The ideal width of a safety belt strap for a certain automobile is 7 cm. An actual width can vary by at most 0.3 cm. Write an absolute value inequality for the range of acceptable widths.


A.|w – 0.3| ≤ 7

B.|w + 7| ≤ 0.3

C.|w – 7| ≤ 0.3

Respuesta :


[tex](7-.3) \leq w \leq (7+.3) [/tex]

[tex]6.7 \leq w \leq 7.3[/tex]

[tex]w - 7 = -0.3[/tex]

[tex]w = 6.7 [/tex]

So the answer is

C. |w – 7| ≤ 0.3

Answer:
