The answer is 3.785, but rounding it to the nearest hundredth is 3.78 or 3.79, depending on rather they wanted you to take the 5 and round up or just leave it off.
        
             
        
        
        
Answer:
Jay's bread size is 220% of the original size.
Step-by-step explanation:
The question is incomplete.
The complete question is as follows.
Jay is letting her bread rise. After 3 hours,her bread is at 11/5 of its original size. What percent of its original size is jays bread dough?
Solution:
Let the original bread size be =  units
 units
After 3 hours the bread rises =  of the original size
 of the original size
New size of bread =   units
 units
Percent of original size the new bread is

Answer:
If you are just looking for a simplified answer then the answer is -7x - 3.
 
        
             
        
        
        
-x - y = 8
2x - y = -1
Ok, we are going to solve this in 2 parts.  First we have to solve for one of the variables in one of the equation in terms of the other variable.  I like to take the easiest equation first and try to avoid fractions, so let's use the first equation and solve for x.
-x - y = 8      add y to each side
-x = 8 + y      divide by -1
x = -8 - y
So now we have a value for x in terms of y that we can use to substitute into the other equation.  In the other equation we are going to put -8 - y in place of the x.
2x - y = -1
2(-8 - y) - y = -1      multiply the 2 through the parentheses
-16 - 2y - y = -1      combine like terms
-16 - 3y = -1            add 16 to both sides
-3y = 15                   divide each side by -3
y = -5
Now we have a value for y.  We need to plug it into either of the original equations then solve for x.  I usually choose the most simple equation.
-x - y = 8
-x - (-5) = 8            multiply -1 through the parentheses
-x + 5 = 8                subtract 5 from each side
-x = 3                      divide each side by -1
x = -3
So our solution set is
(-3, -5)
That is the point on the grid where the 2 equations are equal, so that is the place where they intersect.
        
             
        
        
        
Answer: second option.
Step-by-step explanation:
 You must apply 
 Then, given the right triangle and the angle D, the opposite side and the hypotenuse of the triangle are the following:
 
 Therefore, when you substitute values, you have:
 
 Reduce the fraction, then you obtain:
