Answer:
The number of hours DeShawn drove before Shaun caught up = 5 hours
Step-by-step explanation:
Average speed of DeShawn = 30 mph
Average speed of Shawn = 50 mph
After driving for three hours Shaun caught up with DeShawn.
Distance traveled by Shaun in 3 hours,
Distance = Time x Average speed = 50 x 3 = 150 miles.
So DeShawn also travels 150 miles, we need to find time DeShawn taken to travel this 150 miles,
Distance = Time x Average speed
150 = Time x 30
Time = 5 hours.
The number of hours DeShawn drove before Shaun caught up = 5 hours
we are given
Since, we have to solve for x
so, we will isolate x on anyone side
Since, 7.25 is in denominator of x
so, we will get rid of 7.25 from denominator
that's why we will multiply both sides 7.25 to get rid of denominator
so, we get
so,
Answer is 7.25
Answer:
7x - 18
Step-by-step explanation:
x multiplied by seven = 7x
eighteen subtracted from product (7x) = -18
7x - 18
2. A exponential decay because it is decreasing by 4. 64÷4= 16 16÷4= 4 4÷4=1
3. Neither because it is arithmetic
