Answer:
10
Step-by-step explanation:
We can write Bailey's equation as:
29 + 1.50x
and Riley's equation as:
20 + 2x
Where
x is the number of magazines sold
Since Riley sold 12, her total pay for that day would be:
20 + 2x
20 + 2(12)
20 + 24
$44
Now, how many magazines Bailey need to sell? We equate Bailey's equation to 44 and find x:
29 + 1.5x = 44
1.5x = 44 - 29
1.5x = 15
x = 15/1.5
x = 10
hence, Bailey need to sell 10 magazines to make same money as Riley

Answer:
D
Step-by-step explanation:
80 divided by 2 equals 40 and if you multiply it by 8 its 320 so the constant number is 40. So y=40x mean y=40^x
Answer:
(4,1)
Step-by-step explanation:
x+y=5
x- y=3
Add the equations together to eliminate y
x+y=5
x- y=3
--------------------
2x = 8
Divide each side by 2
2x/2 = 8/2
x = 4
Now we can find y
x+y = 5
4+y = 5
Subtract 4 from each side
4+y-4 = 5-4
y =1
