Answer:
50
Step-by-step explanation:
H = Heads, T = tails
1st Coin 2nd Coin Final Outcome, ÷ 4 possible outcomes
H (H,H) 1/4, or 25%
H
T (H,T) 1/4, or 25%
H (T,H) 1/4, or 25%
T
T (T,T) 1/4, or 25%
If order does not matter:
T,T: 25%
TH or HT: 50%
HH: 25%
Answer:
(22, - 24)
Step-by-step explanation:
Multiply the first equation by -5 to make the y's so you can add the up to zero.
-5(2x + y = 20)
-10x - 5y = -100 Add the second equation thn solve for x
<u> 6x + 5y = 12 </u>
-4x = -88
x = 22
Plug 22 in for x in either equation
2x + y = 20
2 (22) + y = 20
44 + y = 20
y = -24
It’s blank is the answer lol we can’t see it
