Answer:

at least 20 rows.

Step-by-step explanation:

when you add the students, teachers, and chaperones, it comes to 159. then you divide 159 by the number of seats each row has, so 159/8 = 19.875, you would have to round to the nearest whole number so 20 should be correct.

At a farm, there are two huge pits for storing hay. 90 tons of hay is stored in the first pit, 75 tons in the second pit. Then,
Travka [436]

Answer:

63 tons

Step-by-step explanation:

The problem statement asks for the tons of hay removed from the first pit. It is convenient to let a variable (x) represent that amount. This is said to be 3 times the amount removed from the second pit, so that amount must be x/3.

The amount remaining in the first pit is 90-x.

The amount remaining in the second pit is 75 -x/3.

Since the first pit remaining amount is half the second pit remaining amount, we can write the equation ...

... 90 -x = (1/2)(75 -x/3)

... 180 -2x = 75 -x/3 . . . . multiply by 2

... 105 - 2x = -x/3 . . . . . . subtract 75

... 315 -6x = -x . . . . . . . . multiply by 3

... 315 = 5x . . . . . . . . . . . add 6x

... 63 = x . . . . . . . . . . . . . divide by 5

63 tons of hay were taken from the first pit.

_____

<em>Check</em>

After removing 63 tons from the first pit, there are 27 tons remaining. After removing 63/3 = 21 tons from the second pit, there are 54 tons remaining. 27 is half of 54, so the answer checks OK.

Answer:

(11, -13)

Step-by-step explanation:

A is at (3, -5) and B is at (13, -15)

A point that is ⅘ of the way from A to B also divides the differences of the x-and y-coordinates in the same ratio.

For the x-coordinate,

x₂ - x₁ = 13 - 3 = 10

⅘ × 10 = 8  

 3 + 8 = 11

The x-coordinate of the point is x = 11.

For the y-coordinate,

y₂ - y₁ = -15 - (-5) = -15 + 5 = -10

⅘ × (-10) = -8

-5 + (-8)  = -13

The y-coordinate of the point is at y = -13.

The coordinates of the point are then (11, -13).

The diagram below shows the point ⅘ of the way from A to B.
