Honestly I can see an argument for 7 shelves or for 8 shelves. 

When you do the calculation; \frac{422}{59}=7.15 You get 7.15 shelves. Clearly you cannot have .15 of a shelf so the logician in me wants to say you need 8 shelves! 

But if the assignment is aimed estimation skills, (Which is what I assume is being implied by the title of the assignment), then the easier calculation of \frac{420}{60}=7 is probably what the teacher was hoping for.

You might have been accidentally been calculating \frac{59}{422} =.139. Remember division is NOT communitive! i.e.1\div2\neq2\div1.

From the image;
The first step was to see that 59 can not go into 4..resulting in the zero above the 4, multiplying 0 by 59 and subtracting 0 from 4. 

The second step begins by bringing down the 2, seeing that 59 can not go into 42..resulting in the zero above the 2, multiplying 0 by 59 and subtracting 0 from 42.

The third step begins by bringing down the 2, seeing that 59 can go into 422 7 times (I tested this on the right by a short multiplication problem)..resulting in the 7 above the 2, multiplying 7 by 59 and subtracting 413 from 42.

This process continues....

\frac{422}{59}\approx7.15
You have to round it up. So it will be 8 shelves.

Convert the equation to slope-intercept form: 2y = x + 8
nalin [4]

Answer:

y=(1/2)x+4

Step-by-step explanation:

Since slope-intercept form is y=mx+b, all we need to do is divide both sides by 2:

2y=x+8

y=1/2x+4

Thus, the equation would be y=1/2x+4

How to solve -c(11c + 4)
saul85 [17]

Answer:

-11c^{2} - 4c

Step-by-step explanation:

You have to distribute the -c to both of the numbers in the parentheses, so the eleven would become negative, and c multiplied by c is c squared. The positive 4 becomes negative 4, and 4 times c is 4c. Hope that helps!
