Is there a diagram or something to look at for this ...?
One way is to solve (it's easier)
x-9>29
add 9
x+9-9>29+9
x+0>38
x>38
just pick the numbers bigger than 38 as answer
47 is only number (38>38 is false)
answer is A
Answer:
Alicia has 9 dollars and Haley has 13 dollars.
Step-by-step explanation:
Let Alicia's money be 
. Hence, Haley's money will be
Together: 
.
Therefore, 
Subtract 4 from both sides:
Thus, 
. Alicia has 9 dollars.
Haley's amount: 
.
For this problem you can create a proportion.
Since 31,100 copies is 7.8% of the total copies spoke up to date you can make this proportion:
31,100. 7.8%
——— =. ———
x. 100%
Now you cross multiply and you will get
7.8x=3,110,000
After this you solve for x by isolating the variable.
7.8x/7.8. 3,110,000/7.8
x=398,717.949
Since the question asks you to round to the nearest whole number which is 7 then the final answer would be 398,718
Answer: There has been 398,718 copies sold to date.
“Z” is best described as a coefficient because it is a variable
