-20x+18≥-102 solve this inequality
larisa [96]

Answer:

1) x≥6

--------------------------------------

--------------------------------------

2) h  > 20

Mark worked more than 20 hours.

Step-by-step explanation:

1) -20x+18≥-102

-20x≥-102-18

-20x≥-120

Dividing -20 both side

\frac{-20}{-20}x≥\frac{-120}{-20}

x≥6

--------------------------------------

--------------------------------------

2) 14h + 25 > 305

14h  > 305-25

14h  > 280

Dividing 14 both side

\frac{14}{14}h > \frac{280}{14}

h  > 20

Mark worked more than 20 hours.

If q varies inversely as r, and q = 10 when r = 2.5, find the equation that connects q and r. question 2 options: q=r25 q=r4 q=2
KengaRu [80]

The variation equation is qr = 25

<h3>How to determine the equation?</h3>

An inverse variation is represented as:

qr = k

Where k is the constant of variation

When q = 10 and r =2.5, we have:

k = 10 * 2.5

Evaluate

k = 25

Substitute k = 25 in qr = k

qr = 25

Hence, the equation is qr = 25
