Answer:

Correct choice is 4.

Step-by-step explanation:

Tyrone determines it takes him 58.2 minutes to travel 30 miles to work, then he travels with speed

\dfrac{30}{58.2}=\dfrac{300}{582}=\dfrac{50}{97}\ \text{miles per minute}.

If 1 mile = 5,280 feet, then his speed is

\dfrac{50}{97}\cdot 5280=\dfrac{264000}{97}\ \text{feet per minute}.

Since 1 minute = 60 seconds, then his speed is

\dfrac{264000}{97\cdot 60}=\dfrac{4400}{97}\approx 45.36\ \text{feet per second}.

Helpppppppppp please
eduard

You know b=-6 and since you know this, you can plug -6 in for b.

This would become 4(-6) + 6 divided by 6.

You can then multiply 4 and -6 together,

-24 + 6 / 6

You can then add -24 and 6 together,

-18/6

You can then divide -18 by 6,

-18/6=-3

-3 is your final answer
