$7 was paid to park the car for 3 hours.

3 hours cost $7 to park

1 hour = $ (7/3)

So every 1 hour cost $(7/3)

Therefore cost in dollars, c = (7/3)*p

Therefore c = (7/3)p, where c is the cost in dollars of parking and p is the number of hours.

Joe ate twice as many pieces of Halloween candy as Ed. Together they ate 48 pieces.

gulaghasi [49]

Answer: 16

Step-by-step explanation:

Let the number of candy Ed took be denoted as "x"

Since Joe ate twice the amount of candy Ed ate, then the number of candies joe ate will be denoted as "2x"

Since all together they ate a total of 48 candies, then the sum of the candies eaten by Joe and Ed is what gives a total of 48

This means:

2x + x = 48

3x = 48

X = 16.

Another correction (Tried these on my own hand but got confused)

Answer: Triangle: x = 40 Line: x = 10

Explanation:
All angles of a triangle adds up to 180. So x + 50 + 90 (the square box represents a 90° angle) = 180
Simplify: x + 140 = 180
So x = 40°

A straight line is 180°
so 7x+110=180
7x= 70
x=10
