Answer:

2¾

Step-by-step explanation:

$\\ \sf \frac{ | - 19 + 9| }{3} - \frac{ |14 - 22| }{9}$

$\\ \sf = \frac{ | - 10| }{3} - \frac{ | - 8| }{9}$

$\\ \sf = \frac{10}{3} - \frac{8}{9}$

$\\ \sf = \frac{30 - 8}{9}$

$\\ \sf = \frac{22}{8}$

$\\ \sf = \frac{11}{4}$

$\\ \sf = 2 \frac{3}{4}$

The answer is 140.

Interior angles equal 180…so 180-120-20= 40. 40 is your x value. Angles on a straight line equal 180, so 180-40=140.

Answer:

$b = \frac{t-5}{4}$

Step-by-step explanation:

Step1:-

Given 4 b+5=t

subtracting on both sides with 5 we get

$4 b+5-5 = t-5$

After simplification $4 b=t-5$

Dividing '4' on both sides , we get and simplification

$b = \frac{t-5}{4}$

now Final answer $b=\frac{t-5}{4}$
