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

PLEASE HELP ASAP...i’ll mark brainlest

In a recent survey of 25 voters, 17 favor a new city regulation and 8 oppose it. What is the probability that in a random sample of 6 respondents from this survey, exactly 2 favor the proposed regulation and 4 oppose it?

9. 1/3(x+6) =815. 1/5(x+10)=620. 1/8(24x+32)=1032. 5-1/2(x-6)=433.2/3(3x-6)=3

What is an equation of the line in point-slope form?(3.8) and (7,5)

Find the Area of a circle if the radius is 5.2 cm. AGAIN: State the CORRECT formula, show the substitution and state your answer with the correct label.

I think it is called Euclidean geometry.

4x+3y=14

2y=6+4x

we can isolate the y in the second function

2y=6+4x

/2 /2

y=3+2x

then change all the y to 3+2x in first function

4x+3(3+2x)=14

4x+9+6x=14

10x=5

/10 /10

x=0.5 or 1/2

then fill the x in the function, get y.(each function will work)

2y=6+4x

2y=6+4(1/2)

2y=6+2

2y=8

y=4

x=0.5 y=4

2y=6+4x

we can isolate the y in the second function

x=0.5 y=4

**Answer:**

X-intercept: To find the x-intercept, set y to 0 and solve for x.

-x + 2(0) = 4

-x = 4

x = -4

So, the x-intercept is (-4, 0).

Y-intercept: To find the y-intercept, set x to 0 and solve for y.

-0 + 2y = 4

2y = 4

y = 4/2

y = 2

So, the y-intercept is (0, 2).

**Answer:**

**Step-by-step explanation:**

__Step 1: Cross-Multiply__

What cross multiply basically means is that you take both sides of the equation and you multiply my the opposite sides. So you take the top of the left fraction and multiply it by the bottom of the right fraction. You then have an equal sign and then have the bottom of the left fraction multiplied by the top of the right fraction.

__Step 2: Distribute__

__Step 3: Subtract 8x from both sides__

__Step 4: Divide both sides by 34__

The answer to your question would be X=1

cannonballs, as shown in the illustration. On an idle afternoon you decide to

calculate the number of cannonballs in the stack. What is the number of

cannonballs?

**650 **is the number of **cannonballs**. It typically fires a projectile propelled by an explosive chemical.

A **cannon **constitutes a large-caliber gun that belongs to the artillery category. It typically fires a **projectile **propelled by an explosive chemical. Prior to the development of smokeless powder in the late 19th century, gunpowder (sometimes known as "black powder") served as the main propellant.

Depending on their intended purpose on the battlefield, different types of gun combine and balance these characteristics to differing degrees. **Cannons **differ in gauge, effective range, mobility, rate of fire, angle of fire, and firepower. A large artillery weapon is a cannon.

By utilizing the formula of a square pyramid,

n(n+1)(2n+1)/6

12(12+1)(2(12)+1)/6

12(13)(25)/6

2*13*25

=**650**

Therefore, **650 **is the number of cannonballs.

You are Miguel Cervantes de Navas y Colon, captain in the Royal Spanish

Army in Sevilla in the year 1842. Outside your barracks window is a stack of

cannonballs, as shown in the illustration. On an idle afternoon you decide to

To find the simplest form of a fraction, you have to find the greatest common factor (GCF). To do so, list out the factors of the numerator (28) and the denominator (35) and find the biggest common number between the two numbers.

Factors of 28: 1, 2, 4, 7, 14, 28

Factors of 35: 1, 5, 7, 35

Out of those factors, we can see that 1 and 7 are the common factors, but 7 is the greatest which makes it our GCF.

Now we can divide the numerator and the denominator by the GCF to receive our simplest form.

28 ÷ 7 = 4

35 ÷ 7 = 5

Rewrite the fraction with the new numerator (4) and the new denominator (5).

The simplest form is:**4/5 **or **0.8**.

Factors of 28: 1, 2, 4, 7, 14, 28

Factors of 35: 1, 5, 7, 35

Out of those factors, we can see that 1 and 7 are the common factors, but 7 is the greatest which makes it our GCF.

Now we can divide the numerator and the denominator by the GCF to receive our simplest form.

28 ÷ 7 = 4

35 ÷ 7 = 5

Rewrite the fraction with the new numerator (4) and the new denominator (5).

The simplest form is:
