4d-4=5d-8. more questions i just dont understand this topic

Step-by-step explanation:

4

Step-by-step explanation:

The topic is very easy ,just try to imagine as if the equation is happening to you.

It is so sure that a stranger cannot just enter your house without any permission, if such happens then the stranger must be an intruder.

Think of the equation given to you as two set of people . people with d and people without d , so what you will do is to connect the same type of people together , that is let 8 move to go and meet 4 and let 4d move to meet 5d , which gives

-4 + 8 = 5d -4d

  4 = d

two data sets with the same median will not have the same varaibility

step-by-step explanation:

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

1

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3
