129.8/22= 5.9 lb
<span>$91.30/22= $4.15 a gallon
That is my answer.</span>
20.50 into a fraction is 41/2. Since 20 is already a whole number, there is no need to convert it. Since .50 is a decimal, I have to convert it to a fraction, which is 1/2. I end up with the mixed number 20 1/2. Since I need to convert it to a fraction, I have to simplify it. 20 1/2 written as a fraction greater than 1 is 41/2.
Hope this helped !!

1)2x
2)2x-20%------> 2x-0.4x
</span>algebraic expression<span>-----> [2x-0.4x]---------> 1.6x

1)x/5
2)(x/5)*8-------> 8x/5

Part B)
</span>[2x-0.4x]=[8x/5]---------> 1.6x=8x/5--------> 5*(1.6x)=8x-------> 8x=8x
therefore
<span>the two methods give the same answer
the answer is 1.6x</span>
Are the numbers after the “K” exponents??
The perimeter of a triangle is given by:
Perimeter = sum of three sides
We are given perimeter = 112 in.
Hypotenuse = 50 in.
Let us say the other two sides are a and b.
So , we have
...............(2)
In a right angle triangle we can apply pythagorean theorem,
a² + b² = c²
here c is hypotenuse which is 50 in.
a²+b² = 50²
a²+b² = 2500............(2)
Plugging the value of a from equation (1) in (2)
Factorising ,
So we have two values of b
b=14 and b=48
If b=14, a=48
If b=48, a=14
