28. This equation satisfies the condition
-x - 10 = -17

29. You can use this equation
x/5 + 5 = 0

30. The error is dividing the equation first by 3. The solution should have been
3x + 2 = 15
3x = 15 - 2
3x = 12
3x/3 = 12/3
x = 4

31.
x/4 - 6 = 2
x/4 = 2 + 6
x/4 = 8
x = 8(4)
x = 32

Find the area of a circle with radius, r = 5.64m.

Tpy6a [65]

Answer:

99.93 $m^{2}$

Step-by-step explanation:

1. The area of a circle is defined by the equation: A = $\pi r^{2}$

2. We can plug in the radius and solve the equation: A = $\pi *5.64^{2}$

3. A = π * 31.8096

4. A = 99.932

5. A = 99.93

Lori had $126.89 in her bank account. She deposited $21.49 into it and then wrote a check for her car repairs for $156.61.

kompoz [17]

Answer:

-8.23

Step-by-step explanation:

If Lori had $126.89 in her bank account and she deposited $21.49, she would be adding that to the amount of money in her bank account.

126.89+21.59= 148.48

Then subtract the amount of money the repairs costed.

148.48 - 156.61 = -8.23

Therefore Lori would have a balance of -$8.23.
