So because of PEMDAS you want to distribute the 2 to the parentheses so you'll get
6x-19=2x-2+11
Then you can just add like terms
6x-19=2x+9
Now you want to get all your variables on one side so you'd add 19 and subtract 2x
4x=28
Now you divide 28 by 4
x = 7
Answer:
a) -3 gallons per hour
b) y = -3x +14
Step-by-step explanation:
Rate of change is computed by dividing the amount of change by the interval over which it occurred.
<h3>a)</h3>
Here the amount of gas decreased from 14 to 2 gallons, so a decrease of 14-2 = 12 gallons. That occurred over a 4-hour period, so the rate of change is (-12 gallons)/(4 hours) = -3 gallons/hour.
__
<h3>b)</h3>
The initial amount was 14 gallons, so the equation for the line describing remaining gas will be ...
y = -3x +14 . . . . gas in the tank after x hours

Answer:
C. 82
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary. So ...
(x + 10°) + 88° = 180°
x = 180° -98°
x = 82°
