AfilCa [17]

Respuesta:

192

Explicación paso a paso:

aₙ = a₁*rⁿ⁻¹

Hallando termino 1

a₇ = 3

r = 1/2

a₁ = ?

a₁ = aₙ / rⁿ⁻¹

a₁ = 3 / (1/2)⁷⁻¹

a₁ = 192

Pls answer me this all question

Scorpion4ik [409]

Answer:

a. $5 \frac{21}{40}$

b. $\frac{1}{42}$

Step-by-step explanation:

$a. \: 12 \frac{2}{5} - 6 \frac{7}{8}$

$\frac{62}{5} - \frac{55}{8}$

$\frac{62}{8} \times \frac{8}{8} - \frac{55}{8} \times \frac{5}{5}$

$\frac{62 \times 8 - 55 \times 5}{40}$

$\frac{221}{40}$

$5 \frac{21}{40}$

$b. \: \frac{3}{14} - \frac{4}{21}$

$\frac{3}{14} \times \frac{3}{3} - \frac{4}{21} \times \frac{2}{2}$

$\frac{3 \times 3}{42} - \frac{4 \times 2}{42}$

$\frac{1}{42}$

Hope it is helpful....

Need help Nnsndndndnddn

Ksju [112]

Answer:

A. x = 50

Step-by-step explanation:

x° + (x + 10)° + (x + 20)° = 180° (sum of interior angles of a triangle)

Solve for x

x + x + 10 + x + 20 = 180

Add like terms

x + x + x + 10 + 20 = 180

3x + 30 = 180

Subtract 30 from each side

3x + 30 - 30 = 180 - 30

3x = 150

Divide both sides by 3

3x/3 = 150/3

x = 50
