Answer:
Step-by-step explanation:
v=d/t, t=d/v, since t=t
1225/(v+w)=1100/(v-w)
1225v-1225w=1100v+1100w
2325w=125v
w=125v/2325, given v=575
w=125(575)/2325
w=30.91 mph
Answer:
See below.
Step-by-step explanation:
(a) A sequence is an ordered list of numbers whereas a series is the sum of a list of numbers.
(b) A series is convergent if the sequence of partial sums is a convergent sequence (that is tends to a limit). A series is divergent if it is not convergent.
<span>x+y=4 and x= -1
-1 + y = 4
y = 5

The two equations are vertical angles, which mean they are equal.
Set each equation to equal each other and solve for x.
3x-3 = 6(x-10)
Simplify the right side:
3x-3 = 6x-60
Subtract 3x from each side:
-3 = 3x - 60
Add 60 to each side:
57 = 3x
Divide both sides by 3:
x = 57 / 3
x = 19
