19, because a negitive and a negive is a postive so you are going to add them instead of subtract them. Hope i could help :) <3
<span>A number considered in comparative relation to a whole.</span>
A.) 10x + 7.5 (0) =420
10x = 420
420 / 10 = 42
x = 42 > ( 42,0 )
10(0) + 7.5y = 420
7.5y = 420
420 / 7.25 = 56
y = 56 > ( 0,56 )
(42,0) (0,56)
B.) The x intercept means that there was 42 ,minutes spent biking. The y intercept means that there was 56 minutes spent in line skating.
C.) (21 ,28) - (14,37) - (28,18)
I believe the answer would be 2/4
The answer would
be 13/10
