Can u help me plz and thank u

Elan Coil [88]

Answer:

Step-by-step explanation:

∠CBA + ∠ABD = 180 {linear pair}

2x - 6 + x +1 = 180

3x -5 = 180

3x = 180 +5

3x = 185

x = 185/3

x = 61 2/3

$2x-6=2*61\frac{2}{3}-6\\\\=2*\frac{185}{3}-6\\\\=\frac{370}{3}-\frac{18}{3}\\\\=\frac{352}{3}=117\frac{1}{3}$

Answer:

Step-by-step explanation:

We want to evaluate:

8a-1+0.5b

When a=1/4 and b=10.

We simply substitute the given values of as and b into the given expression,

$8a-1+0.5b=8(\frac{1}{4}) -1+0.5(10)\\=2-1+5\\=6$

The value of the expression is 6 for the give values of a and b.
