Que es fraccion conbinadas

1 answer:

3 0

Como las fracciones representan números reales se mantiene la jerarquía de las operaciones de éstos.
Si no hay paréntesis, ni potencia y radicales, la mayor jerarquía la tiene la multiplicación o división que está más a la izquierda.
Se puede proceder eliminando una por una, de izquierda a derecha, todas las multiplicaciones y divisiones.

Find the equation of the line that passes throughP(6,0) andQ(1,−1).

yarga [219]

Answer:

Step-by-step explanation:

y=mx+b where m is the slope and b is the y intercept

m=(y2-y1)/(x2-x1), we have points (6,0) and (1,-1)

m=(-1-0)/(1-6)=1/5 so we have

y=x/5+b, using point (6,0) we can solve for b

0=6/5+b

b=-6/5

y=x/5-6/5 or more neatly

y=(x-6)/5

Answer:

Step-by-step explanation:

in tri ADC and tri BDC

∠ADC =∠BDC = 90

DC is common

AD = BD (given)

triangle ADC ≅ tri BDC by SAS congruency

hence AC = BC by CPCT ( congruent parts of congruent triangles)

hence, BC = 13

The senior classes at High School A and High School B planned separate trips to the indoor

Mazyrski [523]

Answer:

The number of students in each van are 7 and number of students in each bus are 23.

Step-by-step explanation:

Let the number of students in each van be 'x' and number of students in each bus be 'y'.

Given:

High School A:

Number of students = 132

Number of buses = 3

Number of vans = 9

As per question,

$9x+3y=132$ -------1

High School B:

Number of students = 205

Number of buses = 8

Number of vans = 3

As per question,

$3x+8y=205$ -------2

Multiplying equation (2) by -3 and adding the result to equation (1), we get:

$-3(3x+8y)=-3(205)\\-9x-24y=-615$

$-9x-24y=-615\\9x+3y=132\\---------\\-21y=-483\\y=\frac{-483}{-21}=23$

Now, plug in 23 for 'y' in equation (1) and solve for 'x'. This gives,

$9x+3(23)=132\\9x+69=132\\9x=132-69\\9x=63\\x=\frac{63}{9}=7$

Therefore, the number of students in each van are 7 and number of students in each bus are 23
