-4(8-(-3))+7
Remove the parentheses, negative with negative will equal a positive so the new equation will be -4(8+3)+7. So 8+3=11, -4(11)+7. -4(11)=-44 and then add -44+7 which will equal -37
        
             
        
        
        
Answer: -9.1 
Explanation 
-3x +12.4=39.7 
First minus 12.4 from both sides 
-3x +12.4=39.7 
 -12.4 -12.4
-3x=27.3 
Now devid both sides by -3 
X= -9.1
        
             
        
        
        
85/95 is equal to 0.8947
64/76 is equal to 0.842
Therefore, 85/95 is greater

Answer:
D
Step-by-step explanation:
Imagine this as a right angle triangle, where the diagonal length is the hypotenuse, the length is one side, and the width is the other.
We can therefore use Pythagoras' Theorem (or Pythagorean Theorem) to solve. The formula for this is a²+b²=c², where c is the hypotenuse, and a and b are the sides.
We can input the values we know to this formula to get the width. This gives 110²+b²=133.14² or 12100+b²=17 726.2596. 
From there subtracting 12100 from both sides gives b²=5626.2596.
Square rooting b isolates it, leaving b=75.0083969.
Since the value of the diagonal was approximate, this can be assumed the b is 75m.
