Answer:
The distance covered by the second cyclist in 45 minutes is (3/4·b + 9) miles
Step-by-step explanation:
The given parameters are;
The distance between the two cyclist when they begin biking away from each other = 7 miles
The first cyclist's speed = 12 miles per hour
The second cyclist's speed = 12 + b miles per hour
Therefore, we have;
The equation for distance covered, d = Speed × Time
The distance covered by the second cyclist in 45 minutes, 
is given as follows;
45 minutes = 3/4 hour
= (12 + b) × 3/4 = (3/4·b + 9) miles
The distance covered by the second cyclist in 45 minutes = (3/4·b + 9) miles.
Answer:
X=65
Step-by-step explanation:
The picture is not very good, but i guess tht x is angle on the section. Right?
If it is true we have that:
The angle formed by two intersection chode is:
X=1/2(30+100)
X=130/2
X=65
Answer:
x = 7
Step-by-step explanation:
3x + 20 = 5x + 6
3x - 5x = 6 - 20
-2x = -14
x = 14/2
x = 7
the value of x = 7
If you get confused by logarithms, here's an easier way to think about this problem: What power of 2 equals 128? Well, we know 2^3 = 8, then 2^4 must equal 16. Doubling every times, we get 2^5 = 32, 2^6 = 64 and 2^7 = 128. So, the value of log₂128 is 7.
