Answer:

x = 4.

Step-by-step explanation:

2x + 3(5x - 7) = 47

2x + 15x - 21 = 47

17x - 21 = 47

17x = 68

x = 68/17

x = 4.

Answer:

x = 4

Step-by-step explanation:

   2x + 3(5x - 7) = 47

⇔ 2x + 15x - 21 = 47

⇔ 17x - 21 = 47

⇔ 17x = 47+21

⇔ 17x = 68

⇔ x = 68/17

⇔  x = 68÷17 = 4

Answer:

A  16°

B  -8°

C  6°

D  -16°

E  -4°

Step-by-step explanation:

Look at 0° and 10°. There are 5 lines from one to the other, so each line represents 2°.

A

3 lines above 10° = 10° + 3 * 2° = 10° + 6° = 16°

B

1 lines above -10° = -10° + 2° = -8°

C

3 lines above 0° = 0° + 3 * 2° = 0° + 6° = 6°

D

2 lines above -20° = -20° + 2 * 2° = -20° + 4° = -16°

E

3 lines above -10° = -10° + 3 * 2° = -10° + 6° = -4°
