Answer:

B. $\frac{60 hours}{1} \times \frac{1 day}{24 hours}$

Step-by-step explanation:

Converting 60 hours to days:

24 hours = 1 day

60 hours = x day

Cross multiply

$24 hours \times x = 60 hours \times 1 day$

Divide both sides by 24 hours

$x = \frac{60 hours \times 1 day}{24 hours}$

Thus,

$\frac{60 hours \times 1 day}{24 hours} = \frac{60 hours}{1} \times \frac{1 day}{24 hours}$

The expression that shows how to convert 60 hours to days is:

$\frac{60 hours}{1} \times \frac{1 day}{24 hours}$

Which number line shows the solution to the inequality -2(3x-1)<8

Zigmanuir [339]

Answer:

$x > -1$

Step-by-step explanation:

Given

$-2(3x - 1) < 8$

Required

Show on a number line

$-2(3x - 1) < 8$

Divide through by -2

$\frac{-2(3x - 1)}{-2} < \frac{8}{-2}$

$3x - 1 > -4$

Add 1 to both sides

$3x -1 + 1 > -4 + 1$

$3x > -3$

Divide through by 3

$x > -1$
