The question in English
A company replaces its computers with more modern ones. New computers are two thirds of the total and there are 33 more of them than old computers. How many computers does the company have? How many computers are new?
Let
x-------------> numbers of new computers
y-------------> numbers of old computers
we know that
x=y+33--------> equation 1
x=(2/3)*(x+y)--------> x-(2/3)x=(2/3)y----------> (1/3)x=(2/3)y
x=2y----------> equation 2
1=2
y+33=2y--------> 2y-y=33---------> y=33
x=2y------> x=2*33----------> x=66
x+y----------> 66+33---------> 99 totally computers
the answers are
Part A) the company have 99 computers
part B) The numbers of new computers are 66
the answer in spanish
Hacemos
x-------------> numero de computadoras nuevas
y-------------> numero de computadoras viejas
sabemos que
x=y+33--------> ecuacion 1
x=(2/3)*(x+y)--------> x-(2/3)x=(2/3)y----------> (1/3)x=(2/3)y
x=2y----------> ecuacion 2
1=2
y+33=2y--------> 2y-y=33---------> y=33
x=2y------> x=2*33----------> x=66
x+y----------> 66+33---------> 99 computadoras en total
Las respuestas son
Parte A) la empresa tiene un total de 99 computadoras
Parte B) El numero de computadoras nuevas es 66
Answer:
ABC
Step-by-step explanation:
They are on the same line.
Answer:
x - y + 6 = 0
Step-by-step explanation:
In normal form of a straight line, the equation is given by
where p is the perpendicular distance of the line from the origin and
is the angle between the perpendicular line and the positive direction of the x-axis.
Here, in our case
and
Degree,
Therefore, the normal form of the straight line equation is
⇒
⇒
{Since, Cos (180 - Ф) = - Cos Ф and Sin (180 - Ф) = Sin Ф}
⇒
⇒ - x + y = 3√2 × √2 = 6
⇒ x - y + 6 = 0
So, the standard form of the equation is x - y + 6 = 0. (Answer)
Answer: C) Alternate interior angles
The blue angles marked are inside the parallel lines, so they are considered interior. They are on alternating sides of the transversal line. The angles are only congruent when the lines are parallel.
If you divide 189 by 8 you would get 23.625 but first you have to subtract 13 from 189 (176) then divide it (22) the answer is 22 dollars
