Hello there! And welcome to brainly . com, your #1 asking and answering site!

Answer: 20

<em>Why?</em>

So we need to substitute x for 3, so do that. (7x-1 => 7 * 3 - 1) Multiply 7 by 3. (7 * 3 == 21) Finally, subtract by one. (21 - 1 == 20) Therefore, your answer is 20.

Hope this helped you, and have a beautiful day!! ♥

7x - 1 = 20

7 times 3 is 21, 21 minus 1 is 20

Can you help with these 3 question pls it is due at 8 pm
ladessa [460]

Step-by-step explanation:

1. a + 130 =.180 ---> a = 50°

b + 130 + 120 = 360 ---> b = 110°

c + 120 = 180 ---> c = 60°

2. p + 44 = 180 ---> p = 136°

q + 44 = 180 ---> q = 136°

r = 44° (definition of vertical angles)

t = 34° (definition of vertical angles)

3. x = 50° (definition of vertical angles)

y = 50° (definition of alternate external angles)
