If 160,000 divided by n = 4, find n

1 answer:

8 0

N = 40,000

To find the value of n, you want it to be on one side of the equation, and you want all the numbers to be on the other side. Starting out, this equation reads:

160,000/n = 4.

First, to get n out of the denominator (or bottom of the fraction), multiply both sides by n. On the left side, this will cancel out, leaving only 160,000. On the right side, you will now have 4n. So the equation should read:

160,000 = 4n.

To get n by itself, divide by 4 on both sides, leaving you with 40,000 = n.

Answer:

y=5/17x+17 3/17

Step-by-step explanation:

put the points on slope to get 5/17. then use point slope form (y-y1)=m(x-x1) and plug in 41 for x1, 81 for y1, and 5/17x for m

Corey has a piece of fabric that is 1/4 yard long. He cuts the length into 2 equal pieces. Write an expression for the length, i

MrRissso [65]

Answer:The length of each piece of fabric is 1/8 yards.

Step-by-step explanation:

Corey has a piece of fabric that is 1/4 yard long. He cuts the length into 2 equal pieces. This means that he cut 1/4 yards of fabric into two equal pieces.

An expression for the length, in yards, of each piece of fabric will be

Let the length of the fabric be x in yards. Also, let the length of each piece of fabric be y in yards. It becomes

y = x/2

Since x = 1/4

y =( 1/4)/ 2 = 1/4 × 1/2

y = 1/8

The length of each piece of fabric is 1/8 yards.

Need help asap or Im going to fail this class

nydimaria [60]

Answer:

The first four.

Step-by-step explanation:

There are 3 main postulates. SSS, SAS, and AAS. This simply refers to how we prove a triangle congruent. With SSS, all 3 sides must be congruent (either proven or given). AAS is when you have 2 angles congruent with a side next to one of the angles. NOT IN BETWEEN (there's an image as to what I'm talking about below). Finally, SAS. This is when you have a set of angles congruent with sides on each side congruent as well (look at the first four as an example of this.

Find the slope between the following points: (-5,2) and (3,9)

Kay [80]

Answer:

M=7/8

Step-by-step explanation:

The equation used to solve this is yz-y1/x2-x1.

This applied to the problem would look like 9-2/3--5

Simplified this would be, 7/8 as your slope

These 2 questions math 9th thanks! will give brainly!!

denis-greek [22]

Answer:

1) 25+7(n-1)

When the above 'n'(hours) is substituted on the equation, it equals up to the right cost.

2) Given that n represents the no.of bikes, you just plug it in to the equation below.

250+39(n-1)

= 250+39(20-1)

= 250+39*19

= 250+741

= 991
