Answer:
Alexis = 59
Becca = 74
Cindy = 152
Step-by-step explanation:
a + b + c = 285
a = b - 15
c = 2b + 4
Well first you have to divide 620/20 which is 31. So his car goes 31 miles per gallon so you have 2 gallons and .25 of a gallon. So first off 2*31=62 miles then the 1/4 or .25. Multiply the 31 by .25 which is 7.75 now add 62 and 7.75 and you get how far his car can go.
62+7.75=69.75 miles
Answer:
5 feet
Step-by-step explanation:
The scale factor = 1 inch: 1.25 feet
The length of the Hally = 4 inches
The length of the hallway in real life is calculated as:
1 inch = 1.25 feet
4 inches = x feet
Cross Multiply
x feet = 4 × 1.25 feet
x feet = 5 feet
Therefore, the length of the Hallway in real life is 5 feet
First find midpoint of AB and lastly find the length of midpoint and C
The point slope form is y - y2 = m(x - x2)
