Answer:
answer: b) x = 3, x = -1
Step-by-step explanation:
3|2x - 2| + 6 = 18.
divid by 3 :
|2x - 2| + 2 = 6
add -2 : |2x - 2| = 4
2x-2=4 or 2x-2=-4
2x=6 or 2x=-2
x=3 or x=-1

Answer:
26π, 130π, 780π (inches)
Step-by-step explanation:
We first need to find how long the circumference of the circle is, since that is the part of a wheel that determines how far it will go. The formula to find the circumference is 2πr, where r is the radius. This formula is just something you have to remember, there is no way around it.
Now, applying the formula, we find that the diameter of the circle is 26π inches, which means that the bike will go 26π inches every rotation of the wheel.
To find the distance for 5 rotations, we multiply 26π by 5, getting 130π
Similarly, with 30 rotations, we get 26π*30=780π
If you would like to solve the above problem, you can do this using the following steps:
1.2 miles * 7 days = 1.2 * 7 = 8.4 miles ... Multiply 1.2 by 7.
2.4 miles * 7 days = 2.4 * 7 = 16.8 miles ... Multiply 2.4 by 7.
8.4 miles + 16.8 miles = 25.2 miles ... Add the two products.
The correct result would be A.
