The scale on a map is stated at
1:100,000
On a map, Layla estimates that the distance to her destination is 8cm.
If she is right with her estimate, how many kilometres is it to her destination?

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

answer:

c) the x-coordinate of the center of the circle increases by 3

answer: (-6,3)

step-by-step explanation:

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
