Let a and o represent the numbers of apples and oranges sold the first week.
a + o = 108
Then the number sold the second week is
5a +3o = 452
Subtract 3 times the first equation from the second.
(5a +3o) -3(a +o) = (452) -3(108)
2a = 128 . . . . . . collect terms
a = 64 . . . . . . . . divide by 2
o = 108 - 64 = 44 . . . use the first equation to find o
64 apples and 44 oranges were sold the first week.
Answer: t=10
Step-by-step explanation:
FOIL 8(2t-6)= 16t-48
Combine like terms 3t+16t-48=2+14t becomes 19t-48=2+14t
Put all t's on same side 19t-14t=2+48
5t=50 Divide by 5 on each side to have t by self
Answer:
3/8.
Step-by-step explanation:
If you draw a tree diagram, it will make it easier.
For first draw, there is 10/16 chance of drawing red.
In the second draw, if not replaced, there is 9/15 chance of drawing red as one red is already drawn with 9 red beads left.
So, 10/16*9/15=3/8.
Answer:
h≤-19/6
Step-by-step explanation:
10 2/3 + 2h ≤ 4 1/3?
-10 2/3 -10 2/3
2h/-19/3≤ -19/3/-19/3
h≤-19/6
