Answer: 1 inch= 25 miles
Step-by-step explanation:
Given : The actual distance from Washington to Fairview is 250 miles.
On a map, the distance from Washington to Fairview is shown as 10 inches.
It means , 10 inches on map shows 250 miles.
Applying unitary method, 1 inch on map will show =
i.e 1 inch on map will show =
Hence, the map’s scale is 1 inch= 25 miles.
Answer:
JL = 7
Step-by-step explanation:
If JK = 4, KL = 3x, and JL = 7x, what is JL?
From the diagram given in tbe question,
JK + KL = JL
4 + 3x = 7x
Collect like terms
4 = 7x - 3x
4 = 4x
4x = 4
x = 4/4
x = 1
Since JL from the diagram = 7x
Hence:
7 × 1 = 7
JL = 7
Part A:
Let 'x' be the number of windows cleaned.
Let 'y' be the total cost of cleaning 'x' windows.
Company A charges $6 per window and an additional $12 as service charges. So equation becomes
Company B charges $5 per window and an additional $15 as service charges. So equation becomes
Part B :
Cost for cleaning 8 windows.
Company A = =$60
Company B = =$55
Company B charges less for 8 windows.
Part C:
Cost for cleaning 6 windows.
Company A = =$48
Company B = =$45
Money saved by using company B is dollars.
