Do the ratios 5:3 and 13:8 form a proportion?
shepuryov [24]

Answer:

  No

Step-by-step explanation:

Each ratio is irreducible, and they are different. Hence they are not the same value, so cannot be a proportion. A proportion is two equal ratios.

  5 : 3 = 40 : 24

  13 : 8 = 39 : 24 . . . . not the same as 40 : 24

_____

<em>Examples of proportions</em>

  5/3 = 40/24 . . . is a proportion

  13/8 = 39/24 . . . is a proportion

Simplify the equation -4d - 37 = 7d + 18
exis [7]

Answer:

d=-5

Step-by-step explanation:

-4d-37=7d +18

move the terms to its correct side

-4d-7d=18+37

calculate the like terms together.

-11d=55

divide both sides by -11. both of the negavtive (-11) will cancel out and become d on the left and on the right 55 will be divided by -11 = -5. the 5 is negative because there's a negative -11 if there were a postive 11 it will be 5 instead of D=-5
