Somebody please help with this math problem.19=4b-13
Veronika [31]
Start by adding 13 to both sides

19 = 4b-13
<span>19+13 = 4b-13+13
</span>32 = 4b
4b = 32

Then divide both sides by 4 to isolate b

4b = 32
4b/4 = 32/4
b = 8

So in the end, b = 8

Need a little help with one please
Pani-rosa [81]

Answer:

That would be the side-side-side (SSS) postulate, which states that if all the sides of a triangle are in a fixed ratio to all the corresponding sides of another triangle, then the two triangles are said to be congruent.

Step-by-step explanation:

Looking at triangles ABC and DEF, we notice that:

\frac{AB}{DE} = \frac{AC}{DF}=\frac{BC}{EF}

since

\frac{3}{18} = \frac{6}{36}=\frac{7}{42}=\frac{1}{6}

Let me know if you have further questions.

Serga [27]

<u>Answer</u>:

the length of chicken coop and the garden is of 40 feet.

<u>Explanation</u>:

Given that the garden is the length of the chicken coop, equal length

→ 3x + 12 = 6x – 16

→ 3x - 6x = -16 - 12

→ -3x = -28

→  x = \frac{-28}{-3}

→ x= 9\frac{1}{3}

→ x = 9.33 feet.

  • The garden length = 3(  \frac{-28}{-3}) + 12 → 40 feet
  • the chick coop length should be same as the garden length.
