Wanda started walking along a path 2 minutes (120 seconds) before Dave. Wanda walked at a constant rate of 5 feet per second. Da
igor_vitrenko [27]
First we write the kinematics equations:
 a
 v = a * t + vo
 r = a * (t ^ 2/2) + vo * t + ro
 For Wanda we have:
 a = 0
 v = 5
 r = 5 * t
 For Dave we have:
 v = 10
 r = 10 * (t-120)
 To solve the system of equations, we graph both functions and see where
they intersect.
 We have to intersect in the ordered pair:
 (t, r) = (240, 1200)
 answer
 If they continue walking at these rates, Dave catch up to Wanda in 240s (1200 ft)

What would not be a step in solving 18=2(4+x)
Neko [114]

Step-by-step explanation

Well you gave no answer choices so here are the steps and maybe you can just find out which one isn't here :)

18=2(4+x) first multiply 2 into 4+x

18=8+2x then subtract 8 from the other side

10=2x divide both sides by 2

x=5

Best of luck <3

Which of the following equations is equivalent to 2x+7 = 27
allochka39001 [22]

Answer: C

Step-by-step explanation: The answer is C because x is equivalent to 10 in both problems. X is equal to 10 in the problem 2x + 7 =27 because 2 x 10 = 20 + 7 = 27. X is also equal to 10 in the problem 5x - 15 = 35 because 5 x 10 = 50 - 15 = 35. This means the answer is C.
