Answer:

7

Step-by-step explanation: Trust me

Answer:

Calculate the average of the five original cards:

2+5+7+8+9=31

31/5 = 6.2

So, if a card was removed, the four remaining cards would have an average of 6, meaning that they would add up to 24.

31-x=24?

Subtract 31 from both sides: -x=-7

Divide by -1 on both sides: x=7

So, we know that 7 was removed.

Answer:

try 87 or 86

Step-by-step explanation:

Answer:8/6 and 4/3

Step-by-step explanation:

Quite simple. Just count the amount of squares, which is 8. Now do the same for the triangles, which is 6.

So 8/6

You can also reduce that by dividing it my 2 so it is now 4/3

So click both 8/6 and 4/3

Answer:

radius: 3 units <----> Circumference: 18.84 units

Diameter: 12 units <----> Circumference: 37.68 units

Diameter: 36 units <----> Circumference: 113.04 units

Radios: 5 unites <----> Circumference: 31.4 units

Step-by-step explanation:

How I got the answers for the radiuses:

3 (this is only half the diameter so if you do 3 x 2 you will get the diameter.)

3 x 2 = 6

C = pi x d

C = 3.14 x 6

C = 18.84 [this is the first radios]

5 (this is only half the diameter so if you do 5 x 2 you will get the diameter.)

5 x 2 = 10

C = pi x d

C = 3.14 x 10

C = 31.4 [this is the second radios]

How I got the diameters:

12 (this is the full diameter so we do not have to multiply it by 2)

C = pi x d

C = 3.14 x 12

C = 37.68 [this is the first Diameter]

36 (this is the full diameter so we do not have to multiply it by 2)

C = pi x d

C = 3.14 x 36

C = 113.04 [this is the second Diameter]

Answer:

{-2,-1,0,1,2}

Step-by-step explanation:

When we are talking of the range, we are referring to the possible y-values the relation can take

Hence, a set of y-values will represent the range of the relation

we have this as:

{2, 1 , 0, -1 , -2}

Arranging in order, we have ;

First, what is an equation?

➳ A mathematical statement which shows that two algebraic expressions are equal is called and equation.

Or, LHS = RHS

Example:- 3x - 5 = x + 8

An equation is said to be a linear equation if it contains only one variable (literal) with highest power 1.

_______________________

Solving an equation:-

To solve the equation x + 5 = 7 means to find the value of an unknown algebraic quantity used in the equation.

Example:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ Rules for solving an equation by the substitution method:-

Rule ❶ 

If x = 2, the value of the expression 3x + 2 = 3 × 2 + 2 = 6 + 2 = 8

Rule ❷

If x = 0, the value of the expression 3x + 2 = 3 × 0 + 2 = 0 + 2 = 2

Rule ❸ 

If x = -2, the value of the expression 3x + 2 = 3 × -2 + 2 = -6 + 2 = -4

Now consider the algebraic expression 5x - 2y

This expression consists of variables x and y.

Now if :-

The process of finding the value of an algebraic expression by substituting the given value of its variable is called substitution.⠀⠀

Answer: 20 meters  

Step-by-step explanation:

Answer:

8 sq units

Step-by-step explanation:

area of square in middle is 2 x 2 = 4 sq units

area of one triangle is 1/2(2)(2) = 2 sq units

however, there are two triangles, so you have to double 2 to get 4

4 + 4 = 8

Answer:

8cm^2

Step-by-step explanation:

Method 1: It's a trapezium, so take the top length, (6cm), add it to the bottom length (2cm) = 8cm which is then divided by 2 (4cm) then multiplied by the height (2cm) giving an area of 8cm squared.

Method 2: area of the square = 2 x 2 = 4cm^2

Triangle 1: 2 x 2 = 4, divided by 2 = 2cm^2

Triangle 2: same as triangle 1.

Total: 4 + 2 + 2 = 8cm^2

Answer:20.5

Step-by-step explanation:if you measure it with grid paper and round it its 20.5

Answer:

14.4 centimeters

Step-by-step explanation:

The formula for circumference is: [tex]2\pi r[/tex]. In this case, the r (radius) is 2.3. Multiply it by 2 to get the diameter or 4.6. Then multiply 4.6 x [tex]\pi[/tex] (pi) to get 14.444. This rounded to the nearest tenth of a centimeter is 14.4.

Note:

I used 3.14 for [tex]\pi[/tex] (pi).

Answer:

(A) 5th day: 405 views

(B) inductive

Step-by-step explanation:

Each day the views get multiplied by 3.

Answer:

A. I would expect the video to have 405 views after day 5. There is a pattern of the number being multiplied by 3.

B. Deductive reasoning

Step-by-step explanation:

(This is really going to explain BOTH questions at the same time)

Looking that the problem, the number of views keep going up. There is a multiplier behind this, we just don't know WHAT multiplier it would be. To find that out, divide 1 value by the one before it. I'll do 135 divided by 45 as an example. That would equal three. Now we know the multiplier is 3. So, now we need to multiply 135 by 3 to get 405 views after five days.

(This is really summarizing B, whilst answering A.)

Mixed number is the combination of the whole number and the fraction number. The whole and the part of the whole combined can be expressed as a mixed numbers. the result of the division of the two mixed number is [tex]3\dfrac{3}{16}[/tex].

Given information;

The mixed numbers given is the problem are  [tex]8\dfrac{1}{3} [/tex]  and [tex]2\dfrac{2}{3} [/tex]

Mixed number is the combination of the whole number and the fraction number. The whole and the part of the whole combined can be expressed as a mixed numbers.

Now the given mixed number has to be divided. This number can be divided by converting into the proper fraction numbers. Let I is the result when the two numbers are divided. Thus,

[tex]x=8\dfrac{1}{2} \div 2\dfrac{2}{3} \\ [/tex]

To solve this convert the mixed numbers into the fraction number. For this multiply the denominator to the whole number and then add in the numerator. Thus,

[tex]x=\dfrac{16+1}{2} \div \dfrac{6+2}{3} \\ x=\dfrac{17}{2} \div \dfrac{8}{3} \\ [/tex]

Convert the divide sign into the multiply sign by changing the numerator to the denominator of one of the fraction.

[tex]x=\dfrac{17}{2}\times \dfrac{3}{8} \\ x=\dfrac{51}{16}\\[/tex]

As 16 can divide the number 51 in 3 times with reminder 3. Thus the mixed number for the above fraction can be written as,

[tex]x=3\dfrac{3}{16}[/tex]

Thus the result of the division of the two mixed number is [tex]3\dfrac{3}{16}[/tex].

Answer:

21a-14b

15b-20a

Step-by-step explanation:

Answer: a + 3b

Step-by-step explanation:

Okay, so...

7(3a - 2b) = 7(3a) - 7(2b) ... distributive property

21a - 14b

5(3b - 4a) = 5(3b) - 5(4a) ... distributive property

15b - 20a

(21a - 14b) + (15b - 20a) = 21a -12b + 15b - 20a =
