La suma de dos numeros es 14 y el doble del primer numero sumado con el segundo es 23 cuales son los numeros

Answers

Answer:

Primer número = x = 9

Segundo número = y = 5

Step-by-step explanation:

La suma de dos números es 14 y el doble del primer número sumado con el segundo es 23 ¿cuáles son los números?

Representamos:

Primer número = x

Segundo número = y

La suma de dos números es 14

x + y = 14 ..... Ecuación 1

x = 14 - y

El doble del primer número sumado al segundo es 23

2x + y = 23

Sustituimos 14 - y por x

Por eso:

2 (14 - y) + y = 23

28 - 2 años + y = 23

-y = 23 - 28

-y = -5

y = 5

Resolviendo para x

x = 14 - y

x = 14 - 5

x = 9

Por lo tanto,

Primer número = x = 9

Segundo número = y = 5

Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How much will Colin have after 10 years to the nearest pound?​

Answers

Answer:

£3,692

Step-by-step explanation:

First four years

A = p(1 + r/n)^nt

P = £2350

r = 4.2% = 0.042

n = 1

t = 4

A = p(1 + r/n)^nt

= 2350(1 + 0.042/1)^1*4

= 2350(1 + 0.042)^4

= 2350(1.042)^4

= 2350(1.5789)

= 2770.42

A = £2770.42

Next 6 years

P = £2770.42

r = 4.9% = 0.049

n = 1

t = 6

A = p(1 + r/n)^nt

= 2770.42(1 + 0.049/1)^1*6

= 2770.42(1 + 0.049)^6

= 2770.42(1.049)^6

= 2770.42(1.3325)

= 3691.59

A = £3691.59

Approximately £3692
