Answer:
14, 12
Step-by-step explanation:
the first is right I think
r+p=28 can also be written as 28-p=r
so 28-14=14
and 28-16=12
hopefully that works
Answer:
(6^-4)^-4, (6^-2)^-8, (6^8)^2
Answer: 108336
Step-by-step explanation:
given data:
cards on deck = 52
Since 2 queens are supposed to be in the 5 card hand. Therefore, 2 queens are choosen since we have a total of 4.
Since 2 Queens have been chosen already choosen. we are left with 3cards out of the hand of 5. This cards are to be choosen from the 48 remaining cards. Similarly same process would be used for other combination of playing cards.
(42∗483)+(43∗482)+(44∗481).
= (6 * 17296) + (4 * 1128 ) + (1 * 48)
= 103776 + 4512 + 48
=108336
Answer:
x = -(3 y)/2
Step-by-step explanation:
Solve for x:
-2 x - 3 y + 3/(x + y) - (3 x - 3 y)/(x^2 - y^2) = 0
Simplify and substitute z = x + y.
-2 x - 3 y + 3/(x + y) - (3 x - 3 y)/(x^2 - y^2) = -y - 2 (x + y)
= -y - 2 z:
-y - 2 z = 0
Multiply both sides by -1:
y + 2 z = 0
Subtract y from both sides:
2 z = -y
Divide both sides by 2:
z = -y/2
Substitute back for z = x + y:
x + y = -y/2
Subtract y from both sides:
Answer: x = -(3 y)/2
Answer:
The graph in the upper left
Step-by-step explanation:
We can answer this question by elimination.
The answer can't be the two graphs on the right, because the two lines will never cross.
It can't be the graph at the lower left, because this shows both cyclists starting at Mile 0.
It must be the graph in the upper left. It shows one cyclist starting 45 mi ahead of the other, with the faster cyclist catching up after about 2.5 h.
