Answer:

x = 11

Step-by-step explanation:

Given the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{3x+3}{x+7}$ = $\frac{38}{19}$ = 2 ( multiply both sides by x + 7 )

3x + 3 = 2(x + 7)

3x + 3 = 2x + 14 ( subtract 2x from both sides )

x + 3 = 14 ( subtract 3 from both sides )

x = 11

Find 4/7 divided by 7/8

Reika [66]

If you divide a fraction by another fraction, this is equivalent to mupltiplying by its inverse:

so $\frac{4}{7}$ divided by $\frac{7}{8}$

is equivalent to

$\frac{4}{7}$ multiplied by by $\frac{7}{8}$

which is

$\frac{4}{7}* \frac{7}{8}= \frac{4*7}{7*8}= \frac{4}{8}= \frac{1}{2}$

so the answer is $\frac{1}{2}$ which is also 0.5
