What is the value of x​

Mathematics
1 answer:
Artemon [7]3 years ago
4 0

Answer:

45 degrees

Step-by-step explanation:

Angles on a straight line add up to 180 degrees.

Thus, x+3x=180

4x=180

Divide both sides by 4:

\frac{4x}{x} =\frac{180}{4}

x=45

Help me plzzzzzzzzz<br> solve for x
Svet_ta [14]

Answer:

7) \frac{x+20}{x}=\frac{46}{30}

30(x+20)=46x

30x+600=46x

46x-30x=600

16x=600

x=75/2

x=37.5

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

8) \frac{10}{3x+1} =\frac{22}{7x-1}

10(7x-1)=22(3x+1)

70x-10=66x+22

70x-66x=22+10

4x=32

x=\frac{32}{4}

x=8

<u>---------------------</u>

hope it helps...
