Answer:

x=1 x = -1

Step-by-step explanation:

2|5x|= 10

Divide each side by 2

2/2|5x|= 10/2

|5x|= 5

Absolute values have 2 solutions, one positive and one negative

5x = 5 5x = -5

Divide each side by 5

5x/5 = 5/5 5x/5 = -5/5

x = 1 x = -1

Answer:

Step-by-step explanation:

● 2|5x| = 10

● 2 × |5| ×x = 10

5 is positive so |5| = 5

● 2×5× |x| = 10

● 10×|x| = 10

● |x| = 10

● x = 1 or x = -1

A wheel has a diameter of 21 inches. Approximately how far does it travel in 3 revolutions? A. 63 in. B. 65.94 in. C. 98.91 in.

Paul [167]

If a wheel makes a full turn, it will have traveled the entire distance around that wheel. After 3 revolutions, it should have traveled 3 times its circumfrence.
The circumfrence of a circle is equal to the diameter times pi. (about 3.14)
21 × 3.14 = 65.94 = circumfrence = 1 revolution
3 revolutions = = 65.94 × 3 = D. 197.82 in.
