Answer:
15x + 3y = 10.
Step-by-step explanation:
you have to solve for y.
isolate the variable.
15x + 3y = 10
start by subtracting 15x on both sides.
3y = -15x +10
then divide both sides by 3
y = -15/3x + 10/3
simplify.
y = -5x + 10/3
10/3 can be written as 3.33
or 3 and 1/3

Answer:
4 3/8 miles
Step-by-step explanation:
We are told that: the scale on a map is 1 inch =2 1/2 miles.the distance between two streets on the map is 1 3/4 inches
If 1 inches = 2 1/2 miles
1 3/4 inches =
Cross Multiply
1 3/4 × 2 1/2/1
= 7/4 × 5/2
= 35/8
= 4 3/8 miles
The actual distance between these streets is 4 3/8 miles
