Answer: C. 13 + 8x = 45
Step-by-step explanation:
She already has 13 dollars. This would be the b-value in the equation, thus eliminating options A and B because those two feature 13 as the m value.
She earns $8 per hour. Let x = number of hours walking dogs.
Since 8 is the slope, it would be attached to x, thus either C or D would be the correct response
Since Grace is adding 8 dollars per hour, not subtracting, D is incorrect, leaving C to be the correct answer.
 
        
             
        
        
        
Since there are 3 sides and each of those 3 sides are 9 cm, you would multiply 9*3 and your answer would be 27 cm.
        
             
        
        
        
I believe it’s c/100.
2=20
10 divided by 2 = 5.
Multiply 5 by 20. That equals 100.
        
             
        
        
        
4x2-36x+80=0
Answer 
X= 5
