The value of x is: 180° - 100° - 45° = 35°
Answer:
x = 4
Step-by-step explanation:
We have the algebraic expression 3x + 16 = 7x and are asked to solve.
When we need to solve for x, we need to get x alone always.
So 3x + 16 = 7x.
Subtract 3x from both sides :
16 = 4x
Divide 4 from both sides :
x = 4
If you graph this scenario, the number of gallons of gas left will be on the y-axis while the number of miles traveled will be on the x-axis.
The line will be going downwards as the miles get longer. This is because the number of gallons of gas left will decrease as Janelle drives farther.
Assuming that Janelle initially had 10 gallons of gas and 1 mile consumes 1 gallon.
