Answer:

Answer in simplified form is - 10 1/2 .

Step-by-step explanation:

We have given,

(5 1/4) ÷ (- 2 1/2)

This can be simplified as :

(5 1/4) ÷ ( -2 1/2)

Since 5 1/4 = 21/4  and -2 1/ 2 = -5/2

So we can write,

(5 1/4) ÷ ( -2 1/2) = 21/4 ÷ ( - 5/2)

or (21/4) / (-5/2)

or ( 21/4) * (-2/5)

or -42/20

or -21/10

or - 10 1/2 , this is the answer

Hence we get answer in simplified form as -10 1/2

What is the equation of this line?<br>y = -4×<br>y = 4×<br>y = - 1/4×<br>y = 1/4×​
sashaice [31]
The answer is the third choice: y=-1/4x.

We find this by remembering that slop is rise over run. Since the rise is -1 and the run is for we can make it -1/4 as the slope, which is next to the x term. Since the y intercept is at the origin we do not have a b term from the formula y=Mx+b.

Jaden’s teacher had 4 boxes of pens that each contained y pens. She took 6 pens out of one of the boxes and told her 17 students
Irina-Kira [14]

Answer:

x = (4y-6)/17

where x is the  number of pens each student got.

Step-by-step explanation:

No. of boxes = 4

no. of pen in 1 box = y

total no, of pens in 4 box =  No. of boxes *no. of pen in 1 box = 4y

No. of pen took away by Jaden's teacher = 6

no. of pens left = 4y - 6

This, 4y - 6 pen has to be divided among 17 students.

Let  each student get x pen

thus, total no. of pen got by 17 student  = 17x

This, 17x should be equal to total no. of pens available which is 4y-6

17x = 4y-6

=> x = (4y-6)/17

Thus, expression to represent  number of pens each student got

is x = (4y-6)/17
