Answer:
so x=5y

reciprocal of x=1/x then

sum of reciprocals means 1/x+1/y=2/5

subsitute x=5y for x in 1/x+1/y=2/5 and get

1/5y+1/y=2/5

multiply 1/y by 5/5 to make it 5/5y so you can add since the denomenators (bottom number) are the same

1/5y+5/5y=2/5

6/5y=2/5

multiply both sides by 5y

6=2y

divide both sides by 2

3=y

put this into x=5y so

x=5(3)

x=15

y=3

reciprocal of x=1/x then

sum of reciprocals means 1/x+1/y=2/5

subsitute x=5y for x in 1/x+1/y=2/5 and get

1/5y+1/y=2/5

multiply 1/y by 5/5 to make it 5/5y so you can add since the denomenators (bottom number) are the same

1/5y+5/5y=2/5

6/5y=2/5

multiply both sides by 5y

6=2y

divide both sides by 2

3=y

put this into x=5y so

x=5(3)

x=15

y=3

Which expression is equivalent to 7 2/3⋅7 1/4?

140g of liquid A is and 128g of liquid B are mixed to make liquid C

work out the density of liquid C

density is defined as mass per unit volume

in this case liquids A and B with 2 different densities are mixed and we are asked to find the density of the liquid C

liquid A has a density of 0.7 g/cm³

mass of liquid A added is 140 g

therefore volume of liquid A added is - 140 g / 0.7 g/cm³ = 200 cm³

liquid B has a density of 1.6 g/cm³

mass of liquid B added is 128 g

volume of liquid B added is - 128 g / 1.6 g/cm³ = 80 cm³

the total mass of liquid C after adding liquid A and B = 140 g + 128 g = 268 g

total volume in liquid C - 200 cm³ + 80 cm³ = 280 cm³

density of liquid C = mass / volume

= 268 g / 280 cm³ = 0.957 g/cm³

density of liquid C - 0.957 g/cm³

ρ - density, m - mass, V - volume

Liquid A:

Liquid B:

Liquid C:

The density of liquid C is approximately 0.96 g/cm³.

To get the answer you would have to multiply fifty by .4 to get 20. now you know that 20 is 2/5 of the bad and 1/5 must be 10. So you would multiply 10 by 3 to get to 3/5 so you can have 60%. The final answer is 30

The **length** of a rectangular snow fort is 7 feet and the **width** of a rectangular snow fort is 5 feet.

Given that, Chris Built a rectangular snow fort with a perimeter of 24 feet.

The **perimeter** of a rectangle is the total distance of its outer **boundary**. It is twice the sum of its **length** and width and it is calculated with the help of the formula: **Perimeter** = 2(length + width).

Let x be the length of a rectangular snow fort and y be the **width** of a rectangular snow fort.

The **length** of the fort was 8 feet less than 3 times the width.

y=3x-8

Now, 2(y+x)=24

⇒ 3x-8+x=12

⇒ 4x=20

⇒ x=5

So, y=3x-8=7

Therefore, the **length** of a rectangular snow fort is 7 feet and the **width** of a rectangular snow fort is 5 feet.

We set up an equation for this. P = 2L + 2W.24 = 2(3W-8) + 2W

24 = 6W + 2W -16

32 = 8W

W = 4.

L = 3W-8

L = 3 (4) -8

L = 12-8

L = 4

24 = 6W + 2W -16

32 = 8W

W = 4.

L = 3W-8

L = 3 (4) -8

L = 12-8

L = 4

Well, one year is 365 days, and a leap year is every 4 years with an extra day, making leap years 366 days. 2016 is the nearest leap year. So, We take 365 from 1001 to get 636 days. Now it is January 1st 2016. So, subtract 366 from 636 to get 270 days. It is now January 1st 2017. There are 31 days in December, 30 in November, and 31 in October. Adding these together, you get 92. Subtracting 92 from 365, we get 273. So three days before October 1st is when you end. There are 30 days in September, so taking three away gives us the night of the 27th of September, 2017. So, the date you finish, if staying on a schedule of reading a bit each night, would be the night of September 27th, 2017, which is a Wednesday.

**Answer:**

**The retail price of the couch is $ 201.25.**

**Step-by-step explanation:**

Given, the wholesale price of the couch = $ 115,

Marked up rate = 75 %,

So, the total marked up = 75 % of wholesale price

= 75 % of $ 115

Hence, **the retail price of the couch** = The wholesale price + Total marked up

= $ 115 + $ 86.25

=** $ 201.25**

You would multiply the $115 by 1.75 to get $201.25 for the retail price
