Answer:

t = 7

Step-by-step explanation:

5(2t - 3) – 7.5t = 0.5(12 – t)

5*2t - 3*5 - 7.5t = 12*0.5 - t *0.5

10t - 15 - 7.5t = 6 - 0.5t {Now, combine like terms}

10t - 7.5t - 15 = 6 - 0.5t

2.5t -15 = 6 - 0.5t {Add 15 to both sides}

2.5t = 6 - 0.5t + 15

2.5t = 21 - 0.5t { Add 0.5t to both sides}

2.5t + 0.5t = 21

3t = 21 {Divide both sides by 3}

t = 21/3

t = 7

You bike for 2 hours at a speed no faster than 17.6 mph. Write an inequality that represents the possible number of miles you bi

Whitepunk [10]

Total no. of hours you spent biking = 2 hours
the speed at which you rode your bike ≤ 17.6 mph
Now,
We have,
$speed = \frac{distance}{time}$

$17.6 = \frac{distance}{2}$

$17.6 *2= distance$

$35.2=distance$

So, you for given conditions, you can't travel more then 35.3 miles

So, the inequality for the given circumstances is:
x ≤ 35.2
