Hi can someone explain to me this question or help thank you

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 plus change to minus

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

hope it helps you ☺️

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: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
