Answer:
Hamish and Harry work as plumbers. Harry earns a dollar an hour more than 5/4 the amount hamish earns per hour. harry earns per hour is 2$ less than 7/5 the amount hamish earns per hour. how much do each of them make an hour
Step-by-step explanation:
Let
x is the  amount Harry earns 
y is the amount Hamish earns 
x=(5/4)y+1 ⇒ (x-1)*4/5 = y-------- equation 1
x=(7/5)y-2⇒ (x+2)*5/7 = y-------- equation 2
equals 1 and 2
(x-1)*4/5 = (x+2)*5/7
 (4x-4)/5 = (5x+10)/7
 (4x-4)*7 = (5x+10)*5
28x-28 = 25x+50
 28x-25x = 50+28
 3x = 78
 x = 26
substitute x = 26 for y=(x-1)*4/5
y = (x-1)*4/5
y =  (26-1)*4/5
 y = 20
the answer is
<h3>Harry earns $26 an hour</h3><h3>Hamish earns  $20 an hour</h3>
 
        
                    
             
        
        
        
Answer:
A 1/2
Step-by-step explanation:
Ratio of short length to hypotenuse
= cos60
= 1/2
 
        
             
        
        
        
26.   2x^2 +4x -10 = 0       (-4 + - (root(4^2 - 4*2*-10)))/2*2   =   
(-4 + - (root(96)))/4
(-4 + (root(96)))/4  ≈  1.45
(-4 -  (root(96)))/4  ≈  -3.45
27. f(x) = 0 when any of the components that multiply together equal 0 for this function therefore   x -2 = 0    x +3 = 0    x -5 = 0   so   f(x) = 0 when x = 2, -3 or 5 
28. It looks like it shows you how to do it
