(3ax + 4a) - (9x + 15a)

Answer:

In order to be considered a language, a system of communication must have vocabulary, grammar, syntax, and people who use and understand it. Mathematics meets this definition of a language. Linguists who don't consider math a language cite its use as a written rather than spoken form of communication

Answer:

The answer is b = 1/2

Step-by-step explanation:

1) Use this rule: a/b × c = ac/b.

[tex]5 = \frac{3 \times 3}{2} + b[/tex]

2) Simplify 3 × 3 to 9.

[tex]5 = \frac{9}{2} + b[/tex]

3) Subtract 9/2 from both sides.

[tex]5 - \frac{9}{2} = b[/tex]

4) Simplify 5 - 9/2 to 1/2.

[tex] \frac{1}{2} = b[/tex]

5) Switch sides.

[tex]b = \frac{1}{2} [/tex]

Therefor, the answer is b = 1/2.

Answer: C: 2(n+5)

Step-by-step explanation:

Answer:

Step-by-step explanation:

For finding we go from

Back to front that is,

First,

Sum of a number and 5 that is = n + 5

Then,

Twice of their sum that is = 2(n+5)

Hence,

Option C that is 2(n+5) (Ans)

Answer:

15, 30, 60, 120, 240, 480.

Step-by-step explanation:

You multiply the numbers by 2 to get to the next number.

For example, 15*2 is 30. 30*2 is 60. 60*2 is 120, etc..

Answer:

480

Step-by-step explanation:

In order to find the answer to this question you need to find the rule to the sequence and then add in till you get to the 6th term.

[tex]15,30,60[/tex]

Rule = each term doubles as it goes to the next term

[tex]15,30,60,120,240,480[/tex]

[tex]=480[/tex]

Hope this helps.

Answer:

C

Step-by-step explanation:

Answer:

x= −1 /2 y+4

Step-by-step explanation:

Let's solve for x.

2x+y=2(6−2)

Step 1: Add -y to both sides.

2x+y+−y=8+−y

2x=−y+8

Step 2: Divide both sides by 2.

2x /2= −y+8 /2 x= −1 /2 y+4

Answer:

A= 5278.34 in ²

Step-by-step explanation:

A= r² × 3.14 (pi)

Radius = Diameter ÷ 2

82 ÷ 2 = 41

41²= 1681

1681 x 3.14 = 5278.34

Answer:

C, D, F

Step-by-step explanation:

She walked 12 miles. Then she walked 1/4 that distance. "That distance" is 12 miles.

That means she walked 12 miles plus 1/4 of 12 miles.

She walked

12 + 1/4 * 12

You can factor out 12 from the expression above, and write it as

12(1 + 1/4)

Now you can do the addition in parentheses.

12(1 + 1/4) = 12(4/4 + 1/4) = 12(5/4)

Answer:

C, D, F

Answer:

12 + 1/4 x 12, 12 x 5/4, and 12 (1 + 1/4)

Step-by-step explanation:

To solve this, you need to add 1/4 of 12 to 12. 1/4 of 12 is 3, and 12 + 3 is 15. All of these equations are equal to 15, therefore they are all correct.

1/4 x 12 = 3 + 12 = 15

12 x 5/4 = 60/4 = 15

1 + 1/4 = 5/4

5/4 x 12 = 60/4 = 15

Step-by-step explanation:

Answer:

I did learn this before I'm not sure, but I think the answer is X x 10 = Y because on the chart for example X= 1 and Y= 10 so whatever number is on Y is basically X multiplied by 10. I hope this helps!

Hi, you've asked an incomplete question. However, I provided a brief explanation about surface areas.

Explanation:

Surface area is a term commonly used in mathematics, and other branches of science, and it basically refers to a calculation of the total space that an object occupies.

For example, you can find the surface areas of a cuboid using the formula:

[tex]6s^{2}[/tex] where s= side length.

Answer: 2

Step-by-step explanation: Add −3 and 5

Answer:

I think the answer for this question is B

Answer: BC = 54  <kjm=44

Step-by-step explanation:

1st 0ne-

if you look at it as 2 triangles with D being the shared side- I can determine that the angles are congruent (by SSA theorem)

so

6x=9x-27  (by corresponding parts of congruent Theorem)

-3x=-27

x=9

BC- 9(9)-27= 81-27=54

2nd one-

J bisects KJM

4x+6=3x+10

x=4

3(4)+10= 22

4(4)+6= 22

KJM= 22+22= 44

Answer:

Step-by-step explanation:

BD is the perpendicular disector of isosceles triangle DAC

AB=BC

6x=9x-27

3x=27

x=9

BC=9x-27=54

For triangle JKL and JML,

KL=ML

JL=JL

JK=JM from properties of right-angled triangle

So triangle JKL and JML are congruent

<KJL = <MJL

4x+6=3x+10

x=4

<KJL=4*4+6=22

Answer:

x = -24

Step-by-step explanation:

If you are to solve for x then multiply everything by 2 so

[tex]\frac{2x}{8}[/tex] - 1 = -7 now multiply everything by 8 to get rid of the fraction

2x - 8 = -56, solve for x so 2x = -48 so x = -24

Answer:

y is 8

Step-by-step explanation:

First u do 13y-9y=4y

so you then have 4y-5=27

then you plus 5 to 27

u then have 4y=32

then divide 32 by 4

so you will get y=8
