Answer:
Step-by-step explanation:
-6.25x > -38 3/4
-6.25x > -155/4
Multiply by (-4)
 25x > 155
divide by 25,
x > 155/25
x > 31/5
x > 6.2

Answer:
BC = 28  ft
 ft
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal, that is
 =
 =  , substitute values
 , substitute values
 =
 =  ( cross- multiply )
 ( cross- multiply )
12BC = 340 ( divide both sides by 12 )
BC =  =
 =  = 28
 = 28 
 
        
             
        
        
        
Answer: x = 1 and y = 2
Given: 
y = -3x + 5
5x - 4y = -3
Since we are given y, let’s sub it in the second equation.
5x - 4(-3x + 5) = -3
5x + 12x - 20 = -3
17x = 17
x = 1 
After finding x, we can now find y. 
5(1) - 4y = -3 
-4y = -8
y = 2 
Checking: 
y = -3x + 5
2 = -3(1) + 5
2 = 2
5x - 4y = -3
5(1) - 4(2) = -3
-3 = -3
