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

about question number 4

5x=25

x = 25÷5 (change side change mark)

x = 5

questions that I don't show you how to think

let's get it by yourself

change side change mark. it's mean

if in equation is minus change to plus

if in equation is divided by change to multiply

if in equation is multiply change to divide by

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: x would be 1/8 and y would be -36

Step-by-step explanation:

To find put y you would plug in -6 for x. So it would be y=8(-6)+12. Then you multiply the 8 and -6 to get -48, y=-48+12. Then subtract 48 from 12 and that is -36 so y=-36. To solve for x you would plug in the y or 13 into the equation. So, 13=8x+12. Then you would have to solve. 12 minus 13 is 1 and the you are left with 1=8x then you divide 1/8 and 8x/8 and you get x=1/8. Hope this helped!

Answer: (-5,1)

Step-by-step explanation: that should be right

When you multiply or divide both sides of an inequality by a negative, you must switch the direction of the inequality sign. Please give this idea of your full attention. Even the most advanced algebra students will sometimes forget to switch the direction of the inequality sign when multiplying or dividing both sides of an inequality by a negative.

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

Answer:

2.04

Step-by-step explanation:

basically you want to do

4.08

     2

2.04

just divide 8 by 2 which equals 4 and then 0 divided by 2 isnt anything so you do 4 divided by 2 equals 2.

Hence:

[tex]m * x = Irrational[/tex]

(b) [tex]n * y[/tex]

n is a rational number while y is an irrational number.

And we know that:

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

Answer:

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.
