Begin solving like you normally would. Add 2.25 to both sides and subtract 9x from both sides to try getting all x values on one side. However, you will find that after subtracting 9x from both sides, all x values go away, and you end with -2.25=1.6. This is not true (-2.25 is not 1.6), so the answer is no solution. There is no value of x which satisfies that equation.
Answer:
The object travels 144,000,000 feet.
Step-by-step explanation:
The distance the object travel after t seconds is given by:

How far would the object travel after 1.5 * 10^3 seconds
This is d when
, so 

The object travels 144,000,000 feet.
Answer:
19 hours.
Step-by-step explanation:
T = -14 -76 + 19h
The -14 is the cost for tolls, and the -76 is the cost for gas. The 19h is the amount she'll get per hour if she makes $19/hour. And T is the total profit
We want to solve for h if T = 260
260 = -14 -76 + 19h
+14 +14
274 = -76 +19h
+76 +76
350 = 19h
/19 /19
18.42 = h
She must work 19 hours.
Hope this helps!
The solution is subtract4.7x on both sides. Then you get -2.2x=7.7. Divide 7.7 by -2.2 and you get x= -3.5
