Step-by-step explanation:

Answer:

26

Step-by-step explanation:

2 squares + 3 circles = 31. So, the sum of the squares is divisible by two, and the sum of the circles is divisible by 3. Then, I used trial and error to figure out that the square's value is five, and the circle's value is seven. 5 + 7 + 7 = 19. 27 - 19 = 8. The triangle's value is eight. 5 + 7 + 12 = 24. It works. 15 + 7 + 4 = 26

The sum of the shapes in the fourth row is 24 and this can be determined by using the arithmetic operations and by forming the linear equations.

Given :

In the diagram, each shape has a value and the sums of the shapes in each of the first three rows is given.

Let the symbol of the circle be denoted by 'x', square be denoted by 'y', and triangle be denoted by 'z'.

Now, the linear equations that represent the given diagrams are:

2y + 3x = 31   --- (1)

y + 2x + 3z = 27   --- (2)

3y + x + z = 24    --- (3)

Now, evaluate equation (1) for 'y'.

[tex]\rm y=\dfrac{31-3x}{2}[/tex]  --- (4)

Now, substitute the value of y in equation (2).

[tex]\rm \dfrac{31-3x}{2}+2x+3z=27[/tex]

31 - 3x + 4x + 6z = 54

6z = 23 - x

[tex]\rm z = \dfrac{23-x}{6}[/tex]    --- (5)

Now, substitute the value of 'y' and 'z' in equation (3).

[tex]3\times \dfrac{31-3x}{2}+x+\dfrac{23-x}{6}=24[/tex]

[tex]279-27x+6x+23-x=144[/tex]

158 = 22x

[tex]x = \dfrac{79}{11}[/tex]

Now, substitute the value of x in equations (4) and (5).

[tex]\rm z = \dfrac{23-\dfrac{79}{11}}{6}[/tex]

[tex]z = \dfrac{29}{11}[/tex]

[tex]\rm y=\dfrac{31-3\times \dfrac{79}{11}}{2}[/tex]

[tex]y=\dfrac{52}{11}[/tex]

The last equation is written in terms of x, y, and z as:

= 3y + x + w

Now, substitute the value of known terms in the above equation.

[tex]=3\times \dfrac{52}{11}+\dfrac{79}{11}+\dfrac{29}{11}[/tex]

[tex]=\dfrac{156+79+29}{11}[/tex]

= 24

Step-by-step explanation:

its b  because x+6 never changes

Answer:

1. 5x = 10

5x-1 = 9

2. 5x = 50

5x-1 = 49

3. 5x = 60

5x-1 = 59

4. x = 5

5x-1 = 24

5. x = 7

5x = 35

6. x = 20

5x = 100

Step-by-step explanation:

substitution x in each one

for example

x = 2

5x = 5×2 (×2 because x = 2)

so, 5x = 10

Answer:

You need to look at the value of x which is already given and insert it into the other values

Step-by-step explanation:

fore example

                                        if x=2                  

then        5x                                       5x-1

              5(2)                                     5(2)-1

            = 10                                       10-1

                                                          =9                                                          

(you put the value of x where x is supposed to be, since x was 2 I replace it with 2 and got the answer).

where we have value of 5x which is 25 we will substitute to get value of x.

5x= 25

x= 25/5

x= 5

Now we have the value of x

Where we have the last value we will substitute it like

5x-1= 34

5x= 34+1

5x= 35

x= 35/5

x= 7

Now we have value of x

Answer:

= 105(x+2)/33-x

Step-by-step explanation:

Given the expression

[3(x+2)*10*7]÷70 - 2(x+2)

= 3(x+2)*70÷70 - 2(x+2)

= 210(x+2)/70-2x-4

= 210(x+2)/66-2x

= 210(x+2)/2(33-x)

= 105(x+2)/33-x

C.) 5 kilograms

Step-by-step explanation:

1000 grams = 1 kilogram

To convert grams to kilograms we divide by 1000

5000g divided by 1000 kg = 5kg

May I Please Have Brainliest I'm trying to achieve a new rank

5,000 grams is equal to 5,000/1000 = 5 kilograms. The correct option is C

A unit of measurement used to describe mass or weight is the kilogram (kg). It is widely used all over the world to measure an object's weight because it is the International System of Units' (SI) fundamental unit of mass.

To convert grams to kilograms, you divide the number of grams by 1000 since there are 1000 grams in one kilogram.

So, 5,000 grams is equal to 5,000/1000 = 5 kilograms.

Therefore, the correct option is C. 5 kilograms.
