Answer:

12x+4

Step-by-step explanation:

We can solve this by using PEMDAS (parentheses exponents multiplication division addition subtraction) to solve this in the correct order:

4+8÷2x (6-3)

So first we solve (6-3) since it’s in parentheses:

4+8÷2x (3)

Now we multiply 3 times 8/2x:

4+8/2x(3)

4+12x

(Put in order)

12x+4

And that^ is the answer because we cannot simplify any further!

Hope this helps :)

jeanine Baker makes floral arrangements. She has 13 different cut flowers and plans to use 7 of them. How many different selecti

Ksju [112]

A total of 1,716 selections of the 7 flowers are possible.

Step-by-step explanation:

Step 1:

There are 13 flowers from which Jeanine Baker plans to use 7 of them.

To determine the number of selections that are possible we use combinations.

The formula for combinations is; $^{n} C_{r}=\frac{n !}{(n-r) ! r !}$ .

Step 2:

In the given formula, n is the total number of options and r is the number of options to be selected.

For this question, $n = 13$ and $r=7$ .

So $^{13} C_{7}=\frac{13 !}{(13-7) ! 7 !} = \frac{13 !}{(6) ! 7 !} = 1,716.$

So a total of 1,716 selections are possible.

Write the algebraic expression described. Recall that two angles are complementary if their sum is 90 degrees. If one angle meas

igor_vitrenko [27]

Answer:

C = 90 - d

Step-by-step explanation:

We know that the sum of complementary angles is 90 degrees

i.e.

Angle 1 + angle 2 = 90°

As it is stated in the question that one angle is d then

d+C = 90

where C is complementary angle of C

This can also be written as:

C = 90 - d ..

This pattern follows the rule add 2. What is another feature of this pattern?

Murrr4er [49]

Answer:

Option D, All of the terms are odd

Step-by-step explanation:

According to the image description provided:

Term one starts with one dot. One is an odd number.

If you add two to an odd number, the sum would be another odd number. This is what's happening with the pattern.

For example:

$3+2=5$

Three is an odd number. If you add two to it, you would get five, which is another odd number.

Term two has 3 dots, term three has 5 dots, term four has 7 dots.

So, all terms should be odd.

Option D should be the correct answer.

One of the acute angles in a right triangle is 89. What is the measure of the other acute angle?

yuradex [85]

Answer: The other acute angle is 1 degree

Step-by-step explanation:

Since a triangle must add up to 180 degrees, and it's specifically a right triangle, you know that one other angle is 90 degrees. Since you have 89, and 90, all you have to do is simply add them together, which gives you 179. This means the remaining angle must be at 1 degree.

Hope this helps!
