Answer:
$21
Step-by-step explanation:
This can be easily solved by fraction 400/24=350/x
x=$21
 
        
             
        
        
        
Step-by-step explanation:
Angle A = 4x + 12 = 4(15) + 12 = 72°.
Acute is for angles that are less than 90°.
Obtuse is for angles that are between 90° and 180°, not inclusive.
Right is for angles that are 90°
Hence the answer is acute.
 
        
             
        
        
        
Answer: Fran's number is 70
Step-by-step explanation:
Let x represent Jen's number.
Let y represent Carrie's number.
Let z represent Fran's number.
When you add their numbers together you get 207. This means that 
x + y + z = 207 - - - - - - - - - -1
Jen's number is 9 more than Carrie's number. It means that 
y = x - 9
Fran's number is 3 less than Jen's number. It means that 
z = x - 3
Substituting y = x - 9 and z = x - 3 into equation 1, it becomes.
x + x - 9 + x - 3 = 207
3x - 12 = 207
3x = 207 + 12 = 219
x = 219/3 = 73
y = x - 9 = 73 - 9
y = 64
z = x - 3 = 73 - 3
z = 70
