Coins Tossed three times.
Sample = [HHH] [HHT] [HTT] [TTT] [TTH] [THH] [HTH] [THT]

Events with 1 Head and Two Tails = [HTT] [TTH] [THT] = 3

P = 3/8

What is x+y=10;y=x+10

Alenkasestr [34]

[ Answer ]

$\boxed{\bold{X \ = \ 0, \ Y \ = \ 10}}$

[ Explanation ]

System Of Equations $\bold{\left \{ {X \ + \ Y \ = \ 10} \atop {Y \ + \ X \ = \ 10}} \right.}$

-----------------------------------

[Substitute] Y = X + 10

$\bold{\begin{bmatrix}x+x+10=10\end{bmatrix}}$

Isolate x for x + x + 10 = 10: x = 0

For y = 10

Substitute x = 0

Y = 0 + 10

0 + 10 = 10

y = 10

Solutions

X = 0

Y = 10

$\boxed{\bold{[] \ Eclipsed \ []}}$

A rowing team rowing with the current traveled 36 km in 3 h. Rowing against the current, the team rowed 12 km in the same amount

alex41 [277]

Answer:

team: 8 kph
current: 4 kph

Step-by-step explanation:

The downstream speed is ...

speed = distance / time

speed = 36 km/(3 h) = 12 km/h

The upstream speed is ...

12 km/(3 h) = 4 km/h

If b and c represent the speeds of the boat and current, respectively, then we have ...

b + c = 12

b - c = 4

Adding these gives ...

2b = 16

b = 8

c = b -4 = 4

The rate of the rowing team in calm water is 8 km/h; the rate of the current is 4 km/h.
