Answer: 
A)  See attached.
B)  Cheryl owes the bank more.
Step-by-step explanation: 
Given account balances:
John:  -$2.75 Cheryl:  -$3.00 Andrew:   $2.75 (Andrew has as much savings in his account as the amount John owes).
<h3><u>Part A</u></h3>
Draw a straight, horizontal line with arrows on both ends. Place a tick in the center of the line and label it zero. Draw 4 evenly spaced ticks either side of the zero. Number the ticks to the right of the zero 1, 2, 3 and 4. Number the ticks to the left of the zero -1, -2, -3, and -4. Mark -2.75, -3 and 2.75 on the number line. Label the marks with John, Cheryl and Andrew. (See attached number line).
<h3><u>Part B</u></h3>
The <u>absolute value</u> of a number is its <u>positive numerical value</u>.
To calculate how much John and Cheryl owe the bank, take the absolute values of their account balances:
As 3.00 > 2.75, Cheryl owes the bank more.

Answer: 
Step-by-step explanation: 
The formula for the volume of a sphere of radius r is V = (4/3)(pi)r^3.
Here, with r = 3 in, the volume is
V = (4/3)(3.14)(3 in)^2, or  V  =  36(pi)(27 in)^3 = 36pi in^3

Answer: 
11x + 12
Step-by-step explanation: 
( 4x + 12 ) + 7x
Remove parentheses.
= 4x + 12 + 7x
Group like terms.
= 4x + 7x + 12
Add similar elements: 4x + 7x = 11x
= 11x + 12
 
        
                    
             
        
        
        
The outside angle of B needs to equal 180 - 79 = 101 degrees.
 The 3 outside angles of a triangle need to equal 360 degrees.
Set up the equation with what we know:
X + (x+5) + 101 = 360
Simplify:
2x + 106 = 360
Subtract 106 from both sides:
2x = 254
Divide both sides by 2:
 x = 254 / 2
x = 127
