7/9_____4/9

Answers

< is the answer , trust me

Think of fractions like a pizza pie, the more parts it's cut into the less everyone will have. 7/9 is smaller than 4/9 because of the remainder of what would be left over if this was actual pie.

7/9 is less than (the first symbol) 4/9

For which function is the ordered pair (4, 12) not a solution?y = 3x
y = x + 8
y = 16 - x
y = 8 - x

Answers

It's D since 8 - 4 = 4, not 12.

Answer:

Y=8-x

So the answer is in fact D.

What equation models the data in the table if d = number of days and c = cost?Days
Cost
2
16
3
24
5
40

48

d = 8c
c = d + 8
c = d + 8d
c = 8d

Answers

Answer:

Correct option is:

c=8d

Step-by-step explanation:

Days Cost

2 16=2×8

3 24=3×8

5 40=5×8

6 48=6×8

As we can clearly observe from the table above that if d is the number of days then the cost c is written as:

c=8d

Hence, Correct option is:

c=8d

D)

The cost is a direct variation of the days by a factor of 8.
