Answer:
<u>7 gallons were used for city driving and 17 gallons were used for highway driving</u>
Correct statement and question:
camison's minnan gets 14 miles per gallon for city driving and 19 miles per gallon for highway driving. At the beginning of the week, the 24-gallon tank was full. The family traveled 421 miles before running out of gas. How many gallons were used for city driving and how many were used for highway driving?

Step-by-step explanation:
x = Gallons for city driving
24 - x = Gallons for highway driving
Miles drove before running out of gas = 421
Now let's solve for x, writing the following equation:
14x + 19 (24 - x) = 421
14x + 456 - 19x = 421
-5x = 421 - 456
-5x = - 35
x = -35/-5
x = 7 ⇒ 24 -x = 17

Answer:
14.01, 493, 87
Step-by-step explanation:
Subtracting 28 from both sides tells you the range of values you need to be looking at.
28 + x > 42
x > 14
Any values more than 14 will make the inequality true. Three of them are ...
14.01, 493, 87
It would be -70. Your welcome
The percent would be 29%. You need to move the decimal to the right twice.
Answer:
Step-by-step explanation:
The inequality x ≥ -2 is graphed on a number line. -2 is the smallest possible value. All subsequent values are larger and therefore lie to the right of -2.
Thus, the following are true:
1. The ray will move to the right (because x begins at -2 and increases, which means moving to the right on the number line).
2. It will use a closed circle (because x = -2 is part of the solution set).
