Answer:
1.40
Step-by-step explanation:
Two parallel lines are intersect by the same line, and the angles shown lie on the same orientation about the intersection so the angles are equal to each other...which means:
9x+21=10x+10 subtract 21 from both sides
9x=10x-11 subtract 10x from both sides
-x=-11 divide both sides by -1
x=11
Answer:
x=5
Step-by-step explanation:
First, let's understand logarithms.
When there is no base given, like in this problem's right side of the equation, the base is automatically 10.
So, let's re-write that.

Now, let's test a few of the numbers out. For brevity, I already know it's 3. Let's show you why.
