Are you doing 8 times 60 or8x = 60?

One possible system of two equations is ...
x = -2
y = -3 .
9) 35% of the 12,000 are 50-64 years old.
12,000 x 0.35 = 4,200
4,200 people were 50-64 years old
10) 25% of 596 people are over 64 years old
596 x 0.25 = 194
194 people were older than 64
11) yes, he is correct because 450 x 10%=45 and 450 x 30%=135
It depend on the center of the dilation. For example, if the point (-6,4) is the center itself, than it will remain the same.
If the dilation has the origin as center, instead, the factor 1/2 simply means that you have to divide all coordinates by 2: the point (-6,4) becomes the point (-3,2)
