If x (x+y) = 27 and y (x+y) = 54, what is the value of (x+y)^2?

Answers

Answer:

9x^2

Step-by-step explanation:

It is given that:

x ( x + y ) = 27

If one manipulates the equation, by dividing by x, they get:

x + y = 27/x

It is also given that:

y ( x + y ) = 54

Again, manipulate the equation, only this time, divide by y,

x + y = 54/y

It is obvious that;

x + y = x + y

Yet this was proven;

x + y = 27/x

x + y = 54/y

Therefore, the following has to be true;

27/x = 54/y

To sove the proportion, use cross products;

27/x = 54/y

54x = 27y

Inverse operations:

54x = 27y

/27     /27

y = 2x

Substitute;

(x + y)

y = 2x

= (x + 2x)

= 3x

Now solve:

(3x)^2

9x^2

If x=27 and y=54, add them together then multiply by 2 and get 162

Pls help me out, I need to know what value of x makes this equation true

equation: 6(2x – 11) + 15 = 3x + 12

I have already found the answer to this equation (x = 7) but I need to know what value of x makes the equation true.

(If it's 7, my brain just needs a break from stuff, I've been up since 4 in the morning)

Answers

Answer:

x = 7

Step-by-step explanation:

12x - 66 + 15 = 3x +12

12x - 51 = 3x + 12

9x = 63

x = 7

6(2x-11)+15=3x+12
12x-11+15=3x+12
9x=9

X=1

The answer is that x is equal to 1

A circle has a diameter of 20 ft. What is the diameter? *

Answers

Since the question provided the diameter instead of radius, the diameter is 20 feet

Answer: well the diameter would be 20ft. If you meant to ask for the circumference then its 62.857ft

Step-by-step explanation:

Diameter of a circle is 20​ feet.

Hence it's Radius = 20/2 = 10 ft

We know circumference = 2πr

Circumference = 2 × 22/7 × 10 ft

Circumference = 44 × 10/7= 440/7

Circumference = 62.857 ft

14% of 120

[tex]\text{Explain in detail, please!}[/tex]
[tex]\big\text{:)}[/tex]

Answers

Answer:

16.8

Step-by-step explanation:

14% of 120 = 0.14 *120 = 16.8

14% of 120 is 16.8. Explanation: to get 10% of 120, simply move the decimal one place to the left. Getting 10% of something is the same as dividing it by 10 (120 divided by 10 is 12.). Now, to find 4% of 120, multiply 0.4 x 12 and you get 4.8. This is a hack to finding out percentages, simply take every number in 120 except for the last one, which is 0. That makes it 12. In order to make it balanced, we have to preform the same effect on 4, making it 0.4. (Oml this doesn’t make sense does it-) Example: to find 40 percent of 60, take every digit in those two number except for the last one, so 4 and 6. Then proceed to multiply them. If there is a one digit number, move the decimal one place to the left. I hope this math hack helps you in the future. Anyways, continuing. Now that we figured out 10% and 4% of 120, all that is left to do is add. 4.8 + 12 = 16.8. That is why 16.8 is the answer. (Kavlgdmgakgskgs this is way too long I hope I didn’t blabber on too much)

For Y

We use coordinate (-2, -4)

-4--2

For X

We use coordinate (0, -4)
