Answer: 
Step-by-step explanation:
Let be "x" the time in minutes a 150-pound person must walk at 4 mph to use at least 190 calories.
The amount of calories that a 150-pound person uses in 1 minute when walking at a speed of 4 mph is:

Therefore, knowing this, we can write the following proportion:

Finally, we must solve for "x" in order to find its value.
Multiplying both sides of the equation by 190, we get this result:

-4 is the first consecutive even integer following -6<span />
multiply all numbers together:
3*6*4*3 = 216 combinations
Answer:
Step-by-step explanation:
Alright, lets get started.
Suppose car was driven x miles in its 4 days trip.
Cost of a car rental is thirty dollar per day.
So, for 4 days, the car rental will be =
$
For 1 mile, it adds fifteen cents,
So, for x miles, the cost will be =
$
As per question, total rent is 180 $
Total rent will be =
Subtracting 120 in both sides



It means car was driven 400 miles. : Answer
Hope it will help :)
Answer:
x=47is your answer
3x-11=130(alternate angle)
3x=130+11
