Question

me ajuda por favor!!!

Answer 1

Resposta:

01)

6x+5=8x-10

6x-8x=-10-5

-2x=-15 . (-1)

2x=15

x=15/2 ou 7,5

6 . 15/2+5=90/2+5=45+5=50°

8 . 15/2-10=120/2-10=60-10=50°

02)

x+32+32=180

x+64=180

x=180-64

x=116°

03)

2x-10=x+15

2x-x=15+10

x=25

Answer 2

Explicação passo-a-passo:

a) 6x+5°=8x-10°

6x-8x=-10°-5°

-2x=-15°

x=15/2°

x=7,5°

-------------

6x+5°=6×7,5°+5°=45°+5°=50°

8x-10°=8×7,5°-10°=60°-10°=50°

b)

32°+32°+x=180°

64°+x=180°

x=180°-64°

x=116°

c)x+15°=2x-10°

x-2x=-10°-15°

-x=-25°

x=25°
