2y
Step-by-step explanation:
so 3x + 2y - 3x, group the like terms 3x - 3x = x
So x + 2y, i think i did that right
hi how you doing
BTW why do we have to click answer question to get to chat box
um hello?
how do you answer the thing
1. Answer: 15.7143
log (7x-10)=2
Use the identity: loga(x)=b = x=(a)(b)
7x-10=10^2
Evaluate the Power
7x-10=100
Addition Property of Equality
7x=110
Division Property of Equality
x=110/7 or 15.7143
2. Answer: 0.3107
log(3)+log(x^-3)=2
log(3x^-3)=2
log(3 x 1/x^3)=2
log(3/x^3)=2
3/x^3=10^2
3/x^3=100
3=100x^3
3/100=x^3
Answer Cube root 30 / 10 or 0.3107
3. Answer: 0.002
log(5) + log(x) = -2
log(5x)= -2
5x= 10^-2
5x=1/10^2
5x=1/100
x=1/500
Answer: 0.002
Honestly I could tell you the steps, but I do not have a lot of time. Sorry. I will comment later if you need the steps
There is a baseball game. It is 2$ for every person, which is x, that wants to watch the game. After the game, you pay the umpires a total of 125$. After the end of the day you have made 400 dollars. How many people came to the game. So find x.
