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:

Put a dot on the -3 from the y-axis and draw a straight line from left to right.
Answer:
22w - 18
Step-by-step explanation:
To find the perimeter we have to add up all the sides
10w-10+w+1+10w-10+w+1
combine light terms
22w - 18 would be our answer
There are 2 pints in 1 quart
You have, for example, 6 pt of liquid
Since there are 2 pints in 1 quart, divide 6 and 2 together to get the qt amount you have
6/2 = 3
You have 3 qts
C is your answer
hope this helps
