Answer:

0 = 0

Step-by-step explanation:

<u>Subtract </u><u>4</u><u> from both sides of the equation</u>

3 + 4 − 4 = 3 + 4 − 4

<u>Simplify</u>

<u>Subtract the numbers</u>

3 = 3 + 4 − 4

3 = 3

<u>Subtract </u><u>3x</u><u> from both sides of the equation</u>

3 − 3 = 3 − 3

<u>Combine like terms</u>

0 = 3 − 3

<u>Result</u>

0 = 0

Help me for brainlist no cap
Schach [20]

Answer:

C

Step-by-step explanation:

So first, you find the area of a rectangle, which would be 15 * 30 = 450. Next, find the area of the semicircle by doing \pi *r^2 / 2 (you have to divide by 2 because it's only have a circle).

The radius is half of 15, so 15 / 2 = 7.5. This would be:

\pi * 7.5^2 / 2

=\pi * 56.25 /2

=28.125\pi

=28.125*3.14=88.3125

The last step is to add 450 + 88.3125 = about 538.3 m^2

mart [117]

Answer:

11

Step-by-step explanation:

Luke has a square patio, which means each side must have the same amount of tiles.

For example, he could have a 4 by 4 patio, 5 by 5, etc.

121 happens to be the square of 11. In other words, 11*11=121!

So, Luke can fit 11 tiles along each side of his patio.

Agatha is five times older than her son bob. three years ago she was nine times older. how old is agatha?
Naya [18.7K]
Write an equation system based on the problem
"Agatha is five times older than her son, Bob" could be written as:
  a = 5b.......(first equation)
"Three years ago, she was nine times older" could be written as:
  a - 3 = 9(b - 3)......(second equation)

Solve the equation system
To find the value of b, substitute 5b as a to the second equation
a - 3 = 9(b - 3)
5b - 3 = 9(b - 3)
5b - 3 = 9b - 27
5b - 9b = -27 + 3
-4b = -24
   b = -24/-4
   b = 6
Her son, Bob, is 6 years old

To find Agatha's age, substitute the value of b to the first equation
a = 5b
a = 5 × 6
a = 30
Agatha is 30 years old

What does x+2/5=12 equal and I would love to Seehow you worked it out
sladkih [1.3K]

You said                      x + 2/5 = 12

It might be easier to handle if we use the decimal for 2/5.

                                               x + 0.4 = 12

Subtract 0.4 from each side:  x = 11.6

That's all there is to it.  I'm sorry I can't make it
more complicated for you.
