Answer:
x = 7.5
Step-by-step explanation:
Since the midsegment and the third segment of the triangle are parallel to each other, therefore,



Cross multiply


Subtract 24 from each side
54 - 24 = 4x
30 = 4x
Divide both sides by 4
30/4 = x
7.5 = x
x = 7.5
Answer:
x-3
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
Let's give letters as the image. Triangle ABH is a right triangle, so you can apply pythagoream theorem. In particular, it's the classic "3-4-5" triangle (there are some triplets of integers that gives you a right triangle, and 3-4-5 is the most famous). Either way, the height of the triangle is 4.
At that point you can compute the area by multiplying base and height, and the total surface is 16.
The answer is A, vertical is x=-2 and y=0.
Answer:
Step-by-step explanation:
Let us represent:
Short pieces = x
Middle pieces = y
Long pieces = z
A three foot long deli sandwich must be split into three pieces
x + y + z = 3
The middle piece is twice as long as the shortest piece
y = 2x
The shortest piece is 8 inches shorter than the longest piece.
x = z - 8
z = x + 8
We substitute
x + y + z = 3
x + 2x + x + 8 = 3
5x = 8 - 3
5x = 5
x = 5/5
x = 1
y = 2x
y = 2 × 1
y = 2
z = x + 8
z = 1 + 8
z = 7
How long should the three pieces be?
