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

What is the solution to the system of equations? (–21, 9) (9, –21) (–1, 9) (9, –1)
Masja [62]

<u>The solution to the system of equations is the</u><u> point ( -1, 9 ).</u>

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 ).

The price of the box of 10 markers is $7. The price of the box of 24 markers is $14. All prices without tax, and the price of th
stepladder [879]

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
