Answer:
X=7
Step-by-step explanation:
STEP 1: Simplify both sides of the equation
7x + -10 + 2x =39 + 2x
(7x + 2x) + (-10) = 2x + 39 (combine like terms)
9x -10 = 2x + 39
step 2: Subtract 2x from both sides
9x -10 - 2x = 2x + 39 - 2x
7x - 10 =39
Step 3: Add 10 to both sides.
7x - 10 + 10 = 39 + 10
7x = 49
Step 4: Divide both sides by 7.
7x/ 7 = 49/7 <u> x=7</u>

Answer:
BD = 6
Step-by-step explanation:
Theorem: The altitude to the hypotenuse of a right triangle is the mean proportional between the segments of the hypotenuse.
So, 

BD = 6
See how easy that is IF you know the theorem.
When will they blink together?
what is the smallest number they both mutiply to
3*5=15
so every 15 seconds
so at 15, 30, 45, 60 seconds
so 4 times if you count the time exactly at 1 minute
