Answer:
6 bows
Step-by-step explanation:
First find a common denominator. In this case, it would be eight. So now you would multiply your numerator by however much you multiplies your denominator.
3/4 would become 6/8.
6/8 divided by 1/8 is 6.
Answer:
n=11 or n=-3
Step-by-step explanation:
Consider the quadratic equation 
First, remind the formula
To complete the square, note that
Hence, we need 
Add 16 to both sides of equation:
Answer:
A. (3, -3)
Step-by-step explanation:
Let's use the addition/elimination for this to avoid fractions. You could solve one of the equations for y or x and then sub that value into the other equation, but you would have to deal with fractions along the way, so let's just not. Using the addition/elimination (they're the same thing; math books sometimes use one or the other), we line up our equations:
5x + 2y = 9
2x - 3y = 15
It looks like if we want to eliminate the y terms, we can multiply the top equation by 3 and the bottom equation by 2 to get a whole new set of equations:
15x + 6y = 27
4x - 6y = 30
Now we can see that when we add down the columns, the y's cancel each other out. 6y's minus 6y's leaves us with no y's. What we are left with is
19x = 57 so
x = 3.
Now we will sub that 3 back in to either of the original equations to solve for y:
2(3) - 3y = 15 and
6 - 3y = 15 and
-3y = 9 so
y = -3
The solution set then is (3, -3)
A. About $80 ; 53 round down to 50, 67 round up to 70
B. $53 + $67 = 120
200 - 120 = 80
Exactly $80
Answer:
the area product is simply (3x+5).(x+7 which can multiply if desired to obtain highlight3x/2+ 26x + 35.
You can use Completion of the Square on the trinomial product to put this trinomial into standard form. You would want this form to be like (x-h)2 +k.
