Answer: $-\frac{1}{2}$

Step-by-step explanation:

$\frac{5x}{6x+3}$

Restriction: 6x + 3 ≠ 0 denominator cannot be zero

Ok, make sure you put the powers correctly. I know what you mean but someone else may not. So it's step 2. This is because the 4 doesn't mean add a digit.

Find the value of x?

Answer:

145°

Step-by-step explanation:

See the attachment. Angles A, B, and C all belong to the triangle.

We know that A + B + C = 180° since the angles of a triangle always add to 180°. We also know that when two lines meet that their sum is also equal to 180°. So we can write for each interior angle the following:

Result

<A = (180 - 88) 72

<B = (180-x) 180-x

<C = (180 - 127) 53

The sum of angles A, B, and C is equal to 180:

72 + (180-x) + 53 = 180
