Answer:

r = 72

Step-by-step explanation:

1/6r + 2 = 1/9r + 6

1/6r - 1/9r = 6 - 2

3/18r - 2/18r = 6 - 2

1/18r = 4

r = 4 / 1/18

r = 4 * 18

r = 72

aev [14]

Answer: Distance from Cleveland to Cincinnati on the second map is 8 km.

Step-by-step explanation:

Since we have given that

The scale on the first map is

$1\ cm:10\ km$

That means

$1\ cm=10\ km$

Distance from Cleveland to Clncinnati = 40 cm

So,

$1\ cm=10\ km\\\\40\ cm=10\times 40\ km\\\\40\ cm=400\ km$

Similarly, Scale on the second map is given by

$1\ cm:50\ km\\\\i.e.\\\\1\ cm=50\ km$

So, our 400 km in second map will be

$\frac{400}{50}\ km=8\ km$

Hence, Distance from Cleveland to Cincinnati on the second map is 8 km.

Nikolay [14]

If we let x be his hourly rate, his basic pay is equal to 20x. The equation that would best described the given above is expressed as,
20x + (1500 - 20x)(0.16) = 1500
The value of x from the equation is 75. Therefore, Piper's hourly rate is $75.
