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:

Step-by-step explanation:

Answer:
6(9r-7)
Step-by-step explanation:
54r–42
Both 54 and 43 can be divided by 6
54/6 =9 and 42/6 =7
6*9r - 6*7
Factor out the 6
6(9r-7)
Answer:
4
Step-by-step explanation:
Variable: X = Unknown Number
2x + 4 = x + 8
2x - x = 8 - 4
x = 4
Check:
2(4) + 4 = 4 + 8
8 + 4 = 12
12 = 12
