Answer:

The answer would be a=2.

Step-by-step explanation:

Since both sides of the equation are being multiplied by b then you would divide both of them by B. This will just remove the B from the equation entirely and leave you with a=2. I hope that this was helpful.

andrew11 [14]

Answer:

Amount \ left = 1345.81

Step-by-step explanation:

Total  \  earning = T= $3,511.95

Spent \ on \ Shopping = S = 2($21.99) + $14.99\\S = 58.97

Amount \ left = L = R - S\\Amount \ left = 1404.78 - 58.97\\Amount \ left = 1345.81

Answer:

(\frac{-9}{2},\frac{11}{2})

Step-by-step explanation:

you have to use the midpoint formula which is

(\frac{x1+x2}{2},\frac{y1+y2}{2})

so you plug your numbers in

(\frac{-12+3}{2},\frac{-3+-8}{2})

Add the tops

(\frac{-9}{2} ,\frac{-11}{2} )

if possible simplify

and that is your answer

ILL MARK BRAINLY!!
Finger [1]

Answer:

D

Step-by-step explanation:

When you put something in parenthesis by a number, your multiplying each individual number by the number outside of parenthesis. Therefore, 5(2) = 10 and 5(7) = 35 and that equals 45, and 5(2+7) you distribute the 5 to both numbers and get 10+35 which equals 45 aswell.

A bus went halfway from a village to a city at a certain speed. Then it stopped in traffic for an hour. In order to catch up the
k0ka [10]
We have to assume that the speed before being stuck was sufficient to get to the destination on time had there been no delay. Call that speed "s" in km/h.

Since 200 km is "halfway", the total distance must be 400 km.

time = distance / speed
total time = (time for first half) + (delay) + (time for second half)

400/s = 200/s + 1 + 200/(s+10) . . . .times are in hours, distances in km
200/s = 1 + 200/(s+10) . . . . . . . . . . subtract 200/s
200(s+10) = s(s+10) +200s . . . . . . .multiply by s(s+10)
0 = s² +10s - 2000 . . . . . . . . . . . . . .subtract the left side
(s+50)(s-40) = 0
Solutions are s = -50, s = 40

The speed of the bus before the traffic holdup was 40 km/h.
