Answer:
9.0
Step-by-step explanation:
In a triangle, the midline joining the midpoints of two sides is parallel to the third side and half as long, so
3x-2 = 50/2
3x-2 = 25
3x = 25 + 2
3x = 27
x = 27/3
x = 9
Answer:
Sam made a mistake, and their correct value is 30.
Step-by-step explanation:
We must know that the are of the triangle is given by definition by
A = (1/2) * (b) * (h)
where
b = base
h = height
Substituting the values
A = (1/2) * (x) * (1 + 6x)
A = (1/2) * (x + 6x ^ 2)
Since the area is 13 then
(1/2) * (x + 6x ^ 2) = 13
Clearing x we have
6x ^ 2 + x = 26
6x ^ 2 + x-26 = 0
(x-2) * (x + 13/6) = 0
As we look for the base of a triangle then x> 0
x = 2
answer
the base is x = 2
6x ^ 2 + x = 26
Answer:
CT= $950
Step-by-step explanation:
Dado la siguiente información:
Servicio= $300 primeros dos
Servicio adicional= $150
Descuento= $100
<u>Para calculate el costo total, tenemos que usar la siguiente formula:</u>
CT= 300x + 150y - 100
x= costo normal
y= costo promocional
CT= 300*2 + 150*3 - 100
CT= $950
Answer:
z=4
Step-by-step explanation:
If z=x/y and x=10 and y=2.5 then,
z=10/2.5
10/2.5=4
