Answer 1

Answer 17:

14.13 (bar)

Step-by-step explanation:

11.4565 bar +2.67bar

first 11.4565 bar

x=11.4565 bar ----1

Multiply by 100 on both sides

100x= 1145.6565....----2

then again multiply by 100 on both sides

10000x=114565.6565.......-----3

subtracting eq. 2 from eq. 3

10000x-100x=114565.6565.....-1145.6565.....

9900x=113420

x=113420/9900

x= 11342/990

secondly 2.67bar

x=2.6767....----1

multiply by 100 on both sides

100x= 267.6767.....-----2

subtracting eq.1 from eq.2

100x-x= 267.6767.....2.6767....

99x=265

x = 265/99

now 11.4565 bar +2.67 bar

11342/990+265/99

13992/990

14.133333...... or 14.13 bar
