| 3x - 1 | + 7 = 2
| 3x - 1 | = 2 - 7
| 3x - 1 | = -5.....no solution because an absolute value cannot equal a negative number.
| 2x + 1 | + 4 = 3
| 2x + 1 | = 3 - 4
|2x + 1 | = -1...same thing...no solution..cannot equal a neg. number
so Eq. 1 and Eq. 2 both have NO SOLUTIONS :)
Answer:

10 ways without pennies. Pennies can be substituted for any quarter, dime, or nickel, so ...
8 ways to have 5 pennies
7 ways to have 10 pennies
6 ways to have 15 pennies
5 ways to have 20 pennies
4 ways to have 25 pennies
3 ways to have 30 pennies
2 ways to have 35 pennies
2 ways to have 40 pennies
1 way to have 45 pennies
1 way to have 50 pennies
For an additional 39 ways with pennies.
There are a total of 10 +39 = 49 ways to make change for 50¢.
The value of k is 735 feet.
<h3>What is a scale drawing? </h3>
