Answer:
47.5%
Step-by-step explanation:
39/82 = .475 = 47.5%
Since y=-3 you need to set up the equation
-20-(-3)
And all you have to do is simplify
So your answer will be
-17
Hope this helped :)
Have a great day
<span>Ivan DATA:
rate = 12 mph ; time = t hrs ; distance = 12t miles
</span><span>Kate DATA:
rate = 16 mph ; time = t-(3/2) hrs ; distance = 16t - 24 miles
</span><span>Equation:
12t + 16t-24 = 40 miles
</span><span>28t = 64
time = 16/7 = 2hr 17 min
Ans: 8:00 + 2hr 17 min = 10:17AM</span>
<span>We simplify the equation to the form, which is simple to understand
<span>4x+8-2x=20
We move all terms containing x to the left and all other terms to the right.
<span>+4x-2x=+20-8
We simplify left and right side of the equation.
<span>+2x=+12
We divide both sides of the equation by 2 to get x.
<span>x=6</span></span></span></span></span>
