Answer:
a muffin costs 2.20 and a quart of milk costs 90 cents.
8x +7y = 39 multiply everything by 2
2(8x +7y = 39)
16x +14y = 78
+4x - 14y= -68
-------------------------
20x = 10
20x /20 = 10/20
x = 1/2
Plug x into first formula
8 x + 7y =39
8(1/2) 7y=39
4+ 7y =39
4-4+7y =39-4
7y =35
7y/7 = 35/7
y = 5
(1/2, 5)
If a fair coin is tossed three times, sample = 2^3 = 8 (hhh, hht, hth, thh, htt, tht, tth, ttt) where h=head and t=tail.
Probability of getting one:
Outcomes with one head (h) = 3
P(1 h) = 3/8 = 0.375
(355*7)+2
=-2,487
(92*7)+4
648
2,487-648
1839/7
=262 and 5/7
Hopefully this helps you
Answer:
I would say Sony's age is 33 because 4/5 of 32 is about 25 then 25+8=33
Hope I helped :)
