Answer:
its 6 because the lines show they are parellel so it has to be equal to 18 and 12 plus 6 is 18
Step-by-step explanation:
Answer:
This is not an equation because both sides are not equal.
Step-by-step explanation:
2x+1=2x-1
+1 +1
2x+2=2x
-2x -2x
2=0
5xy+x-8+13x+2=
Combine like terms
5xy+14x-6
Answer:
x=3y-2 substitute is easier to solve the equation
Step-by-step explanation:
given x=3y-2.............(1)
x+3y=4................(2)
put x=3y-2 in equation (2)
3y-2+3y=4
6y-2=4
+2
6y=6
y=1
x=3y-2
x=3(1)-2=1
x=3y-2 substitute is easier to solve the equation answer
Answer:
Step-by-step explanation:
Remark
I hope you have some idea how to make your calculator use logs. This problem is impossible without being able to take the log of each side.
Solution
log(8)^x > log 24 Logs lets you bring down x and multiply it by log24
x log 8 > log 24 Be careful what you do next. Don't use log 3
x > log(24)/log(8)
x > 1.3802/0.9031
x>1.5284
As wrong as this may look, it is correct.
Check it
8^1.5284 = 24.00395
The difference is that 1.5284 has been rounded just a slight bit.
