Answer:
Jay did.
Step-by-step explanation:
Jay ate 2/3 of a pizza, while Darrell ate 2/4
2/3 is greater, like 6/9, but, 2/4 is only half, like 4.5/9
For the first question you shade in the bar to the 20% mark as she has saved 20% of the money needed for her jacket. To complete the bar you add the amount of how much each percentage is in dollars. We know 20%=$15 and the percentage goes up 20% each time so you keep adding $15 on. For question 2 the bar is half way between 0 and 20 and half of 20 is 10. As 10 is half of 20 we half 15 to get $7.50

example
we see
g=(1,2)
theefor
g(1)=2
a.
f(4)=1
g(1)=2
g(f(4))=2
b.
g(-2)=4
f(4)=1
f(g(-2))=1
c.
f(3)=5
g(5)=5
f(5)=0
f(g(f(3)))=0
Answer:
-40
Step-by-step explanation:
-7 x 7 + 9 x (-1) / (-1)
-49 + 9 x (-1) / (-1)
-49 - 9 / (-1)
-49 + 9
= -40
