Answer: x = 10
Step-by-step explanation:
Since B is the midpoint, segment AB and segment BC are equal to each other
3x - 8 = x + 12
Subtract x on both sides.
2x - 8 = 12
Add 8 to both sides
2x = 20
Divide by 2 on both sides
x = 10
Answer:
Step-by-step explanation:
Alright, lets get started.
The given equation is :
If we divide the equation with -2 in both sides
Subtract 3 in both sides
So, the first step of simplifying equation is divide equation with -2. : Answer
Hope it will help :)
Answer:
170 miles apart
Step-by-step explanation:
1 inch is 17 miles, so 10 inches will represent 170 miles.
x stands for inches, y for miles, and * for multiplication.
First we multiply both sides by 10, then we simplify.
Answer:
y=t−1+ce
−t
where t=tanx.
