Answer:
x = -3.1832
Step-by-step explanation:
3 1/3x-5.3=-2
3.33x-5.3=-2 Change fraction into decimal
5.3*-2= -10.6 rearrange
3.33x=-10.6 rearrange
10.6/3.33 = -3.1832 divide
Answer:
4 hours
Step-by-step explanation:
- Step One: Define Variables -
Let x be the # of hours spent using the vehicles
- Step Two: Make Equations -
Jose: 4 + 2.5x
Elaine: 10 + x
If they spend the same amount then that means:
Elaine's price = Jose's price, therefore:
4 + 2.5x = 10 + x
1.5x = 6
x = 4
At 4 hours, both prices are the same.

A triangle has to equal to 180 degrees, add 65 and 33 together to get 98 degrees, subtract 180 from 98 to get 82 degrees. Part B is self explanatory.
Answer:
A quarter 
of one lap of the track.
Step-by-step explanation:
Three students ran ran a relay and took turns running equal parts of the track.
