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

The true statement regarding selling stock at 25 1/4, which you bought at 20 1/4, is C. You'll make a profit of $150. You bought 30 shares at 20 1/40. 30 * 20 1/4 = 30 * 81/4 = 2430/4. You sold 30 shares at 25 1/4. 30 * 25 1/4 = 30 * 101/4 = 3030/4. So you earned more than you paid for them. The value you earned is 3030/4 - 2430/4 = (3030-2430)/4 = 600/4 = 150. So, you'll make a profit of $150.

The volume of each celluloid die is (.25 x .25 x .25) = 0.015625 cubic inch.

To manufacture 24,000 of them, you need to start with__at least__

(24,000) x (0.015625) =__375 cubic inches__.

I don't know how celluloid is sold, so you should also keep in mind that

375 cubic inches = about 207.8 fluid ounces, or about 6.5 quarts.

I'm sure a bit more than that was used in the manufacture, since

there's always some wasted, spilled, or trimmed off of the edges.

The letter H is the only one in the word "happy" that has the rotational simmetry on the order of two. In fact, if you rotate the letter H 180° clockwise or counterwise, it will still look the same; it is called "on the order of two", exactly because you've rotated it 180° (two rotations of 90°).

Letter H

The order of symmetry is the number times an object appears exactly the same when rotated about a certain axis.

From the word HAPPY, only letter H will have 2 order of symmetry.

When rotated at 180°, It will look exactly the same.

A, P, P and Y have only 1 order of symmetry.

**Answer:**

2y=8/3x

**Step-by-step explanation:**

The** equation** for making y loaves of bread with x cups of flour is x = (4/3) * y.

To find the equation for making y loaves of bread with x cups of flour, we can set up a **proportion** using the given information. If Mr. M uses 8/3 cups of flour to make 2 loaves of bread, the equation would be:

(8/3 cups)/(2 loaves) = (x cups)/(y loaves)

Cross multiply and solve for x:

8/3 * y = 2x

Simplify the equation to:

4/3 * y = x

So, the equation for making y loaves of bread with x cups of flour is:

x = (4/3) * y

**Answer:**

○ C. The lines are perpendicular.

**Step-by-step explanation:**

In order for equations to be **perpendicular**,their *rate of changes* [*slopes*] must be **OPPOSITE***MULTIPLICATIVE*** INVERSES**, which in this case is so:
