Answer:

x = 12

Step-by-step explanation:

Apply Thales' theorem

$\frac{ED}{CB} =\frac{AD}{AB}$

$ED=x$

$\frac{x}{6} =\frac{20}{10}$

$x=\frac{(20)(6)}{10} =12$

Hope this helps

Joshua uses a rule to write the following sequence of numbers 1/6,1/2,5/6,----------,11/2 What rule did Joshua use? What is the

Pani-rosa [81]

Answer: The missing number in the sequence is $\frac{7}{6}$

Step-by-step explanation:

Since we have given that

$\frac{1}{6},\frac{1}{2},\frac{5}{6},----------,\frac{11}{2}$

First term = a= $\frac{1}{6}$

Common difference = d is given by

$d=a_2-a_1\\\\\frac{1}{2}-\frac{1}{6}\\\\=\frac{6-2}{12}\\\\=\frac{4}{12}=\frac{1}{3}\\\\Similarly,\\d=a_3-a_2\\\\=\frac{5}{6}-\frac{1}{2}\\\\=\frac{10-6}{12}\\\\=\frac{4}{12}\\\\=\frac{1}{3}$

Therefore, it forms an arithmetic sequence.

Since, $a_4$ is missing,

So,

$a_4=a+3d\\\\a_4=\frac{1}{6}+3\times \frac{1}{3}\\\\a_4=\frac{1}{6}+1\\\\a_4=\frac{1+6}{6}\\\\a_4=\frac{7}{6}$

Hence, the missing number in the sequence is $\frac{7}{6}$

10 (w-4)=4 (w+4)+4w

eimsori [14]

Answer:

$w = 28$

Step-by-step explanation:

$10(w-4) = 4(w+4)+4w$

1. distribute

$10w - 40 = 4w +16 +4w$

2. collect like terms

$10w -4w - 4w = 40 +16$

3. solve

$2w = 56$

$w = 28$
