Answer:
You can always ask the tutor they give the correct answer :))
 
        
             
        
        
        
Given,  
∠AOE = 30°
∠DOB = 40°
So, ∠EOD = 180 - (30+40)           [angles on a straight line]
                 =  180 - 70
                 =  110
∠EOD = ∠COF                             [ vertically opposite angle]
∴ ∠COF = 110°
 
        
                    
             
        
        
        
Well, 10x4=40 because 10+10+10+10=40 and that means your answer must be 40 ones or you asked something else.
        
             
        
        
        
Answer:
1.) He still owes $100 of debt
2.) 1 rose would be .75 cents and 1 carnation would be .90 cents
3.) C 8 and 3/8
Step by Step explanation
(/ means divided by in the first 2 equations but / in the last question is for the fractions.)
1.) _(1,500 / 3 =500. 1,500 - 500 =1,000 / 5 =200 x 3 =600. 700 - 600 =$100)
2.)_(1.50/2 =.75 cents. 2.70/3 =.90 cents.)
3.) i first added the fractions ( i equalized them) then i added the whole numbers (the u in the equation was to separate the whole num. and fraction )
Before i equalized it: (6u3/4 + 1u1/8 = 7u1/8 + 1/8 = 8u3/8)
After i equalized it: (6u6/8 + 1u1/8 = 7u1/8 + 1/8 = 8u3/8)
 
        
             
        
        
        
Step-by-step explanation:
-4x + 3 < 23 
-4x < 20 
x > -5 
hmm,I don't think we need to put equal sign instead of (<) , for when we started calculating. 
we can just keep the question as it is and calculate.
