Answer:

(0,5/3)

Step-by-step explanation:

3y+2x=-x+5

3y=-x-2x+5

3y=-3x+5

y=-x+5/3

if x=0 then y=-0+5/3=5/3

(x, y) =(0,5/3)

It is between 3.1 and 3.17 or 3.2 if you want it by hundredths.

This is because 3.16 is 3.1600000 and many more zeros but 3.16227766 is slightly over that so it would be between 3.1 and 3.17.

Sylvia plans to place 617 stamps in an album. Each page of the album holds 5 stamps. She uses division to find out how many full

bija089 [108]

Answer:

123 full pages

Step-by-step explanation:

Given

$Total\ Stamps = 617\ stamps$

$Each\ Page = 5\ stamps$

Required

Determine the number of full page

To do this, we simply divide the total stamps by stamps in each page;

$Pages = \frac{Total\ Stamps}{Each\ Page}$

$Pages = \frac{617}{5}$

$Pages = 123.4$

Then we record only the quotient

The quotient is the digits before the decimal

$Pages = 123$

<em>Hence, she has 123 full pages</em>

Answer:

840

Step-by-step explanation:

Given

$DJs = 7$

$To\ pick = 4$

Required

Determine the number of rankings

The term "ranking" as used in this question implies permutation and the required is calculated using:

$^nP_r = \frac{n!}{(n-r)!}$

Where

$n = 7$

$r = 4$

So:

$^nP_r = \frac{n!}{(n-r)!}$

$^7P_4 = \frac{7!}{(7-4)!}$

$^7P_4 = \frac{7!}{3!}$

$^7P_4 = \frac{7 * 6 * 5 * 4 * 3!}{3!}$

$^7P_4 = 7 * 6 * 5 * 4$

$^7P_4 = 840$

<em>Hence, number of ranking is 840</em>
