Answer:
D
Step-by-step explanation:
You have -5 1/2 to find the complete opposite all you have to do is take away the negative sign and find the number on the number line.
<span>xy = k
solve for k...
(8) * (8/3) = (64/3) = k
y = k / x
when x = 4,
y = (64/3) * (1/4) = (16/3)
Hope this helps!

6 times 6 equals 36 and 3 time 12 equals 36!
Hope it helps!
Answer:
Barbara's speed in clear weather is and in the thunderstorm is .
Step-by-step explanation:
Let be the speed and be the time Barbara drives in clear weather, and let be the speed and be the time she drives in the thunderstorm.
Barbara drives 22 mph lower in the thunderstorm than in the clear weather; therefore,
(1).
Also,
(2).
(3). ,
and
(4).
From equations (2) and (3) we get:
putting these in equation (4) we get:
and substituting for from equation (1) we get:
This equation can be rewritten as
which has solutions
We take the first solution because it gives a positive value for
.
Thus, Barbara's speed in clear weather is and in the thunderstorm is .
Hello, well there are a few ways to write this. Here is one outlook.
Bruce bought three boxes of tiles with the same number of tiles in each.
x = number of tiles
3 = number of boxes
3x = total number of tiles.
Make note, the problem is asking for an expression for how many tiles he used and not the total number of tiles he has. Anyways, the problem then tells us he had to go get 3 more boxes but he used only 2 tiles out of the last box. So he used 2x + 2 tiles We put this together and we have
3x + 2x + 2
5x + 2
Number of tiles Bruce used = 5x + 2
We do the same for Felicia:
She gets 5 boxes, which = 5x. Then she had to go back and just get 5 tiles. So we have:
5x + 5
Number of tiles Felicia used = 5x + 5
