9x + 6y
3(3x + 2y)
Final answer:
The equivalent expression for 7x + 2x + 6y is 9x + 6y. We get this by combining the like terms 7x and 2x.
Explanation:
The expression 7x + 2x + 6y can be simplified by combining like terms. 'Like terms' are terms that have the same variables and powers. The terms 7x and 2x are like terms because they both have the variable x.
When you combine 7x and 2x, you add the coefficients (numerical parts) together. So, 7x + 2x equals 9x. Therefore the equivalent expression for 7x + 2x + 6y is 9x + 6y.

For the sake of showing work I will replace the empty space with an x like so...
To find out what x is you must cross multiply (aka butterfly)
***Image of this step is attached below
3*24 = 8*x
72 = 8x
Next divide 8 to both sides to finish isolating x. Since 8 is being multiplied by x, division (the opposite of multiplication) will cancel 8 out (in this case it will make 8 one) from the right side and bring it over to the left side.
72 ÷ 8 = 8x ÷ 8
9 = 1x
9 = x
To make these fractions equivalent the empty spot must be 9
Hope this helped!

Answer:
9
Step-by-step explanation:
Whatever you do to the denominator, you've got to do to the numerator, and vice versa. So for 8 to become 24, you multiply by 3. do that to the numerator 3 as well. 3 × 3 is 9.

Answer:
2.6 * bacteria
Step-by-step explanation:
We know that there are 20 million bacteria in 1 of coral reef. Let's write the number of bacteria in scientific notation with powers of 10:
Now let's write 1 in square meters, knowing that one cm equal 0.01 meter (
meters:
So now we can find how many bacteria there is in one of coral reef:
Number of bacteria in bacteria
we can now express 13000 in
knowing that 1 km = 1000 m =
m:
Since we know the number of bacteria per every of coral reef, the number of bacteria in
of coral reef will be the product of these two numbers:

The figure has the following symmetry:
A. line
B. point.
What is the order of rotational symmetry?
In Mathematics and Geometry, the order of rotational symmetry of any geometrical figure can be defined as the number of times in which the geometrical figure can be rotated around a full (complete) circle and still look the same.
As a general rule in geometry, a geometrical figure with number of sides (n) has "n" lines of symmetry and its order of rotational symmetry is equal to "n."
Based on the above rule, we can reasonably infer and logically deduce that the figure has both line symmetry and point symmetry.
