<span>4|2x − 2| + 10 = 34
</span><span>4|2x − 2| + 10 - 10 = 34 - 10
</span><span>4|2x − 2| = 24
</span><span>|2x − 2| = 24/4 = 6
2x - 2 = 6 or 2x - 2 = -6
2x = 6 + 2 or 2x = -6 + 2
2x = 8 or 2x = -4
x = 8/2 or x = -4/2
x = 4 or x = -2
To check for extraneous solutions:
</span>For x = 4: <span>
4|2(4) − 2| + 10 = 34
4</span><span>|8 − 2| = 34 - 10 = 24
6 = 24/4 = 6 (solution is valid)
</span><span>For x = -2: <span>
4|2(-2) − 2| + 10 = 34
4</span><span>|-4 − 2| = 34 - 10 = 24

Therefore, solutions are x = 4 , x = -2

Step-by-step explanation:
Answer: there are a total of 7 marbles
Step-by-step explanation:
The chance of the first marble being blue is 4/7. Now we only have 6 marbles in the bag (3 red and 3 blue)

Answer:
2n-2
Step-by-step explanation:
h(n+1) = 2(n+1)-4
=2n+2-4
=2n-2
15 miles is five times 3 miles.
It will take 40*5=200 minutes to go 15 miles.
200 minutes = 3+20/60 hours = 3hrs 20min
