Answer:

30°, 45°, and 105°

Step-by-step explanation:

Find the value of x

2x + 3x+ 7x = 180

12x = 180

x = 180/12

x=15

Get the value of the angles

2x = 2(15)

3x= 3(15)

7x= 7(15)

The measure of the angles are 30°, 45°, and 105° respectively.

Mezclas de alimentos. Un chef repostero creó una solución de azúcar de 50 onzas constituida por 34% de azúcar con una solución d
Kay [80]

Answer:

Las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.

Step-by-step explanation:

Podemos estimar la proporción de ingredientes mediante el siguiente promedio ponderado:

0.34= \frac{0.2\cdot m_{A} + 0.4\cdot m_{B}}{m_{A}+m_{B}} (1)

Donde:

m_{A} - Masa de la solución al 20 %, en onzas.

m_{B} - Masa de la solución al 40 %, en onzas.

Podemos simplificar la formula como sigue:

0.2\cdot x + 0.4\cdot (1-x) = 0.34 (2)

Donde x es la proporción de la solución al 20 % dentro de la solución final, sin unidades.

Ahora resolvemos para x en (2):

0.4-0.2\cdot x = 0.34

0.2\cdot x = 0.06

x = \frac{0.06}{0.2}

x = 0.3

Este resultado quiere decir que la solución al 34 % es el resultado de 30 % de la solución al 20 % y 70 % de la solución al 40 %. Si conocemos que la solución final tiene una masa de 50 onzas, entonces las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.

I need this done plz
KIM [24]

Answer:

13. -28 = p

12. 5 = r

11. -12 = t

10. -8 = q

9. -77 = s

8. 9 = w

7. 12 = y

6. 3 = a

5. 9 = n

4. 3 = x

3. 12 = y

2. 5 = c

1. 5 = m

DON'T GET HOOKED

Step-by-step explanation:

13. 1 + p \div 7 = -3 \\ \\ p\div 7 = -4 \\ \\ -28 = p

12. 5[r + 4] = 45 \\ \\ r + 4 = 9 \\ \\ 5 = r

11. t \div 4 - 3 = -6 \\ \\ t \div 4 = -3 \\ \\ -12 = t

10. -4 + 11q = -92 \\ \\ 11q = -88 \\ \\ -8 = q

9. s \div 7 + 8 = -3 \\ \\ s \div 7 = -11 \\ \\ -77 = s

8. w \div 3 + 3 = 6 \\ \\ w \div 3 = 3 \\ \\ 9 = w

7. y \div 3 - 4 = 0 \\ \\ y \div 3 = 4 \\ \\ 12 = y

6. 3[a + 5] = 24 \\ \\ a + 5 = 8 \\ \\ 3 = a

5. 14 = 2n - 4 \\ \\ 18 = 2n \\ \\ 9 = n

4. 3x + 6 = 15 \\ \\ 3x = 9 \\ \\ 3 = x

3. 6y - 11 = 61 \\ \\ 6y = 72 \\ \\ 12 = y

2. 9c - 4 = 41 \\ \\ 9c = 45 \\ \\ 5 = c

1. 2m + 2 = 12 \\ \\ 2m = 10 \\ \\ 5 = m
