The value of the expression 2C+3B is 5m + 7
<h3>How to evaluate the expression?</h3>
The given parameters are:
C = m + 1
B = m + 5
To evaluate the expression 2C+3B;
We substitute C = m + 1 and B = m + 5
So, we have:
2C+3B = 2 * (m + 1) + 3 * (m + 5)
Expand
2C+3B = 2m + 2 + 3m + 15
Evaluate the like terms
2C+3B = 5m + 7
Hence, the value of the expression 2C+3B is 5m + 7

So basically you proportionize the triangles.
1) 52/x=20/5
2)cross multiply, you get--> 20x=260
3)divide 20 both sides, you get --> ×=13
Answer:
x=70* y=63*
Step-by-step explanation:
x=70* y=63* because these are alternate exterior angles , and because of that the angles are congruent. The angle y is congruent with the 63* angle and the angle x is congruent with the 70* angle.
I hope this helps you.
