Step-by-step explanation:
Your original inequality is
.. w -2 ≤ 8
The additive property of equality applies to inequalities as well as to equations. You use the additive property of equality to solve this. Add 2 to both sides.
.. w -2 +2 ≤ 8 +2
The purpose of adding 2 is to cancel the effect of subtracting 2. That is, -2+2=0, and w+0 = w.
.. w ≤ 10
The correct selection would be B.
Answer:
The answer is the last line.
Step-by-step explanation:
Use the quadratic formula
a = 1
b = -a
c = a^2 - b
x = -b +/- sqrt(b^2 - 4ac)
=================
2a
x = a +/- sqrt(a^2 - 4(1)*(a^2 - b)
========================
2
x = a +/- sqrt(a^2 - 4a^ + 4b)
=====================
2
x = a +/- sqrt(4b - 3a^2)
===================

The first car is traveling at 65 miles per hour and the second car is traveling at 62 miles per hour.
Explanation:
390:x=372:(x-3)
372x=390(x-3)
372x=390x-1170
1170=390x-372x
1170/18=18x/18
x=65
x-3= 65-3=62
