Answer:

${( \frac{2}{3} )}^{ - 5} \times {( \frac{2}{3} )}^{ 12} = {( \frac{2}{3} )}^{ 3x - 2} \\ {( \frac{2}{3} )}^{ - 5 + 12} = {( \frac{2}{3} )}^{ 3x - 2} \\ - 5 + 12 = 3x - 2 \\ 7 = 3x - 2 \\ 3x = 7 + 2 \\ 3x = 9 \\ x = \frac{9}{3} \\ x = 3$

The leg of an isosceles triangle has a length 2x+4 and the base has length 3x. The

ikadub [295]

Answer:

$Base = 57$

Step-by-step explanation:

Given

$Length = 2x + 4$

$Base = 3x$

$Perimeter = 141$

Required

Determine the length of the base

The perimeter of an isosceles triangle is:

$Perimeter = 2*Length + Base$

$141 = 2 (2x + 4) + 3x$

$141 = 4x + 8 + 3x$

Collect Like Terms

$4x + 3x = 141 - 8$

$7x = 133$

Divide both sides by 7

$x = 19$

To get the base, we substitute 19 for x in $Base = 3x$

$Base = 3 * 19$

$Base = 57$

Write the ratio 4/7 over 1/8 in simplest form. How is the simplest form of the ratio 4/7 over 1/8 related to the simplest form o

PIT_PIT [208]

Answer:

Step-by-step explanation:

Ratio = 4/7 : 1/8

$=\frac{\frac{4}{7}}{\frac{1}{8}}\\\\=\frac{4}{7}*\frac{8}{1}\\\\=\frac{32}{7}$

= 32 : 7

$\frac{\frac{1}{8}}{\frac{4}{7}}=\frac{1}{8}*\frac{7}{4}\\\\=\frac{7}{32}$

= 7 : 32

Ratio 4/7 over 1/8 is the multiplicative inverse of the ratio 1/8 over 4/7
