Answer:

360 - Y

Step-by-step explanation:

From the information provided in the question, we will understand that the question lacks detailed information.

Given that:

The total number of actual students on the A honor roll = 360

To find the number of students on the A honor roll of 8th graders;

Let denote Y to represent the total number of students who exist on the A honor roll except for the 8th graders.

Then:

The number of 8th graders = all number of students on are on the A honor roll - Y

The number of 8th graders = 360 - Y

If Y is known, then the number of the 8th graders can be fully determined.

kvv77 [185]
Answer: ( -7 , -3 )


Step by step:
The point: ( X , Y )
Left 2 units = change X by -2
So, -5 subtract by 2 equals -7
Down 3 units = change Y by -3
So, 0 subtract by 3 equals -3
Now, X = -7 and Y = -3, so the answer is ( -7 , -3 )


Hope this helps! Please tell me if I did anything wrong, thank you!

What’s the correct answer for this?
kondor19780726 [428]

A(-3,5) to B(8,1)

That makes a right triangle 8 - -3 = 11 in the x direction, 5 - 1 = 4 in the y direction.

d² = (8 - -3)² + (1 - 5)² = 11² + (-4)² = 121 + 25 = 146

d = √146 = 12.083045973594572

A 40-inch board is to be cut into three pieces so that the second piece is 3 times as long as the first piece and the third piec
tiny-mole [99]

Answer:

The first piece is 5 inches long, while the second is 15 inches and the third one is 20 inches.

Step-by-step explanation:

To determine the length of the 3 pieces, knowing that the total of the board is 40 inches, and that the second measures 3 times more than the first and the third measures 4 times more than the first, the following equation must be performed:

X + 3X + 4X = 40

8X = 40

X = 40/8

X = 5

Therefore, the first piece is 5 inches long, while the second is 15 inches and the third 20 inches.
