828
Step-by-step explanation:
Answer: 169.7
Step-by-step explanation:
Given that Air atmosphere level = 96kp
For every 1000m= 11.6/100 of 96kp decrease
For every 1000m= 96 - 11.6/100 × 96
= 96 - 11.14
= 84.86
If 1000m pressure decreases= 84.86
2000m pressure will decrease = ??
Let the missing value be x, and the equation be stated as:
1000 = 84.86
2000= x
Then cross multiply
1000x = 2000 x 84.86
1000x = 169,720
Divide both sides by 1000 to get the value of x
x = 169,720/1000
x =169.72 = ~ 169.7

Answer:
x= -19
y= -14
Step-by-step explanation:
Substitution.
It tells you what y is already. You substitute that into the second equation and then solve. Then you use that answer and substitute it back into the first equation's x, and then you'll get your full answer.
