<span>r = 300+y , b= 2*r
b=2(300+y)
b= 600 +2y
2y = b - 600
y = b/2 - 300</span>

<h3>
The exercise is: " Evaluate
when
and 
</h3>
Given the following expression:

You can follow these steps in order to evaluate it:
1. Substitute
and
into the expression provided in the exercise:

2. Solve the multiplications. Remember that:

Then:

3. Reduce the fraction. Notice that the numerator 6 and the denomiantor 4 can be both divided by 2. Then:

4. Solve the addition:

Since the number 21 has a denominator 1, the Least Common Denominator is:

Then, the sum is:

Answer:
7.21 units
Step-by-step explanation:
GIven data
Point 1= (8,3)
x1= 8
y1= 3
Point 2= (2,7)
x2= 2
y2= 7
The expression for the distance between two points is given as
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((2-8)²+(7-3)²)
d=√((-6)²+(4)²)
d=√36+16
d=√52
d= 7.21
Hence the distance between the points is 7.21 units
