Answer:
Step-by-step explanation:
(6x + 2)° + 42° + 58° = 180°
6x + 2 = 180 - 100
6x = 78
x = 13
Answer:
13
Step-by-step explanation:
There are 180 degrees in a triangle
58 + 42 + (6x +2 ) = 180
98 + (6x + 2) = 180
Subtract 98 from 180.
6x +2 = 82
Subtract 2 from 82
6x = 80
x = 13.333 or 40/3

Resuelva y responda a la pregunta: Andrés es mayor que su hermano Alex. Dentro de 3 años, la edad de Alex será la edad que tiene ahora Andrés y, dentro 9 años, la edad de Andrés será el doble de la edad que Alex tiene ahora. ¿Qué edades tienen los hermanos?
Answers
Answer:
Andrés tiene 15 años y Alex tiene 12 años.
Step-by-step explanation:
Como el enunciado dice que dentro de 3 años, la edad de Alex será la edad que tiene ahora Andrés puedes escribir una ecuación que indique que la edad de Andrés es igual a la edad de Alex más 3:
x=y+3, donde:
x es la edad de Andrés
y es la edad de Alex
Además, como se indica que dentro 9 años, la edad de Andrés será el doble de la edad que Alex tiene ahora puedes escribir una ecuación que indique que la edad de Andrés más 9 es igual a dos veces la edad de Alex:
x+9=2y
Ahora puedes reemplazar x=y+3 en x+9=2y y despejar y:
y+3+9=2y
12=2y-y
y=12
Finalmente, puedes reemplazar el valor de y en x=y+3 para encontrar el valor de x:
x=y+3
x=12+3
x=15
De acuerdo a esto, la respuesta es que Andrés tiene 15 años y Alex tiene 12 años.

A bill of $424 was paid with $5 bills and $2 bills. A total of 128 bills were used. How
many of them were fives?
Answers
Answer: 56
Step-by-step explanation:
Let the number of $5 be x
Let the number of $2 be y.
Based on the information given, we can form an equation as:
x + y = 128 ........ i
5x + 2y = 424 ....... ii
Multiply equation i by 2
Multiply equation ii by 1
2x + 2y = 256 ...... iii
5x + 2y = 424 ....... iv
Subtract iii from iv
3x = 168
x = 168/3
x = 56.
Therefore, there were 56 $5 bills.

Answers
Answer:
x = 557 to the nearest whole number
Step-by-step explanation:
The triangle is divided into two right triangles
Using the SOH CAH TOA identity
tan theta = opp/adj
tan 29 = (x/2)/502
x/2 = 502 tan 29'
x/2 = 278.26
x = 278.26 * 2
x = 556.52
x = 557 to the nearest whole number

Answer:
4. (2,1) 5. (-2,1) 6. (8, 80)
Step-by-step explanation:
4.2x + 4y - 2x + 2y = 8 - 2
6y = 6
y = 1
2x + 4 = 8
2x = 4
x = 2
(2,1)
5.3x + 4y + 6x - 4y = -2 - 14
8x = -16
x = -2
-6 + 4y = -2
4y = 4
y = 1
(-2,1)
6.multiply first equation by 4
4y = 40x
4y + 40x + 6y = 40x + 800
10y = 800
y = 80
80 = 10x
x = 8
