Convert 53 yards per hour into inches per day

marin [14]

1 yard = 36 inches.

53 yards per hour x 36 inches per yard = 1908 inches per hour.

1 day = 24 hours.

1908 inches per hour x 24 hours = 45,792 inches per day.

If f ( x ) = 3x² - 5x + 7 , Show that f ( -1 ) = 3 f ( 1 ) .<br><br><br><br><br>Tysm :')

Lelechka [254]

Solution :

3x² - 5x + 7

put x = -1

3(-1)² - 5(-1) + 7

3(1) + 5 + 7

3 + 12

Now, put x = 1

3(1)² - 5(1) + 7

3(1) - 5 + 7

3 + 2

here :

f(-1) = 15

f(-1) = 3(5)

f(-1) = 3 f(1)

Round your answer to the nearest hundredth.<br><br> 13.48x − 200 < 256.12

wolverine [178]

Answer:

Step-by-step explanation:

13.48x − 200 < 256.12

Using the addition property , add 200 to both sides

That's

13.48x + 200 - 200 < 256.12 + 200

13.48x < 456.12

<u>Divide both sides by 13.48</u>

$\frac{13.48x}{13.48} < \frac{456.12}{13.48} \\ x < \frac{456.12}{13.48} \\ \: \: \: x < 33.83679$

We have the final answer as

x < 33.84 to the nearest hundredth

Hope this helps you
