First lets add the 2 distances on the map:
3 3/4 + 5 1/4 = 9 inches ( 3/4 + 1/4 = 1, 3+5 = 8, 8+1 = 9 )
1/2 inch on the map = 4 miles
there are 2 1/2 inches to 1 inch so 4 miles x 2 = 8 miles to 1 inch
so now multiply 9 inches x 8 miles = 72 total miles
A)1.5 goals per match
b) 1.5x35= 52.5 so 53
Assuming she is consistent

What is the solution to a system of linear equations?
If you have a system of equations that contains two equations with the same two unknown variables, then the solution to that system is the ordered pair that makes both equations true at the same time.
The system of equations
y = -3x + 6 ...................(1)
y = 9 .................(2)
Substitute equation (2) in equation
9 = -3x + 6
subtract both sides
9 - 6 = -3x + 6 - 6
3 = -3x
Divide by -3 both sides
x = -1
the solution is the point ( -1, 9 )
Therefore,the solution to the system of equations is the point ( -1, 9 ).

<u>The complete question is -</u>
Y = –3x + 6 y = 9 what is the solution to the system of equations? (–21, 9) (9, –21) (–1, 9) (9, –1)
Answer:
see below
Step-by-step explanation:
10 markers =7 dollars
Divide each side by 10
10/10 = 7 /10
1 marker = 7/10
y =7/10 x where y is the cost and x is the number of markers
24 markers =14 dollars
Divide each side by 24
24/24 = 14 /24
1 marker = 7/12
y = 7/12 x where y is the cost and x is the number of markers
