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

Y=7-|x| find y if x = 2

Somebody please help ASAP!!!!

At Noise Pollution Cellular, plan A is $30.00 per month and $5.00 for every gigabyte of data. Plan B is $50.00 per month and $2.00 for every gigabyte of data used. Irfan wants to find out which plan is the best choice for him. On average, he uses five to eight GB of data per month.How much data would Irfan need to use for both plans to cost the same?

What is the difference between points a (1,2) and b (9,17)

I'm making a great dodecahedron for geometry and I'm failing at putting it together! Any tips?!

r = a + k/b

a = r - k/b

a = 1/b (r.b - k)

a = r - k/b

a = 1/b (r.b - k)

The **amount **of concrete that will be required for the driveway is **151200 cubic inches**.

**Volume** is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write** volume** as -

V = ∫∫∫ F(x, y, z) dx dy dz

Given is that a **driveway** is 10 feet long, 15 feet wide, and 7 inches deep.

The amount of concrete that will be required for the driveway will be equal to the volume of the driveway.

V = 10 x 12 x 15 x 12 x 7

V = 120 x 180 x 7

V = 21600 x 7

V = 151200 cubic inches

Therefore, the **amount **of concrete that will be required for the driveway is **151200 cubic inches**.

**Answer:**

88

**Step-by-step explanation:**

V=l x w x h

(10) (15) (.58) = 87.5. Rounding=88

remember it's 7 inches not feet. 7/12=.58

Seven times the sum of a number and 5 equals 2.

Answer: 7(x + 5) = 2

Step-by-step explanation:

Use the variable x to represent the number

7(x +5) = 2

**Answer:**

7(x+5)=2 x= -33/7

**Step-by-step explanation:**

**Answer:**

Explanation:

There is a theorem in geometry that says:

In a circle, if two chords are equal in measure, then their corresponding minor arcs are equal in measure.

Those small tick marks on each of the chords means that they are equal in measure. So, following the theorem, the arcs are also equal in measure.

If they are equal and

arc AB = arc CB

arc AB = 24 feet

Then

arc CB = 24 feet

by substitution.

Given:

62 feet of fencing = perimeter

P = 2 (L + W)

62/2 = 31

16 + 15 = 16 * 15 = 240 ft²

17 + 14 = 17 * 14 = 238 ft²

18 + 13 = 18 * 13 = 234 ft²

19 + 12 = 19 * 12 = 228 ft²

20 + 11 = 20 * 11 = 220 ft²

The best dimensions that will give the greatest area is to have a length of 16 feet and a width of 15 feet.

solve for x

As we can see

x+32=90

x= 90-32

x= 52
